Description

The Delta Controls Model 565 Level Transmitter is a completely self-contained head pressure type level transmitter. The electronics and calibration adjustments are contained inside the body with the strain gage sensor. It is of modular construction and is field repairable. The cable is sealed to the transmitter body.

When installed in a lift station, sump, basin, or other containment, the strain gage sensor detects the liquid level as a function of the height and density of the liquid above it. Because the diaphragm is completely open to the product being measured, it cannot be plugged and rendered inoperable by liquids with high solids content such as sewage, wastewater, and slurries. The diaphragm is fabricated from tough rubber and is coupled to the strain gage through a nontoxic oil fill. The abrasion resistant face has superior resistance to damage from gravel and other moving solids. Its large 3" 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 automatically compensates for changes in atmospheric pressure. A desiccant filter or isolation bladder prevents condensation in the vent tube. No refilling or maintenance is required for the bladder.
