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 which isolates the strain gauge bridge from the process liquid or gas. The back of the sensor is usually vented to atmosphere to compensate for barometric pressure changes.

The 552 has a separate epoxy potted electronics module which plugs-in. The advantage is that the module can be replaced if in the event of failure. An integral indicating meter can be added to the housing.
