Model 572 • Pressure Transmitter, Modular Electronics, Sanitary Service Features Two-wire loop powered 4-20 mA signal Fits Tri Clamp, APC, and other sanitary connections Ultraclean water service applications CIP/SIP service applications Removable electronic module Polished body Zero and span pots for field recalibration Surge protection Optional LCD display Maintenance free operation Model 572 Description The Delta Controls Model 572 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 Stainless Steel. 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. Easily clean Model 572 by disassembling and manually washing, or clean and sterilized in place. The 572 is 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.
