6542 Hydrostatic Water Depth & Temperature Probes

The model 6542 Hydrostatic Water Depth and Temperature Probes provide accurate long term measurements of water depths in standard ranges of 1, 2, 5, 10 and 20 meters, and water temperature from 0 to 60 °C. 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.

Two versions are available, an analog output version (0-2.55 VDC) and a digital output version (SDI-12 and HSIO signals). The analog output version has an accuracy of 0.3% full scale and the digital version has an accuracy of 0.2% full scale.

The 6542 uses the same digitally corrected pressure sensor type as the Model 8007WDP Digital Water Level Recorder. It is housed in a rugged stainless steel casing, with a Delrin nose-cone and is fully sealed and temperature compensated. The internal temperature transducer is the same type as the Model 6507A Red Thermistor Probe and is supplied with a 15k reference resistor.

An integral cable contains a vent tube for barometric compensation and a Kevlar support member for longitudinal stability. The cable's individual signal wires are epoxy sealed into the casing to protect against water ingress. Each transducer is shipped with a vent filter that prevents moisture from entering the cable vent tube. Specifications
