The instruments use the hydrostatic pressure of water to measure water depths in various environments. The instruments are used for measuring water level and are ideal for monitoring drainage levels, bore depth and river height.
Probes provide accurate long term measurements of water depths of 1m to 100m in standard ranges, with an accuracy of 0.2% full scale. The sensor is fully sealed and temperature compensated. A hermetically sealed case with a protection type IP 68 allows the pressure sensor to be immersed down to a depth of 100m. The inner vented connection cable makes pressure compensation of the measuring cell against the atmosphere possible and thus hydrostatic pressure measurement. The pressure sensor special for submersible measurement meets the electromagnetic compatibility (EMC) requirements. The mechanical fastening of the pressure sensor does not require any additional strain relief, as the construction of the cable is suitable to take a maximum tensile force of 1000 N. The cable’s individual signal wires are epoxy sealed into the casing to protect against water ingress. This probe is ideal for monitoring drainage, bore depth and river height. It can also be used to measure water with dissolved solids and other liquids.
