SKU: 566

Pressure Transmitter, Large Diaphragm, Remote Electronics

The large diaphragm Delta Controls Model 566 Pressure Transmitter features an electronics housing mounted above ground for easy testing, recalibration, and inspection. When installed in a lift station, sump, basin, or other containment, the strain gauge sensor detects the liquid level as a function of the height and density of the liquid above it. 566’s electronics and calibration adjustments are contained inside the remote enclosure the with strain gauge sensor separate in the sensor body. It is of remote construction and is field repairable.

The open diaphragm cannot become plugged or rendered inoperable by liquids with high solids content such as sewage, wastewater, and slurries. The diaphragm is fabricated from tough EPDM rubber, and is coupled to the strain gauge through a nontoxic fill. The face has superior resistance to damage from gravel, and other moving solids. 566’s large three inch active face size, and its smooth outer surface makes it extremely durable and reliable in harsh services. A vent tube connected directly to the sensor compensates for atmospheric pressure changes. The optional desiccant filter, or isolation bladder, prevents condensation in the vent tube. No refilling or maintenance is required for the bladder.
