Pressure Transmitter, Cable Suspended, Remote Electronics
The Delta Controls Model 592 Pressure Transmitter features an electronics housing mounted above ground for easy testing, recalibration, and inspection. Both are potted for maximum reliability. The sensor is mounted in a 316 Stainless Steel body. A rugged electrical cable interconnects the housing and sensor, and supports the body. The sensor measures the pressure of the liquid above it. The detected pressure, linearly proportional to the height of water above, converts it to a 4-20 mA signal equivalent to the liquid’s level. 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 may be checked or changed without the unit being installed in a well or pit.
The 592 is useful for measuring levels in tanks. The flexible cable is easy to install, even with minimal head room. The small body diameter allows it to be installed through a 0.75 inch NPT hole.
