Should you require further assistance,please contact your +GF + SIGNET dealer.1.1 DescriptionThe +GF + SIGNET 8800 Conductivity system is used in conjunction with an insertion type sensor that continuously measures the conductivity (total dissolved solids or gases) of a solution in a wide variety of process applications.The Conductivity Transmitter consists of aconductivity sensor and an electronics package (transmitter). The electronics package is housed in a NEMA 4X/IP65 enclosure.The +GF + SIGNET 8800 transmitter system can be converted for submersible applications such as water wells, tanks etc. Optional submersion kit,p/n 3-2700.391 includes the necessary parts and assembly instructions for extending the sensor length up to 12 ft. The submersible kit requires a 3/4 inch pipe with male NPT threads on both ends, (user supplied) that is used to physically extend the sensors' length.1The submersion kit also requires an extended cable, (purchased separately) which is used to interface the sensor to the electronics. Optional extension cable p/n 3-8800.261-XX (-03, -06, -09 or -12 ft.). Refer to Figure 1 below:2Figure 1 Transmitter submersion kit and required extension cable.Chapter 2Calibration2.1 Wet CalibrationYour 8800 Conductivity transmitter has been electronically calibrated at the factory before shipment. You will need to perform a wetcalibration to compensate for electrode variations.Wet calibration compares the output of thetransmitter against the conductivity value of a test solution.Wet Calibration should be performed while the 8800 Conductivity transmitter is beingpermanently installed. When done carefully, you can trim the transmitter accuracy to within ±1% of full scale.3Figure 2Adjustment pots and connectorsEquipment Required• Small screwdriver• Power supply (10 to 30 VDC)• Ammeter2.2 Calibration Procedure1.Connect power supply to transmitter input placing an ammeter in series with the input power, see Figure 3.4Figure 3Transmitter Hook-up2.With the Conductivity electrode in the air (0 conductance) adjust the Zero pot (R26) for 4.00 mA.3.Place the electrode into a solution of known conductance and adjust the Span pot (R17) for the corresponding mA value.4.Remove the sensor from solution and verify that the sensor reads 4.00 mA.5.Repeat steps 2 through 4 as necessary.mA =[(Known Cond./Full Scale Cond.) • 16 mA] + 4 mA NOTE:The current output can be monitored in several ways (see Figure 8)5Figure 4Display BoardInstallation Drawing part no. 3-8000.3902.3 Installing Optional Display BoardThe addition of the display board option (p/n 3-8000.390) to the conductivity transmitter is done in the following manner.1. Remove snap-on cover allowing access to the P4 connector.2. Plug the four conductor ribbon cable into the P4 connector, see Figure 4.3. If necessary use a small blade (e.g Exacto knife)to remove any conformal coating from the standoff holes or calibration pot access holes.4. Carefully snap the display board onto the three standoffs.5. Re-calibrate the instrument as explained in section 2.2.62.4 Display Board Range AdjustmentThe display board displays from zero to one hundred percent of range. This PCB has aone-point calibration which may need to be done at installation.1. Re-calibrate per section2.22. Calculate percentage of full scale and adjust Range pot on display board so that the display shows the proper percent of Full Scale.Model no.

However, when possible the transmitter should be located so as to minimize the effects of temperature gradients and to avoid vibration and shock.3.2 PositioningIn order to achieve good repeatable results care must be taken in the placement of the sensor. It is important that the sensor electrodes are fully immersed in the process fluid. Flow rates around the sensor must be limited so as not to produce air pockets which will affect the signal path through the fluid. We recommend that you do not mount completely upside-down as sediments may become trapped in the sensor and that you do not mount at the very top of the pipe because the pipe might not always be full.7The information provided on sensor positioning are recommendations only. The primary consideration is that the electrodes are in full contact with the process fluid.If sediments are present we recommend avoiding the 6O'clock position. Figure 6I n-line Sensor Positioning DiagramChapter 3Installation3.3 In-Line InstallationsThe 8800 Conductivity transmitter sensor system is designed for installation into a pipe using standard +GF + SIGNET fittings, (up to 4 inch) or the optional +GF + SIGNET pipe adaptor fitting (p/n P31515-0V200). Refer to section 3.4 for additional information.3.4 In-line Fitting Options These fittings provide the proper installation parameters that are critical to the calibration of the conductivity system.Fitting Installation/Plastic Fittings Tees:•All tee fittings sold by +GF + SIGNET are "glue-on" type except for the PVDF tees which are thermally fused. Be aware that PVC and CPVC tees require different types of primer and cement.•Tee fittings are available for pipes from 0.5 to 4 inches in diameter.Saddles:•Plastic "glue-on" saddles are available for lines from 2 to 4 inches in diameter.•2 to 4 inch "glue-on" saddles require a 1-7/16inch hole in the pipe. (O-ring not used with glue-on type)•The hole must be completely deburred to be free of any projections.•When assembling plastic saddles, the arrows on the wedges must match the direction of the arrows on the pipe saddle.Misc:+GF + SIGNET also offers a pipe adaptor specifically designed for installing +GF + SIGNET analytical sensors into in-line applications8Caution: Wheninstalling saddlefittings, depressur-ize and drain pipebefore drilling fitting hole.+GF + SIGNETplastic "glue-on" Tee Fitting+GF + SIGNET Plastic"glue-on" Saddle Fitting(p/n P31515-0V200). This pipe adaptor can be installed in any standard 1-1/4 inch FNPT pipe fitting.Fitting Installation/Metal FittingsWelded fittings MUST be installed by a certified welder.The plastic sensor insert in the Weldolet fitting MUST be removed during the welding process.When reinstalled, it is important that the insert be threaded to the proper height "H" dimension to ensure full insertion of the sensor electrodes,see page 10.• 2 to 4 inch Weldolet fittings require a 1-7/16inch hole in the pipe.•The hole must be completely deburred to be free of any projections before installing the Weldolet fitting.Pipe Tees: Metal Pipe Tees are available for 0.5to 2 inch metal pipes. Materials include iron,carbon steel, stainless steel, and copper or bronze. All tees are threaded with NPT threads except for copper and bronze tees, which have solder or braze type fittings.•Use thread sealant compound on fittings with threaded connections.9+GF + SIGNET "weld-on"Weldolet Fitting +GF + SIGNET Metal Pipe Tee Fitting+GF+ SIGNET Weldolet Fitting103.5 Submersible InstallationsThe 8800 Conductivity transmitter sensor system can be made submersible through the use of the submersible kit p/n 3-2700.391 and extension cable, p/n 3-8800.261-XX (-XX designates overall cable length from -01 to -12 ft., see Figure 1.3.6 Electrical InstallationThe transmitter has a 1/2 inch conduit opening for power/signal wiring, see Figure 7.The sensor input connection is located on the lower PCB (below optional Display PCB). To access the connector, remove the housing cover followed by the electronics cover (snap on/off).The connector is now accessible between theFigure 78800 ConductivityTransmitter In-lineInstallation11Signal wiring should not run in conduitor in open trays with HVAC wiring and should not be run near heavy electrical equipment. Leads should be color coded for polarity identification.The conduit connection on the transmitter housing should be sealed or plugged to avoid accumula-tion of moisture in the housing. If the conduit is not sealed, the transmitter should be mounted with the opening downward for draining.Signal wiring may be ungrounded or grounded at any place in the signal loop. Power supply regula-tion is not critical. Make sure that the power supply source conforms to the requirements of thetransmitter and that the current rating of the supply is not exceeded, particularly if more than one transmitter is connected to the supply in parallel.NOTE:This transmitter is designed to eliminate ground loops and other electrical interactions between system components even if several transmitters are powered by a common supply in parallel.Make sure that electrical characteristics of the remote output device are compatible with the transmitter output: Total load resistance must not exceed 700 ohms using a 24 VDC power supply. Total load resistance is the sum of the individual resistances of all devices which are connected in series with the signal output lead.Equation:RL = V S -10/0.02where R L = Load Resistance in ohms V S = Supply Voltage 10 = Minimum operating voltage0.02 = 20 mA (maximum current)1213Chapter 4Conductivity Sensor Maintenance 4.1 Maintenance TipsThe electrodes contact the solution and transfer a signal through the solution being measured. It is recommended that the electrodes maintain contact with fluid. If allowed to air dry, precipitates may form on the electrodes causing higher than normal readings and possibly contaminating the process fluid. If precipitates form, the electrodes may be cleaned by immersing the sensor in warm water and scrubbing the electrodes with a soft nylon brush.It is important that the sensor is not exposed to oils which may coat the electrodes. This may seriously affect the readings.In extreme cases it may be necessary to clean the sensor with alcohol to remove oils. Werecommend using a cotton swab and brushing the electrode clean instead of dipping the entire sensor body in acetone.In submersible applications the sensor should be located fully immersed and away from the presence of any bubbles.In some instances it may be necessary to devise a periodic maintenance schedule to clean the electrodes and verify calibration.4.2 Replacement Parts144.3 Troubleshooting Guide Problem Action Cause• Gain pot set too high • Incorrect operating range • Excessive Quiescent current •Application range exceeds the electronics range.•Unit is not properly calibrated•Range pot misadjusted• Check unit model number, see Unpacking and Inspection section (opposite page #1) • Re-calibrate, see page 4 • Re-calibrate display, see page 5•Application range belowthe electronics range • Sensor not connected Display/outputreads off scale •Check unit model number, see Unpacking and Inspection section (opposite page #1)•Check sensor connection Display/outputreads zero(4 mA)• System power or ground OPEN • Check system wiringDisplay is blank/no current • Reduce Gain/Span potadjust• Check unit model number, see Unpacking andInspection section (opposite page #1)• Send for repairTransmitter cannot be calibrated (insufficient Zero adjust)• Incorrect operating range • Unit not calibrated • Output transistor damaged • Check unit model number, see Unpacking andInspection section (opposite page #1)• Re-calibrate, see page 4• Send for repair• Air bubbles contacting sensor • Coated electrodes • Leaking submersion kit• Check installation• Clean sensor, see page 11• Clean/replace cableinstall new seal Transmitter output changes erratically Transmitter cannot be calibrated (insufficient Gain adjust)15Specifications Optional Display:0 - 100%, 2-1/2 digit LCD(factory installation recommended),#3-8020.390Loop power:10 to 30 VDCLoop impedance:•1Ω @ 10 VDC•100Ω @ 12 VDC•1000Ω @ 30 VDCElectronics operating temp:•-15 to 50 °C (5 to 122 °F)Max sensor pressure/temperature:•7 bar @ 20 °C (100 psi @ 68 °F)• 1.7 bar @ 90 °C (25 psi @ 194 °F)Operating ranges:•-1P0 to 20 µS0.05 cell•-2P0 to 200 µS0.05 cell•-3P0 to 2,000 µS 2.0 cell•-4P0 to 10,000 µS 2.0 cellCurrent output:2-wire, 4 to 20 mA signalAccuracy:±1% of rangeRelative Humidity:0 to 95%, non-condensingEnclosure materials:•Electronics enclosure:Glass-filled PP, NEMA 4X/IP65•Enclosure seal:Viton®•Window:PolycarbonateWetted sensor materials:•Sensor body:Glass-filled PP•Electrodes:Titanium•Sensor o-rings (2):Viton®•Optional o-rings:EPR, #1224-0021Kalrez, #1228-0021Immunity:EN50082-1Emissions:EN55011Agency Approvals:CE16Figure 98800 Conductivity TransmitterDimensional Views 2.0 Cell Constant -3 (0 to 2,000 µS)-4 (0 to 10,000 µS)0.05 Cell Constant -1 (0 to 20 µS) -2 (0 to 200 µS)17Warranty Limited Two-Year WarrantySignet Scientific Company warrants its instrumentsto be free from defects in material and workman-ship under normal use for a period of two yearsfrom the date of purchase by the initial owner, orthree years from date of manufacture, whichevercomes first, as described in the followingparagraphs.This warranty does not cover defects caused byabuse or electrical damage.

GF流量 电导 浊度安装条件及使用说明

GF流量 电导 浊度安装条件及使用说明

II. 安装角度由于重力作用会加大转轮与轮轴间的摩擦,所以转轮流量计的运行受安装角度影响。

管道中的气泡与沉淀物会影响测量精度,严重时会阻碍转轮运行。

I. 管路上的安装位置• 流量计在管路上的正确安装位置可以保证得到正确的流态。

为了得到充分的湍流状态,在流量计上游预留充分的直管段长度是非常重要的。

这样稳定的流动状态可以保证转轮流量计准确测量。

• 下图阐示了安装塑料或金属转轮流量计时,推荐的上下游最小直管段长度。

• 在任何情况下,请尽可能选择流量计上游是无扰动的直管段。

注:仅提供了管径为DN15~DN300(1/2~12”)的K系数。

对于其它管径,请联系技术支持。

转轮流量计的竖管安装:• 为了保证流体是满管状态,流量计要安装在由下至上流向的管段上,在任何情况下,都推荐这种安装。

• 竖管安装时,一般不推荐流向朝下的方式。

转轮流量计的水平管安装:• 为了避免气泡的影响,推荐流量计安装在垂直线左右45度的位置。

更大的安装角度会使转轮与本体间的摩擦加大,在测量范围低端会影响流量计的性能。

• 正上方安装会因为气泡聚集在管道顶侧而使流量计受到干扰。

• 倒置安装会因为沉淀物聚集而卡住转轮。

因此如果管道中有沉淀物,一定不能在管道底部安装。

K系数:K系数(单位体积对应的脉冲数)的作用是将流量计输出的频率信号折算成流量值。

Signet提供的所有流量计的K系数值对应的体积单位只有加仑(Gallon)与升(Liter)。

对不同的管径,不同的管材,以及不同种类的安装件,K系数都是不同的。

对于除了水以外的其它流体,K系数需要在现场进行设置。

流量计安装提示• 为了保证流量计插入到正确位置,请使用Signet专用安装件。

• 流量计上游直管段的推荐长度是用管道内径(I .D .)的倍数表示的。

要注意,根据流量计上游阻流设备的不同,这个倍数也是不同的。

• 转轮流量计可以用在类水的流体中,但要保证流体不含颗粒物(颗粒物直径<100微米)、不含铁屑、无污垢。

给程序选定出合适的温度补偿系数:1)输入0.00清除8850的温度补偿系数2)加热样本溶液至接近程序温度的最大值。

将传感器置于样本溶液中,等待几分钟至稳定。

进入察看菜单,将显示的温度和电导率值记录在下列空格中显示温度:T1 = ℃显示电导率:C1 = μS(不要将该步骤用于电导率为0.055μS 至0.1μS的溶液中,有一条内在的纯水曲线适用于该范围。

此范围应该使用出厂默认设置(2.00%/℃))3)冷却样本溶液至接近程序温度的最小值。

将传感器置于样本溶液中,等待几分钟至稳定。

进入察看菜单,将显示的温度和电导率值记录在下列空格中显示温度:T2 = ℃显示电导率:C2 = μS(推荐第二步和第三步间的电导率变化为10%)4)将第二步和第三步的记录读数代入下式中100×(C2 -C1 )TC=(C2×(T1-25)) – (C1×(T2-25))例:样本溶液测得电导率为205μS@48℃,冷却后测得电导率为150μS@23℃。

(C1 =205 ,T1 =48,C2 =150,T2 =23)TC计算如下:100×(205-150)TC= =1.42%/℃(150×(48-25)) – (205×(23-25))PPM系数当选择PPM显示单位时,该特征才适用。
