Model 572

SKU: 572

Pressure Transmitter, Modular Electronics, Sanitary Service

The Delta Controls Model 572 Level and Pressure Transmitter was designed specifically for food, pharmaceutical and ultraclean applications. The 572 consists of a potted electronic module in a housing which is mounted with a modular pressure sensor as a packaged assembly. The wetted sensor is constructed of 316 S.S. The body is polished and free from crevices, cracks, and voids that can harbor contaminants. The back of the sensor is usually vented to atmosphere to compensate for barometric pressure changes.

Cleaning of the Delta Controls Model 572 can easily be accomplished by disassembly and manual washing, or it can be cleaned and sterilized in place. The Model 572 can also be used as a liquid level transmitter in vented tanks. The pressure at the bottom of a vented tank containing liquid is linearly proportional to the height and density of the liquid. Use the TPC Corrector to compensate for the gas space pressure when the tank is pressurized.
