Model 563

SKU: 563

Pressure Transmitter, Modular Electronics, Extended Face

The Delta Controls Model 563 Pressure Transmitter consists of a potted electronic module and a flush diaphragm pressure sensor packaged in a one piece unit. The sensor is equipped with 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 diaphragm is vented to atmosphere to compensate for barometric pressure changes. A desiccant filter or isolation bladder prevents moisture buildup in the vent tube.

The 563 mounts on the side of and at the bottom of a tank or other containment and measures the pressure exerted on the sensor face by the liquid head. The pressure at the bottom of a vented tank containing fluid is linearly proportional to the height and density of the fluid. The flush diaphragm is intended for measurement of dirty or high solids content products that might easily plug the small openings and tubing connections of typical transmitters. The extended diaphragm configuration is typically used to gain access to the inside of a tank to avoid being plugged by deposits and sediment. The extended face allows the sensor to be located inside the vessel to insure that solids either fall off or do not become rigid enough to cause measurement errors. The 563 is useful for pressure measurement of pipelines handling liquids with entrained solids. The sensor does not have recessed cavities and therefore will not collect particles or plug up
