Model 592

SKU: 592

Pressure Transmitter, Cable Suspended, Remote Electronics

The Delta Controls Model 592 Pressure Transmitter features electronics that are separated from the sensor and mounted above ground for ease of testing, recalibration, and inspection. The sensor is mounted in a heavy 316 Stainless Steel 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 592 converts this pressure into a 4-20 mA dc level signal. The sensor is connected through a vent tube to atmospheric pressure for a reference.

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

The 592 is extremely 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 0.75 inch MPT hole.
