EN60947-5-1 「电气机械控制电路设备」的EN规格。 和IEC60947-5-1的内容相同。 使用范围 开关按用途来分类。 请参考下面的例子。
(1)活塞型 根据密封方法不同,有表中的A型和B型2个种类。 A型是用O型环 或薄膜密封的,由于密封橡胶没有外露,在抵制工作机械的切割碎 屑方面功能较强大,但其反面影响是,有可能会将砂子、切割粉末 等压入活塞的滑动面。B型虽然不会把砂子、切割粉末等压入,且 密封性能优于A型,但由于炽热的切割碎屑飞溅过来,有可能会损 坏橡胶帽。因此,要根据使用场所的不同选用A型或B型。而柱塞 型仍然通过柱塞的往复运动压缩或吸进空气。 为此,如果长时间将柱塞压入,限位开关内的压缩空气逸失,内部 压力将与大气压相同,即使急于让柱塞复位,柱塞却有迟缓复位的 倾向。为了避免发生这种故障,设计时请参见199页。

They are used wherever motion sequences analogous to the actuation direction are controlled by hand. They are ideal for raising, lowering and triggering movements to the right and left, just to name same few possibilities.EUCHNER joysticks are used in the steel and construction industry, in machine tools, for transport and conveyor systems, in thecertification, the devices are approved for use in the ship-building industry.EUCHNER joysticks are also used for radio and cable controls, building machinery and cranes.Joysticks as control equipment in remote control devicesDesign and functionMicroswitches with a step function response are used as switching elements. Due to the intermittent control, a clear switching function is given for precise control systems. Depending on the respective application, switching elements with a power rating of between 4mA and 16A can be used. These are fixed on the mounting plate for each different series, either individually or in groups. The switching elements are actuated by the joystick being moved out of the intermediate position. The robust levers made of stainless steel are bedded with a hinged ball bearing that is fixed in a front plate.Advantages/featuresDirection of movement: Simplification of the command control station Easy mounting due to the slots in the panel Small space requirement Long service lifeRobust and lasting constructionHigh potection class: IP 65 and beyondRemote cable control for concrete pumpsModelsEUCHNER joystick switches are available in a number of different models:Series WK...(page 6)Series WE...(page 8)Series KB...(page 10)Series KF ...(page 12)Series KE...(page 14)Series KC...(page 16)Series KP...(page 19)Housing kits (from page 22)suitable for series WK, KB, KE and KFActuatingdirectionsPanel cutoutPushbutton D(with protective cap)Interlock VBellows WClamping screws forpanel thickness (1 - 8 mm)Centre position switch Z (actuated in centre position)Connection D(the connection is located on the under-side for types with 8 directions)Series WK...Control panel installation to IEC 947-5-1 D301 to 8 actuating directions with spring return operation or combinedOne changeover contact with tab connector 2.8 x 0.5 IEC 760 for each actuating direction Centre position switch Pushbutton in handleDimension drawingGermanischer LloydCertificate no. 17 041 - 00 HHOrdering codeSeriesActuating direction and switching behavior Stayput switch S (switching lever latches in selected position)Spring return switch T (switching lever returns to centre position)Options Pushbutton D Bellows W InterlockV Centre position switch Z All-round actuationRW KOrdering examples:Joystick switch series WK, actuating directions 1+3 stayput switch S,WK S13 T24 DZV actuating directions 2+4 spring return switch T, Pushbutton D, centre position switch Z,Interlock V in centre positionJoystick switch series WK, 8 switching elements as spring return switches, all-round actuation R WK T1-8 R DesignJoystick switch series WK, 4 switching elements, 2 actuating directions on request (2 switching elements per actuating direction)* Diagonal actuation of 4 adjacent switching elements is on request.Control panel installation and actuating directionsFront platePushbutton D(with protective cap)Interlock VBellows WConnection Series WE...Control panel installation at rear or with front plate1 to 8 actuating directions with stayput or spring return operation or combined One changeover contact with screw terminal for each actuating direction Centre position switch Pushbutton in handleDimension drawingGermanischer LloydCertificate no. 17 041 - 00 HHOrdering codeSeriesActuating direction and switching behavior Stayput switch S (switching lever latches in selected position)Spring return switch T (switching lever returns to centre position)Options Pushbutton D Bellows W InterlockV Centre position switch Z All-round actuation R Front plate FW EFront plate FOrdering examples:Joystick switch series WE, actuating directions 1+3 stayput switch S,WE S13 T24 DZV actuating directions 2+4 spring return switch T, Pushbutton D, centre position switch Z,Interlock V in centre positionJoystick switch series WE, 8 switching elements as spring return switches, all-round actuation R WE T1-8 R DesignJoystick switch series WE, 4 switching elements, 2 actuating directions on request (2 switching elements per actuating direction)Actuating directionsPanel cutoutInterlock V BellowsSeries KB...Control panel installation to IEC 947-5-1 D301 to 8 actuating directions, 4 switching elements.

欧姆龙液位控制器原理

欧姆龙液位控制器原理

欧姆龙液位控制器原理
欧姆龙液位控制器是一种监测和控制液位的电子设备,其原理是通过测量液位高度,将信号传递给控制器进行逻辑处理,从而实现自动化控制的目的。

该设备采用压力传感器等传感器将液位高度转换为电信号,再经过A/D转换,将数据传递到主控芯片。

主控芯片对数据进行处理,根据预设的逻辑算法输出控制信号,控制执行机构进行操作。

在实际使用中,欧姆龙液位控制器具有多种控制方法,可根据实际需求进行配置。

例如,自动控制模式可以设置目标液位,当液位达到设定值时就停止供液或排液操作;手动控制模式可以手动调节液位高度;报警控制模式可以根据液位高度发出声光报警信号,以提示操作人员或处理异常情况。

综上所述,欧姆龙液位控制器利用传感器监测液位高度并通过逻辑算法实现对液位的自动化控制,可以广泛应用于化工、石油、食品等行业的液位监测和控制。

欧姆龙液位开关说明书

欧姆龙液位开关说明书

开关液位设备概要选择机型的标准故障检查液位设备Q&A关于施工资料参考电极式液位开关(61F)作为电气性液位检测方式,被广泛用于以大厦、集中住宅的上下水道为主及钢铁、食品、化学、药品、半导体等各种工业、农业水、净水场、污水处理等的液面控制。

一旦电极接触到液体,通过液体可以闭合电路(电气流通的道路),根据流过的电流检知液位控制的动作原理,是以所谓的导电性液体为控制对象的液位开关。

进行检测时,直接检测液体的电极间电阻,根据大于或小于已设定的电阻值,来判断有无液面。

■基本原理以一般接收上水道供水的情况为例来进行说明。

通常,在大厦、集中住宅区等中,一旦接水槽接收供水后,就会将水送到设置在屋顶上的高架水槽内,然后再分配到各楼层。

在高架水槽内,如果因水的消耗而导致水槽内的水位下降,通过泵从接水槽中再进行补充。

达到一定的水位后,即可停止泵了。

(参照图1)在高架水槽内,可以进行水位的控制,以保持上限和下限间的水位。

可以根据下列工作原理来进行这一水位控制。

图1. 水槽的供水控制●根据水位对泵进行ON、OFF控制(2根电极式)①如图2,电极E1未接触到液面时,电流流通的电路(E1-E3间)为开路,没有电流通过。

因此,继电器「X」不动作,继电器「X」的接点仍为“b侧”。

②如图3,电极E1接触到液面时,为电路闭合状态(液体将E1-E3间闭合),因此,继电器「X」动作,接点移动到“a侧”。

若将该继电器接点连接到接触器,则可根据液面的位置对泵进行ON、OFF控制。

但是,如图2、图3,如果仅有2根电极,电极E1附近会发生波动,导致继电器抖动。

为此,电极式液位开关有自我保持电路。

(图2、图3用于水位的报警等方面)图2 水位低时图3 水位高时●带自我保持电路的实用性水位控制(3根电极式)如图4所示,使用E1、E3电极以外的E2电极,通过a2接点连接E2、E1。

此时(前页的②)液面接触电极E1、继电器「X」动作,如果接点变为“a侧”,即使接下来液面低于E1,E2-E3间的电路也可以保持闭合状态。

The LD320, LD620, LD621, LD630 offers the advantage of a shorter body than traditional displacement transducers. Furthermore, four electrical output types are provided; these are standard LVDT, 4-20 mA, isolated DC voltage and digital outputs.All models in the LD320, LD620, LD621, LD630 can be configured with guided or unguided core for frictionless operation. The wide bore to core clearance of the LD320, LD620, LD621, LD630 makes installation and alignment a very easy process. The guided versions are provided with polymer bearings for high rigidity and are available with special tips, univer-sal joint fittings and return springs. The universal joints are useful in appli-cations where lever movements induce variations in the motion straight-ness.The rugged construction of the LD320, LD620, LD621, LD630 and the options of IP65 and IP67 rating makes these transducers a cost-effective product suitable for use in harsh environments.GENERAL SPECIFICATIONStorage Temperature LVDT Variants-40 °C to +120 °C 4-20 mA, DC and Digital Variants-20 °C to +85 °COperating Temperature LVDT Variants-40 °C to +120 °C 4-20 mA and DC Variants0 °C to +65 °C Digital variants (Transducer only)-40 °C to +120 CLinearity0.2% FSOFor full specification please refer to the Product Datasheet or catalog.Typical Mechanical Configurations2.1: Mounting the TransducerLVDT based transducers are a reliable and proven technology that iswell established in all areas of manufacturing and control industries.The majority of the associated problems experienced with their appli-cation and use are totally avoidable, particularly if sufficient thought is given during the initial design stages of equipment to the positioning and clamping methods employed for these feedback elements.LVDT’s, being of inductive nature, are susceptible to some degree to theThe LD320, LD620, LD621, LD630, LD650, transducers contain an inte-gral magnetic screen that reduces these effects. However, the transducer should be positioned well away from electric motors, relays and permanent magnets. If this is not possible checks should be made on the influence of such items.Clamping of the coil assembly should be carefully considered. Some example methods are shown below. Ideally the body of the transducers should be clamped centrally in a pinch or yoke type clamp, manufactured from a low conductivity, non-magnetic material.Irrespective of clamping method, care must be taken not to over-tighten retaining screws as distortion of the body may prove damaging to the integrity of the transducer and adversely affect the geometry of the instal-lation.If the LVDT is to be mounted on equipment subject to high ”g” then, dependent on the direction of these forces, it may be advantageous to consider end to end clamping in preference to over body clamping.For Universal Joint fittings maximum tightening torque on the ball = 2.5 Nm.2.2: CoresThe standard core supplied is a ∅6.35 mm Core with M4 x 0.7 x 12 mm female thread at both ends for mounting onto a carrier. The magnetic core has been manufactured to achieve optimum performance and any sub-sequent handling of the core which results in stress being imparted will render the calibration void. This includes over-tightening of the core during installation onto its carrier. Hand tightening and retention by meansof a suitable thread locking anaerobic retaineris the recommended procedure.2.3: CarriersA standard length carrier is available for each model of transducer, manu-factured from 316 stainless steel and incorporating an M4 x 0.7 x 10 mm long male thread for attachment to the standard core and an M6 x 1.0 x 17 mm male thread for attachment to the fixture.2.3.1: Guided CarriersMounting: Normal mounting methods apply (see Installation). Careful con-sideration should be given to alignment; the carrier must be able to move freely within the transducer core. Side force should be kept to a minimal level.Maintenance: Check for free movement of the carrier when in the vertical plane. The polymer guide bearing is maintenance free.2.3.2: Ball TipsThis option is for use with the Guided Carrier andis attached via an adapter fitted to the threaded end of the core carrier. Side forces that may exert undue pressure and flex the carrier must be avoided.2.3.3: SpringsA spring may be fitted externally in conjunction with a guided carrier and also with a ball tip.2.3.4: Universal JointsMounting: All LD320, LD620, LD621, LD630 transducers up to 300 mm total measurement range (±150 mm) may be mounted in any axis; it is recommended that the rear rod end bearing (near cable exit) is mounted on the static component. (The larger transducers, because of the increase in weight, may exhibit bowing of the carrier and therefore mounting in the horizontal plane should either be avoided or additional support given to the body. This option is used with the guided core.)Maintenance: Periodic inspection of locking screws and nuts etc. is advis-able depending upon the Customer’s application. Rod end bearings should be able to move freely and have minimal side play.2.3.5: Thread Mount Option - LD650 Series3.0: Electrical Interfaces3.1: Standard LVDT The LD320, LVDT output transducer is designed to operate with an exci-tation voltage of 3 ± 1 V rms, an excitation frequency of 5 ± 0.5 kHz into a 100 k Ω load as detailed below. Operation in different configurations may mean the optimum performance is degraded.Standard LVDT Connector 5 pin 240º DINThe LD320 range of LVDT transducers operate on the principal that move-ment of a core inside the transducer body is detected by a differential change in output on two secondary coils, the primary coil(s) being energized by an appropriate AC excitation signal. With the core in a central position, the coupling from the primary to each secondary is equal and opposite and therefore cancel out, thus the resultant output voltage is zero. As the core is displaced further into one secondary, its voltage increases proportionally and the other secondary voltage decreases hence the output changes in magnitude and phase in proportion to movement in either direction from null.The red and white connections are in phase for inward movement (i.e. towards the cable end).The output signal depends on both core movement and energization voltage and is expressed as a sensitivity in mV output / V energizing/ mm travel.White 3.2: 4-20 MA The LD630 and LD650 are configured as a two wire 4-20 mA loop device, the transducer provides a current between 4 mA (fully out) and 20 mA (fully in). The transducer requires an excitation voltage between 10 VDC Note: 4-20 mA products are designed to operate with a maximum loop resistance of 600 W.3.3: DC Voltage The LD620 and LD621 can be configured to provide a DC voltage output as shown below;Measurement RangeOutput Output 0-d mm0-10 VDC -d/2 to +d/2 mm -5 VDCto +5 VDCThe transducer requires an excitation voltage between 10 VDC and 30 VDC.The transducer output is electrically isolated from the input supply.Note: to achieve calibrated accuracy the load must be 10 k W between Yellow and Green,3.4: DIGITAL Digital versions of the LD640 transducers are supplied with an integral PIE module.This module is fully compatible with LDN232. For details see Digital Probe User Leaflet.3.0: Electrical Interfaces (continued)4.0: ConditioningThe 4-20 mA and DC output version of the transducer require no signal conditioning other than being connected to an appropriate receiver such as a voltmeter, A/D converter or current meter.LVDT transducers usually require the signal to be conditioned either by end user amplifiers or with Omega conditioning circuits.

开关液位设备概要选择机型的标准故障检查液位设备Q&A关于施工资料参考电极式液位开关(61F)作为电气性液位检测方式,被广泛用于以大厦、集中住宅的上下水道为主及钢铁、食品、化学、药品、半导体等各种工业、农业水、净水场、污水处理等的液面控制。

一旦电极接触到液体,通过液体可以闭合电路(电气流通的道路),根据流过的电流检知液位控制的动作原理,是以所谓的导电性液体为控制对象的液位开关。

进行检测时,直接检测液体的电极间电阻,根据大于或小于已设定的电阻值,来判断有无液面。

■基本原理以一般接收上水道供水的情况为例来进行说明。

通常,在大厦、集中住宅区等中,一旦接水槽接收供水后,就会将水送到设置在屋顶上的高架水槽内,然后再分配到各楼层。

在高架水槽内,如果因水的消耗而导致水槽内的水位下降,通过泵从接水槽中再进行补充。

达到一定的水位后,即可停止泵了。

(参照图1)在高架水槽内,可以进行水位的控制,以保持上限和下限间的水位。

可以根据下列工作原理来进行这一水位控制。

图1. 水槽的供水控制●根据水位对泵进行ON、OFF控制(2根电极式)①如图2,电极E1未接触到液面时,电流流通的电路(E1-E3间)为开路,没有电流通过。

因此,继电器「X」不动作,继电器「X」的接点仍为“b侧”。

②如图3,电极E1接触到液面时,为电路闭合状态(液体将E1-E3间闭合),因此,继电器「X」动作,接点移动到“a侧”。

若将该继电器接点连接到接触器,则可根据液面的位置对泵进行ON、OFF控制。

但是,如图2、图3,如果仅有2根电极,电极E1附近会发生波动,导致继电器抖动。

为此,电极式液位开关有自我保持电路。

(图2、图3用于水位的报警等方面)图2 水位低时图3 水位高时●带自我保持电路的实用性水位控制(3根电极式)如图4所示,使用E1、E3电极以外的E2电极,通过a2接点连接E2、E1。

此时(前页的②)液面接触电极E1、继电器「X」动作,如果接点变为“a侧”,即使接下来液面低于E1,E2-E3间的电路也可以保持闭合状态。

这种E2电极和接点构成的电路称为自我保持电路。

如果液面低于E2,为使电路再次打开、继电器「X」复位到“b侧”,可以在E1-E2间对继电器[X]进行ON、OFF控制。

图5表示该动作的时间图。

由于这种动作方式简单,除了液位控制,电极式液位开关还应用于接触开关、漏水检测器、进行大小判别的传感器等。

图4 自我保持电路图5时间图请注意:在油之类不能通电的液体中,不能根据本方式进行液面控制。

●净水用于饮用的净化水,一般指送到家庭的水、自来水。

使用泵送到指定地方的水。

多为抽取自来水。

而净化槽,是指净化污水的槽,不要混淆。

●使用水有目的地储放的水,多为与自来水有相同灵敏度的水。

如防火用水等。

. ●污水是流向下水道前的水,一般指厕所的排水。

[参考]家庭、工厂的排水中含有固体物、浮游物,且液体也是低电阻,因此必须考虑电极的设置。

●上水(自来水)[参考]基本上与净水的意思相同。

对下水来说是上水,在水道局也有上水道和下水道之分。

在水道局,净化前的水也称为上水,比净水意思更广。

●下水(下水道)与其说是水的种类,还不如说是污水流动的体系。

发达国家的下水道是很完善的。

在一些大城市,下水道完善的地方较多,这种情况下,无需净化槽,直接流出污水排杂槽。

另外,也有一些地方没有设置污水排杂槽,而往往会直接将流出污水的管子连接到下水道。

●雨水61F-GN-NH3指积留在水坑等地方的雨水。

与净水相比,电阻稍高。

●涌出水指像泉水一样涌出的水。

●循环水与雨水相同,电阻稍高●抽水使用泵送到指定地方的水。

多为抽取自来水。

●使用水有目的地储放的水,多为与自来水有相同灵敏度的水。

如防火用水等。

●离子交换水是指除去离子成分的水。

除去离子成分的方法不是蒸馏,因此是高电阻。

[参考]一般使用的水为动作电阻200kΩ更有时使用61F-GP-NH3 ,但使用除去离子成分的方法后,电阻值会提高。

(纯水)●蒸馏水一般为收集的水蒸汽,但电阻比纯水低。

[参考]可以用高灵敏度用的61F。

●循环水锅炉蒸汽的循环水。

在管道中,指蒸汽成为水滴形成的水。

●纯水指不含不纯物质的水。

事例如下,从200kΩ·cm开始,高达18MΩ·cm位,必须使用超高灵敏度的61F 。

[参考]为纯水时,为确保水的纯度,应使用钛电极。

●冷凝水指蒸汽涡轮、锅炉等的冷却水。

指为使锅炉的热水保持一定的纯度而排放出来的水。

用于存放这种水的容器,其电阻应比一般用的稍低。

水槽·池●接水槽在大厦、公寓大楼等高层住宅屋顶上有高架水槽的地方,一旦水槽里储有水,就会在高架水槽内用泵将水吸上来。

这个水槽称为接水的水槽。

一般设置在地下室或一层。

[参考]在本样本目录中作为一般性的供水源,但在大厦以外的情况下不称为接水槽。

它多与消防用的消防栓共用,选择电极的长度时必须考虑这些。

接水槽本身的液位控制,通过另外的61F 或球形旋塞来进行。

(也有和高架水槽用的61F的电极一起接入的情况)在稍微大点的大厦、公寓大楼中使用61F-G4N。

●高架水槽指设置在大厦、公寓大楼等高层住宅屋顶上的,利用高度来提供水槽。

[参考]从接水槽61F-G4N或61F-GIN 等自动地将水泵上来。

最近引进了直接施加压力进行送水的系统(压送式),也可用于?不带高架水槽的大厦,在停电、天灾等情况下,人们重新认识了储水罐的作用。

指相对于水源地,将从水源地分配到的暂时性蓄水,提供到住宅的池。

设于分支用的小型水源地。

●污水排杂槽在下水道完善的城市中,作为净化水槽的替代品,积蓄来自厕所的污水和厨房的排水。

[参考]对于普通的公寓大楼等,是从污水管道直接流到下水道,但是对于有地下室的大楼,必须到下水道用泵将水吸上来。

为此,必须在地下设置积蓄污水的槽。

此时,油、固体物会直接进入,因此,设置电极时,必须每隔1 极设置,并防止电极间的短路。

●水源池指水道局为给居民用的水道供水而造的池等。

无论何种形式下,从各种水源将水送到这里,通过净化装置为市民供水。

[参考]水源池通常应保持一定的水位,多使用61F,继电器和电极间的布线非常长的地方也有很多。

除公共场所以外,也有一些私设水源地的地方●净化槽收集厕所的排水,暂且在这里进行净化。

即在无固体物的状态下将其排放到其他地方。

[参考]由于净化槽中环境为弱碱,因此必须注意绝缘。

在下水道完善的城市,大厦等无需净化槽的地方也较多,而将其转移到污水排杂槽。

规格●动作电阻指61F本体进行动作所需的电极间的电阻值,如果液体或固体的电极间电阻值低于该值,就一定会动作。

[参考]即使在该值很高不易导通的液体中,也能动作,这时需要高灵敏度。

●电极间电阻大致与动作电阻相同。

从61F的输入(电极)到61F本体有动作电阻、布线有可能是长距离,因此不一定相同,但一般情况下认为是相同也是没问题的。

●导电率(西门子:S)表示液体导电度的单位。

最近用微西门子(μS)来表示(以前是姆欧:)。

由于是电阻的倒数,值越小电阻就会变得越高,因此必须为高灵敏度。

1μS/cm →1MΩ·cm2μS/cm → 500kΩ·cm10μS/cm → 100kΩ·cm●自我保持如果继电器工作,记忆保持这一状态的功能就是自我保持。

为61F-GN时,E2电极就会变为自我保持用。

根据具备的自我保持功能考虑控制的幅度,另外,可防止由于液面的波动引起的继电器抖动。

●接点容量(输出)61F可开关负载容量。

●复位电阻61F本体进行复位所需的电极间的电阻值,如果高出该值,61F就会复位。

[参考]一般情况下,如果没有液体,电阻将会变为无穷大,但是,由于电极保持器、分离器等上面附着了液体,因此不能马上变为无穷大。

61F中,多数情况下该值较为重要(根据布线的不同,还会影响到漏电流),低灵敏度用、远距离用就是因为这一原因。

●固有电阻表示液体电流流动的难易度,单位为kΩ·cm.为电导率成倒数的关系。

(请注意,与动作电阻不同)通过液体使电气在电极棒间的无数线路流通。

固有电阻表示这一电气流通的难易度。

由于固有电阻根据电极的设置条件、浸水长度而有所不同,因此,实际设备的动作是根据电极的间隔、表面积(浸水长度)确定的。

要求出电极间电阻较困难,因此以固有电阻为标准。

●动作电压指61F动作所需的电源电压。

61F的动作电压为额定电压的85%以上。

因此,注意不要使电源电压在85%以下。

●最小适用负载电子电路等非常小的负载(微小负载)的可开关界限的标准。

●接点构成指接点的接触机构。

[参考]●负载分为以下3种⑴阻性负载指如果施加电压,就会一直流通相同值电流的负载,如加热器。

⑵感性负载指含有电感的负载,如电机、螺线管等。

⑶容性负载指含有电抗的负载,如电容器等。

[参考]●冲击电流闭合接点的瞬间,大于稳定状态的过渡性流入电流。

●预动作方式61F 本体施加控制电源的同时,内置继电器动作,电极间流入电流就会复位的方式。

●正动作方式在电极间流入电流后,内置继电器进行动作的方式。

注. 高灵敏度以外采用正动作方式。

但61F-G□NH也采用正动作方式●开关频度单位时间的动作次数。

如,次/hour 。

动作●2线式(带R)电极和61F本体间,可以省略1根电线进行布线的方式,液位电极、自我保持电极、接地电极3线当中,省略自我保持电极进行布线的方式。

而自我保持电极是必须的。

这种情况下,必须选择型号中带R型的61F 本体(继电器单元也一样)、电极保持器,并加上(电阻)1W 6.8kΩ。

[参考]*1. 表示兼具防止泵空转的供水自动运转。

*2. 表示兼具异常缺水报警的供水自动运转时。

●3线式相对于2线式的称呼。

(61F的基本方式为3线式)●防止空转用泵将水吸上来时,在大厦、公寓大楼等高层大楼中,可以通过接水槽吸到高架水槽中。

此时,如果接水槽内没有了水,并继续空转,则会吸进空气,可能会导致电机过热并烧损。

为了避免这种情况,必须在水位降到一定液位以下时,将泵强制停止,即可防止马达烧损。

61F-G1N 、-G1 以及61F-G4N 、-G4 均具备该功能。

●交互运转用电机将水吸上来时,在达到某种规模的地方,备有预备电机。

如果不使用电机,可能会导致其生锈老化;而如果连续使用,其产生的热量也会导致其老化,因此,通过2台电机交互使用,就会延长电机的使用寿命,即使1台出了故障,还有1台也可以运转。

[参考] (必须配备外部切换开关)61F-AN 、-APN2带有该功能。

选择机型的标准■分类(供参考用)●根据液体来分类的示例●根据电极部安装来分类的示例●根据电极部安装来分类的示例■选择61F本体的标准●固有电阻和机型选择的标准使用一般用途的可控制液体的固有电阻时,用PS-3S电极保持器、浸水长度为30mm以下的情况下,其界限为30kΩ·cm。
