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.
Key Advantages
Ideal for long-term deployment in harsh conditions
Technical 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.
