Model 566 • Pressure Transmitter, Large Diaphragm, Remote Electronics Features Large, rugged EPDM rubber diaphragm isolator for wastewater and slurries Supported by rigid pipe or cable 4-20 mA dc, 2-wire 316 Stainless Steel or Hastelloy® C-276 body PVC or TEF cable jacket Zero and Span pots for field recalibration Calibrate, test from electronic module Top side housing holds electronics Field repairable, modular design Model 566 Description The Delta Controls Model 566 Pressure Transmitter is a completely self-contained head pressure type level transmitter. 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 body with the strain gauge sensor, and the cable is sealed to the transmitter body. It is of modular 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.
