CAUTION
SENSOR/PROCESS APPLICATION COMPATIBILITY
The wetted sensor materials may not be compatible with process com position and operating conditions.
Application compat ibility is entirely the responsibility of the user.
WARNING
Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process
temperature is lowered to a safe level!

Specifications 403 and 403VP
Wetted Materials titanium, PCTFE, 316 SS, EP
Temperature Range
Maximum Pressure 250 psig (1825 kPa abs)
NOTE
Elastomers and uorocarbon resins are compatible with 21CFR177. Elastomers also meet the requirements of USP
Class VI. Stainless steel contains <5 % delta ferrite. All surfaces in have 16 microinch (0.4 micrometer) Ra nish.
32–221 °F (0–105 °C) Sensors tolerate
steam sterilization to 135 °C
Installation
Depending on the option selected, the sensor can be installed in either a 1 ½-inch or 2-inch Tri-Clamp tee. The gasket,

°
clamp, and tee must be supplied by the user. The electrodes must be completely submerged in the process liquid, i.e., up
to the inside surface of the ange.
If the sensor is installed in a side stream with the sample draining to open atmosphere, bubbles may accumulate on the
electrodes. Trapped bubbles will cause errors. Normally, as bubbles accumulate the conductivity reading drifts down. To
control bubble formation, apply a small amount of back pressure to the sensor.

Wiring through a Junction Box
If wiring connections are made through a remote junction box (PN 23550-00), wire point-to-point. Use cable
23747-00 (factory-terminated) or 9200275 (no terminations).

sensor, looking down)
Cleaning the Sensor
Use a warm detergent solution and a soft brush or pipe cleaner to remove oil and scale. Isopropyl alcohol (rubbing
alcohol) can also be used to remove oily lms. Avoid using strong mineral acids to clean conductivity sensors.
Calibration
PURSense conductivity sensors are calibrated at the factory and do not need calibration when rst placed in service.
Simply enter the cell constant printed on the label into the analyzer.
After a period of service, the sensor may require calibration. The sensor can be calibrated against a solution having
known conductivity or against a referee meter and sensor. If using a standard solution, choose one having conductivity
in the recommended operating for the sensor cell constant. Refer to the analyzer manual or product data sheet
for recommended ranges. Do not use standard solutions having conductivity less than about 100 uS/cm. They are
susceptible to contamination by atmospheric carbon dioxide, which can alter the conductivity by a variable amount as
great as 1.2 uS/cm (at 25°C). Because 0.01/cm sensors must be calibrated in low conductivity solutions, they are best
calibrated against a referee meter and sensor in a closed system.
For more information about calibrating contacting conductivity sensors, refer to application sheet ADS 43-024, available
on the Rosemount Analytical website.

Troubleshooting
PROBLEM PROBABLE CAUSE SOLUTION
Wiring is wrong. Verify wiring.
RTD is open or shorted. Check RTD for open or short circuits.
See Figure 11.
Off-scale reading
Noisy reading
Reading seems wrong (lower or
higher than expected)
Sluggish response
Sensor is not in process stream. Be sure sensor is completely submerged in
process stream.
Variopol cable is not properly seated. Loosen connector and reseat.
Sensor has failed. Perform isolation checks. See Figure 12.
