Page 9: Section 2: Installing The Sensor
Conductivity Sensors with 0.1 and 1.0/cm cell constants can be installed in ¾-inch pipe tees. Rosemount 400/400VP Contacting Conductivity Sensors can be installed in 1-inch tees with a ¾-inch bushing. If the sensor is installed in a pipe tee or flow cell with the sample draining to open atmosphere, bubbles may accumulate on the electrodes. - Page 10 Installation Instruction Manual May 2017 LIQ-MAN-400 Figure 2-7 Rosemount 400 with integral cable connection dimensional drawing Sensor c onfiguration Millimeter Inches Inches mm Inches Inch 0.01/cm 1.59 40.39 1.98 50.34 4.52 114.8 0.1/cm 0.687 17.45 1.11 28.15 3.65 92.71 1.0/cm 0.667...

Section 3: Calibration and maintenance Calibrating the sensor Rosemount 400/400VP Contacting Conductivity Sensors are calibrated at the factory and do not need calibration when first placed in service. Simply enter the cell constant printed on the label into the transmitter. After a period of service, the sensor may require calibration. For more... - Page 16 Calibration and Maintenance Instruction Manual May 2017 LIQ-MAN-400 3.1.2 Calibrating using a reference meter and sensor Connect the process sensors and reference sensor in series and allow the process liquid to flow through all sensors. Calibrate the process sensor by adjusting the process transmitter reading to match the conductivity measured by the reference meter.
- Page 17 Instruction Manual Calibration and Maintenance LIQ-MAN-400 May 2017 Orient the sensors so that air bubbles always have an easy escape path and cannot get trapped between the electrodes. Turn off automatic temperature compensation in the transmitter. Almost all process conductivity transmitter feature automatic temperature compensation in which the transmitter applies one of several temperature correction algorithms to convert the measured conductivity to the value at a reference temperature, typically 25 °C.

Page 18: Cleaning The Sensor
Calibration and Maintenance Instruction Manual May 2017 LIQ-MAN-400 Grab sample calibration should be used only when the conductivity is fairly high. a. The temperature compensation algorithm will most likely be linear slope. b. Confirm that both instruments are using the same temperature coefficient in the linear slope calculation. -

Instruction Manual Troubleshooting LIQ-MAN-400 May 2017 Section 4: Troubleshooting Troubleshooting Problem Probable Cause Solution Wiring is wrong. Verify wiring. Temperature element is open or shorted. Check temperature element for open or short circuits. Figure 4-1 Sensor is not in process stream. Be sure sensor is completely submerged in process Off-Scale Reading stream. - Page 20 Troubleshooting Instruction Manual May 2017 LIQ-MAN-400 4.1.1 Checking the temperature element Disconnect leads and measure resistance shown.
