Model 592

SKU: 592

Pressure Transmitter, Cable Suspended, Remote Electronics

The Delta Controls Model 592 electronics unit is separated from the sensor and mounted above ground for ease of testing, recalibration, and inspection. The sensor is mounted in a heavy 316 S.S. body. A rugged electrical cable interconnects them and supports the body. Both are potted for maximum reliability. The sensor measures the pressure of the liquid above it. This pressure is linearly proportional to the height and density of the liquid above it. The Model 592 converts this pressure into a 4-20 mADC level signal. The sensor is connected through a vent tube to atmospheric pressure for a reference.

Unlike capacitance and admittance type devices, the Model 592 is unaffected by algae and sludge coating. Also, itÂ’s calibration can be checked or changed without the unit being installed in a well or pit.

The Delta Controls Model 592 is also very useful for measuring levels in tanks. The flexible cable is easy to install, even when head room above a tank is minimal. The small body diameter allows it to be installed through a 3/4″ MPT hole. Use the TPC corrector to compensate for gas space pressure option when the tank is pressurized.
