Description
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, it’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.
