Pro-Range PR-PT604-H Submersible Water Level Sensor (20m Range, 4-20mA Output, IP68, 3M Cable)

This is a two-wire 4-20mA loop-powered sensor. Connect the red wire to your positive DC power supply (12-30V) and the black wire to your data acquisition input or PLC analog input module. The same two wires carry both power and the proportional current signal. Ensure your receiver is configured for a current loop input.

Yes, the stainless steel housing and PE cable are compatible with many non-corrosive, non-clogging liquids such as fuels, oils, and certain chemicals. However, for aggressive media, verify chemical compatibility with the housing and cable material. The sensor measures hydrostatic pressure, so the density of the liquid will affect the level reading and may require calibration scaling.

For submersible level measurement, lower the sensor into the tank or well until the sensing port is at the desired zero-reference depth. The sensor can be suspended by its cable or mounted via a threaded fitting (check datasheet for specific thread size). Ensure the cable gland is properly sealed. The sensor must be fully submerged for accurate measurement, and the vent hole in the cable must remain above the liquid level and be exposed to atmospheric pressure.

The sensor typically achieves ±0.5% Full Scale accuracy under standard conditions. The 1% FS rating is a more conservative, guaranteed specification. Accuracy can be influenced by temperature, installation, and media properties. For critical applications, refer to the detailed datasheet for temperature coefficients and non-linearity specifications to calculate total measurement uncertainty.
