Overview
The CS431 is a pressure transducer manufactured for use with Campbell Scientific data loggers. It measures both water level and water temperature in canals, wells, ponds, harbors, lakes, streams and tanks. Campbell Scientific data loggers measure the sensor's output and then converts the measured value to the desired units.

- Compatible with most Campbell Scientific data loggers
- Enhanced temperature calibration available (see Ordering Info)
- Stainless-steel body and Viton and Teflon wire seals resist corrosion
- Double-sealed cable harness protects the cable jacket and reduces the possibility of leakage
- End cone is interchangeable with an NPT inlet allowing easy hookup and field calibration
The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description
The CS431 uses piezoresistive strain gage technology to measure water level and an on-board thermistor to measure temperature. Piezoresistive transducers include a strain gage bonded to a pressure-sensitive diaphragm. Electrical resistance changes as pressure changes on the diaphragm.
The CS431 has a 316 stainless steel body and Viton® and Teflon® wire seals that resist corrosion. Its double-sealed, cable harness protects the cable jacket and reduces the possibility of leakage. The end cone is interchangeable with a ¼” NPT inlet allowing easy hookup and field calibration. You can choose a polyurethane or Teflon cable (see Ordering Info). Both cable options are vented.

Additional Compatibility Information
Data Logger Considerations
The pressure measurement requires two differential channels and one excitation channel, and the temperature measurement requires one single-ended channel and one excitation channel. The CR500 and CR510 do not have sufficient channels to measure both pressure and temperature.
