The Campbell Scientific Submersible Pressure/Temperature sensors, CS450 and CS455, are designed to provide a reliable, accurate pressure (level) and temperature measurement that is fully temperature compensated. The piezoresistive sensor is housed inside a 316L Stainless Steel (CS450) or Titanium (CS455) body and uses a vented cable.
With a 24-bit analog-digital converter built in, the sensor offers mains power frequency rejection and a 0.1% Full Scale accuracy over a 0 – 60 degrees range with measurements controlled by SDI-12 or RS-232 terminal commands. This operation allows the sensor to have a very low current consumption from an input voltage range of 6 – 18V DC.
The CS450/CS455 sensors are available in a number of range options:
