Model 552

SKU: 552

Pressure Transmitter, Modular Electronics

The Delta Controls Model 552 Pressure Transmitter Sensor includes an oil-filled 316-L Stainless Steel or Hastelloy® C-276 diaphragm to isolate the strain gauge bridge from the process liquid or gas. Model 552 can be field calibrated.

Model 552 features a robust potted electronics module. To compensate for barometric pressure changes, the back of the sensor is vented to atmosphere.
