传感器使用说明书

传感器使用说明书

传感器使用说明书传感器概述传感器是按一定规律实现信号检测并将被测量(物理的、化学的和生物的信息)变换为另一种物理量(通常是电量)的器件或仪表。

它既能把非电量变换为电量,也能实现电量之间或非电量之间的互相转换。

换句话说,一切获取信息的仪表器件都可称为传感器。

传感器是自动控制系统必不可少的关键部分。

所有的自动化仪表和装置均需要先经过信息检测才能实现信息的转换、处理和显示,然后达到调节、控制的目的。

离开了传感器,自动化仪表和装置就无法实现其功能。

在国际上,传感技术被列为六大核心技术(计算机、激光、通信、半导体、超导和传感)之一,传感技术也是现代信息技术的三大基础(传感技术、通信技术、计算机技术)之一。

传感器一般由敏感元件、转换元件、基本转换电路三部分组成.传感器是将机电一体化产品中被检对象的各种物理变化量变为电信号的一种变换器。

它被用于检测系统自身和作业对象、作业环境的状态,为有效地控制机电一体化产品的动作提供信息。

传感器的种类繁多,按其作用可分为检测机电一体化产品内部状态的内部信息传感器和检测作业对象和外部环境状态的外部信息传感器。

内部信息传感器包括检测位置、速度、力、转矩、温度以及异常变化的传感器。

而外部信息传感器有与人体五感相对应的,也有纯工程性的。

与五感相对应的有接触式的(压觉传感器、滑动觉传感器等)和非接触式的(视觉、听觉传感器等)。

纯工程性的是人体感官所不及的,如电涡流传感器、无线电接收机、超声波测距仪、激光测距仪等。

按输出信号的性质可将传感器划分为开关型(二值型)、模拟型和数字型。

技术参数(1)额定载荷:传感器的额定载荷是指在设计此传感器时,在规定技术指标范围内能够测量的最大负荷。

但实际使用时,一般只用额定量程的2/3~1/3。

(2)灵敏度/额定输出:加额定载荷时和无载荷时,传感器输出信号的差值。

由于传感器的输出信号与所加的激励电压有关,所以灵敏度的以单位mV/V来表示。

(3)灵敏度允差:传感器实际稳定输出对应的标称灵敏度之差对该标称灵敏度的百分比。

Dwyer Instruments L-FCLS 流动级别传感器说明书

SPECIFICATIONSService: Liquids, powder, and bulk materials compatible with wetted materials. Wetted Materials:304 SS.Insulated Materials: PTFE.Temperature Limits:Ambient: -4 to 140°F (-20 to 60°C);Process: -4 to 176°F (-20 to 80°C).Pressure Limit: 285 psi (19.7 bar).Power Requirements: 110 or 220 VAC.Power Consumption: 2 W.Enclosure: Aluminum, painted.Enclosure Rating: IP65.Switch Type: SPDT.Electrical Rating: 3 A @ 250 VAC.Electrical Connections: Screw terminals. Conduit Connection: 2 x 1/2˝ female NPT.Process Connection: 2.5˝ - x 5 kg/cm 2JIS flange.Mounting Orientation: Side mount. Fail Safe: Selectable fail high or fail low. Adjustable Sensitivity: 1 to 20 pF.Time Delay: 0 to 6 seconds.Weight: 7.1 lb (3.2 kg).The Model FCLS Flush Capacitance Level Switch is ideal for level measurement of liquids and bulk solids to trigger an alarm or close a filler inlet. No probe design allows for installation where space is constrained or where material flow or material build up would damage a probe. With no moving parts, this level switch assures no jams, no wear, nothing to break, and no maintenance. Comes standard with IP65 housing with a maximum pressure limit of 285 psi (19.7 bar).Coarse CalibrationTo calibrate the coarse adjustment of the FCLS, the following steps should be followed:1. Set the sensitivity adjustment to the H position.2. Using a screw driver, adjust the coarse sensitivity until the indicator lamp turns on.3. Check to see if indicator lamp turns on when adjusting the sensitivity knob. If not,repeat procedure.Sensitivity AdjustmentTo adjust the sensitivity of the FCLS, the following procedure should be followed:1. When the material is detected by the level switch, the indicator lamp will illuminate. Otherwise, it will remain off.2. While the level switch is detecting the material, adjust the sensitivity knob until the indicator lamp turns off.3. Set the sensitivity adjustment knob in the middle position between where the indicator lamp turns on and where it turns off.4-3/8Figure ATime Delay SelectionThe time delay is the programmed time between when the surface senses the presence or absence of materials and when the relay changes state. A time delay is good for applications that could have false or rapid pulsing of level indications from sloshing or agitated material. Choose a delay setting appropriate for the specific application. The default delay setting is set at 0 seconds. The maximum time delay is 6 seconds. To increase the delay time from zero, turn the TIME DELAY potentiometer clockwise (see Fig. A).MOUNTINGThe FCLS should be horizontally mounted. The mounting wall thickness should not exceed 0.98˝ (25 mm).FAIL SAFE SELECTIONFSH ModeFail-Safe High means that the relay will be energized when the sensing surface is uncovered by the material (SIGNAL LED is on) and will de-energize with the sensing surface is covered (SIGNAL LED is off). In this mode, a power failure will cause the relay to de-energize like the surface is covered.FSL ModeFail-Safe Low means that the relay will be de-energized when the sensing surface is uncovered (SIGNAL LED is off) and will energize with the probe is covered (SIGNAL LED is on). In this mode, a power failure will cause the relay to de-energize like the surface is uncovered.MAINTENANCE/REPAIRUpon final installation of the Model FCLS no routine maintenance is required. The Model FCLS is not field serviceable and should be returned if repair is needed. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sales” in our catalog and on our website. Contact customer service to receive a Return Goods Authorization number before shipping the product back for repair. Be sure to include a brief description of the problem plus any additional application notes.©Copyright 2014 Dwyer Instruments, Inc.Printed in U.S.A. 7/14FR# R6-444064-00 Rev. 5。

LBV301Vibrating level switch Rugged, flexible and cleanable P r o d u c t i n f o r m a t i o nf L u i d s e n s o r s | s i c K8014462/2011-09-05Subject to change without notice2Product descriptionThe LBV family of level sensors features a vibrating fork sensor that provides overfill or dry-run signals for containers with bulk or powdered materials. The reli -able and accurate LBV301 level sensors signal full, empty, or demand states. The rugged, stainless steel sensor design prevents bulk materials from jamming. When the probe is covered with bulk ma -terial, the changing vibration amplitude is reliably detected and converted into a switching signal. In addition, the LBV301 features an easy-to-clean monoprobethat is immune to contamination, making it suitable for use in the food industry. While the LBV311 base version is mainly mounted horizontally, the LBV321 with a suspension cable and the LBV331 with a tube extension are mounted vertically to bridge switching distances of up to 80 m or 6 m respectively. With a variety of process connections for hygienic applica -tions, and several output options, the LBV301 can be used for nearly all appli -cations, even in explosive atmospheres.at a glance•Compact

The instru-ment only has to be mounted in such a way that the vibrating element is at the height of the desired switching point.The only exception is vertical mounting of the tuning fork from below. In this position there is the danger of solid particles get-ting stuck between the fork tines.socketThe vibrating element should protrude into the vessel to avoid build-up. For that reason, avoid using mounting bosses for flanges and screwed fittings. This applies particularly to horizon-tal installation and use with adhesive products.filling openingInstall the instrument in such a way that the vibrating ele-ment does not protrude directly into the filling stream. Should such an installation location be necessary, mount a suitable baffle above or in front of the vibrating element, e.g. L80 x8 DIN 1028 (see Fig. Part …a.“). In abrasive solids, mounting according to fig. Part …b.“ has proven to be a good solution. The mound that forms in the concave baffle protects it from abrasion.a. Convex mountingb. Concave mountinginflowing mediumIf LBV301 is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount LBV301 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur.Horizontal mountingTo achieve a very precise switching point, you can installLBV301 horizontally. However, if the switching point can have a tolerance of a few centimeters, we recommend mounting LBV301 approx. 20° inclined to the vessel bottom to avoid build-up. Orient the tuning fork of LBV301 so that the product cannot remain lying on the fork surface. There is a mark on the thread hexagon for aligning the fork. Make sure that the mark points upward. material coneTo achieve a very precise switching point, you can install LBV301 horizontally. However, if the switching point can have a tolerance of a few centimeters, we recommend mounting LBV301 approx. 20° inclined to the vessel bottom to avoid build-up.Orient the tuning fork of LBV301 so that the product cannot remain lying on the fork surface. There is a mark on the thread hexagon for aligning the fork. Make sure that the mark points upward.To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall.1 LBV3212 Emptying opening3 Filling openingf L u i d s e n s o r s | s i c K8014462/2011-09-05Subject to change without notice14tensile loadWith cable version, make sure that the max. permissible tensile load on the suspension cable is not exceeded. The danger of this happening exists particularly with very heavy solids and large meas. lengths. The max. permissible load is stated in chapter …Technical data“.agitatorsDue to filling or extraction forces, vibrations or similar, the level switch can be subjected to strong lateral forces. For this reason, do not use an overly long extension tube for LBV331, but check if a LBV311 level switch couldn‘t be used instead, mounted on the side of the vessel in horizontal position. Extreme vibration caused by the process or the equIP ment, e.g. by fluidization or beaters in the vessel, can cause theextension tube of LBV301 to vibrate in resonance. This leads to increased stress on the upper weld joint. Should a longer tube version be necessary, you can provide a suitable support or guy directly above the vibrating element to secure the extension tube.This measure applies mainly to applications in Ex areas. Make sure that the tube is not subject to bending stress due to this measure.If an installation from above is necessary, check if you can use a cable version. Over a longer period of time, strong vibration can damage the instrument electronics. You can decouple the electronics from the process by using a remote (displaced) housing.Baffle protection against falling rocksIn applications such as grit chambers or settling basins for coarse sediments, the vibrating element must be protected against damage with a suitable baffle.t i t L e|s i c K 8014462/2011-09-05Subject to change without notice 15Search online quickly and safely with the SICK “Finders”Efficiency – with SICK e-commerce toolsfind out prices and availabilityDetermine the price and possible delivery date of yourdesired product simply and quickly.Request or view a quoteYou can have a quote generated online here.Every quote is confirmed to you via e-mail.order onlineYou can go through the ordering process in just a fewsteps.Product finder: We can help you to quickly target the pro-duct that best matches your application.applications finder: Select the application description onthe basis of the challenge posed, industrial sector, or pro-duct group.Literature finder: Go directly to the operating instructions,technical information, and other literature on all aspectsof SICK products.These and other Finders at ProductServiceclearly structured: You can findeverything you need for your sensorplanning under the menu items Pro-ducts, Information, and My Account.available 24 hours a day: Regard-less of where you are in the world orwhat you’d like to know – everythingis just a click away at www.mysick.com.safe: Your data is password-pro-tected and only visible to you.

L S B传感器说明书 This model paper was revised by the StandardizationOffice on December 10, 2020LS1206B型旋桨式流速仪使用说明书潍坊金水华禹信息科技有限公司目录1 主要用途及适用范围LS1206B型旋桨式流速仪是一种在水文测验中进行流速测量的常规通用型仪器,用于江河、湖泊、水库、水渠等过水断面中预定测点的时段平均流速的测量,亦可用于压力管道以及某些科学实验中进行流速测量。

LS1206B型旋桨式流速仪符合GB/T11826-2002《转子式流速仪》等相关国家标准。

LS1206B型旋桨式流速仪广泛适用于水文测验、水利调查、农田灌溉、径流实验等,亦可适用于水电、环保、矿山、交通、地质、科研院所、市政等行业或部门进行相关流速或流量的监测。

2 主要技术性能及参数1)旋桨回转直径:Φ70mm2)旋桨水力螺距b:120mm(理论值):0.05m/s3)起转速度v4)临界速度v:约0.13m/sk(以实际检定值为准。

据统计分析,v k远小于上述值。

)5)测速范围:0.07m/s~7m/s6)输出信号:磁激式开关接点通断信号7)信号数/转子转数:2/1(每转2个信号)8)开关接点容量:DC U≤24VI≤120mA9)接点工作次数:1×107时)10)全线相对均方差m:|m|≤1.5%(用于v≥vk11)相对误差δ:|δ|≤5%(用于v<vk 时)12)工作水体环境:水温0℃~+40℃水深0.1m~30m悬移质含沙量≤20kg/m313)贮存环境:温度-25℃~+55℃湿度≤90%3 结构特征与工作原理LS1206B型旋桨式流速仪由旋桨、旋转部件、支座、尾翼部件(或固杆螺丝)、干簧管部件等组成(参见图1)。

旋桨用于被动感受水流,在水流驱动作用力下,绕水平支承轴旋转。

其回转直径为Φ70mm,理论水力螺距(机械导程)为120mm。

旋转部件(参见图2)由壳体及其内部的转子系统(旋转支部件,参见图3)、动套支部件和压帽等组成。

用于在旋桨推动作用力下,产生一定的角速度,并激励干簧管产生通断信号。

支座用于流速仪工作时的安装和固定,其安装孔径为Φ16mm。

尾翼部件(产品选配件)用于流速仪工作时的定向。

干簧管部件用于接受来自转子系统的磁激励,对外提供流速仪信号。

流速仪工作时,旋桨受水流驱动产生回转,带动旋转部件的转子部分同步旋转,安装在转子上的磁钢激励干簧管产生通断信号。

4 安装(1)测杆安装浅水测流时,可选用CG16-1型测杆(产品选配件)(参见图4)安装。

测杆总长1.6m,每节0.4m;测杆上每2cm有一道刻线,每10cm有数字标识,作为测深和流速仪安装位置的标志。

测杆上方有指针(方向标)以使流速仪对准流向(方向标在测杆上的位置应高于水面,以方便找准和观察)。

在确认方向标与流速仪指向一致,并可以目测对准流向时,可不安装尾翼部件。

(2)悬杆、悬索安装测点相对较深时,一般采用悬吊法测流,流速仪安装于悬杆、悬索或铅鱼上。

这种情况下,可根据实际需要确定是否安装尾翼。

5 使用、操作及维护流速仪的使用应严格按照SL443-2009《水文缆道测验规范》、GB50179-93《河流流量测验规范》及其它相关水文测验规范的有关规定执行。

5.1 使用前的准备流速仪入水使用前,应进行以下简单测试:(1)灵敏度测试1)对准旋桨迎水面轻缓而均匀地吹气,旋桨应能轻松起转,无卡顿现象;该项测试在很大程度上取决于使用者的实际经验,应反复测试,熟练掌握,以便今后有所比较。

2)用手快速拨转旋桨,应无急停现象。

(2)信号测试使用计数器或音响器、万用表等进行测试,信号应准确、可靠。

5.2 流速与转子速率的关系在临界速度v k 以上,水流速度(通常指某测点的时段平均流速)与流速仪转子速率之间存在一个比较稳定的线性关系。

在确保精度的前提下,LS1206B 型旋桨式流速仪在其测速范围内提供以下统一关系式:bn a v +=(1) 式中: v —流速(时段平均流速),m/sa —流速仪常数,m/sb —旋桨水力螺距,mn —流速仪转子速率,s -1T R n /=(2) 式中: R —流速仪转子总转数T —测速历时,s为消除水流脉动对测量精度的影响,根据水文测验规范的要求,一般T ≥100s 。

对于LS1206B 型旋桨式流速仪,转子每旋转一周,流速仪产生2个信号,因此公式(1)有如下表述:TN b a v 2+= (3) 式中: N —测速历时内总信号数公式(3)中a 、b 值的确定,由专门的流速仪检定机构通过水槽检定(参见GB/T21699-2008《直线明槽中的转子式流速仪检定/校准方法》)后给出,并出具检定证书。

对于不同的流速仪个体,其值各不相同。

流速仪出厂前,检定证书随机发出。

用户在使用流速仪前,可从检定证书中查出该台流速仪的相应a 、b 值。

由上述可知,用户只需测出总信号数及对应的测速历时,便可计算出该时段内某测点的平均流速。

5.3 使用、操作及注意事项流速仪一般需与合适的计数器一起使用。

根据信号数与转子转数的比例,低速测量时亦可采用人工计数(如音响器与秒表配合使用)。

使用流速仪计数器可自动测算流速,方便快捷。

使用过程中应注意以下事项:(1)入水前,裸露的信号接线处应用绝缘胶布或胶带裹紧,以免水体成为信号介质;(2)信号线的接入方法请参见图4;(3)入水前,应检查流速仪安装各环节是否稳固;(4)流速仪提出水面时,为防止可能发生的旋桨松脱现象,不可使旋桨迎水面背离流向(流速较大时尤其注意)。

5.4 维护、保养及注意事项LS1206B型旋桨式流速仪内部结构精密,维护和保养工作需做的精细一些。

应做好以下几点:(1)每次使用后应用清洁的软布(或毛巾)将流速仪表面残留的水珠、污物等擦拭干净,按原状装回仪器箱。

(2)避免流速仪受到碰撞,尤其是旋桨在受到不适当的外力作用时可能会产生变形甚至断裂,从而影响其正常使用。

(3)汛期前,应对流速仪进行一次全面的检查:1)干簧管部件(参见图1)为易损件(以每年测流总时长200h,平均流速0.5m/s计,那么干簧管每年工作次数为6×106),为确保流速仪正常工作,应检查其信号是否可靠,必要时需更换干簧管部件。

干簧管部件的更换工作极其简单,只需从支座上直接旋下就可以了(参见图1);这项工作甚至可以在水面以下进行,而无需将流速仪提出水面。

2)根据相关标准规定,球轴承结构的流速仪应每隔6个月检查并加油一次。

LS1206B型旋桨式流速仪具有良好的油室密封性能,防进水(沙)能力较强,可根据当地水文特性及使用情况酌情增减清洗和加油的频次。

以下为清洗、加油操作过程,供参考:a.拆卸流速仪:需要清洗的部分主要是轴承及密封部分(参见图3,旋转支部件)。

将旋转部件从支座上旋下,从压帽处观察内部仪表油质量。

若油质清晰、含水量极少,旋转灵活,可不拆洗;反之,则应拆卸清洗。

首先,从旋转部件上旋下压帽(参见图2);然后,借助钩形扳手及小改针(产品附件)旋下动套支部件(小改针穿入支承轴前端的径向孔内,钩形扳手的前端小钉插入动套支部件的其中一个径向孔,用拆卸正常右旋螺纹的方法操作即可);再从壳体中退出整个旋转支部件。

部分流速仪产品在动套支部件与旋转支部件间可能会有一个极小的补偿垫圈(为补偿加工误差而设,其尺寸为:外径Φ6.2mm、内径Φ5mm、厚度约0.3mm)。

拆卸动套支部件后应十分注意,小心弄丢。

清洗完毕重新装配时,应先将补偿垫圈从支承轴前端放入,然后装配动套支部件。

b.准备一定量的高标号清洁汽油(推荐使用120#航空汽油),倒入一容器内。

1.容器体积应能适合将旋转支部件水平放入;2.为尽量避免零、部件受到汽油内沉淀杂质的二次污染,清洗时容器内最好设一漏网隔层。

c.将壳体、旋转支部件等置于汽油内洗涤。

其中轴承的洗涤,应使其内、外圈间做相对高速旋转。

d.若轴承旋转灵活性欠佳,应将旋转支部件(参见图3)拆分(旋下并帽部件即可),再单独清洗轴承(在汽油中,捏住轴承内圈后快速拨转其外圈)。

必要时应更换新的轴承。

建议使用D级精度以上的轴承,且不可带防尘圈。

e.清洗完毕沥干后,将各件按序重新装配好。

旋入压帽前,应往压帽内注满仪表油(产品附件,出厂前标准配置约30ml)。

1.仪表油请选用低运动粘度(50℃下约6~10mm2/s)、不含水分和机械杂质、具有良好的抗氧化能力、良好的化学稳定性和光安定性的产品;2.仪表油用后,应盖紧瓶盖,以防灰尘及杂质的侵入。

f.检验旋转部件的旋转性能。

g.用清洁的软布擦拭干净,置于仪器箱内待用。

(4)根据有关规定,流速仪在正常使用条件下,公式(1)的稳定有效期为1年。

使用1年后,或未满1年但其累计工作时间已满300h的,应当送流速仪检定机构重新检定,核准a、b值。

LS1206B型旋桨式流速仪具有较好的密封性能;旋桨材料抗老化性能、耐蚀性能、耐冲击性能等优异,并具有极好的尺寸稳定性。

因此,若流速仪维护得当、按规定做好清洗和加油工作,可在条件许可的情况下(如:与其它流速仪作现场比测,误差在规定范围),适当延长公式(1)的使用期限。

但根据规定,公式(1)的最长稳定有效期不得超过2年。
