Abstract: The disclosed technology is a pressure transducer with a bleed valve built into the body of the transducer for purging liquid systems. The transducer assembly includes a body, a bleed valve port defined in the body and configured to accept a bleed valve, an interface port attached to the body, an adapter attached to a portion of the interface port, a header attached to the adapter and the body, a pressure transducer mounted to the header, and an internal cavity in communication with the interface port, the pressure transducer, and the bleed valve port. The bleed valve port is configured to vent a gas from the internal cavity. A bleed valve disposed in the bleed valve port is configured to controllably vent a gas from the internal cavity.

Abstract: A pressure restrictor for use with a pressure sensing element comprising a cylindrical member of a given diameter and length having a plurality of apertures directed from a first end to a second end is disclosed. A pressure restrictor housing holds and positions the cylindrical member in close proximity to the pressure sensing element at the second end by clamping the pressure restrictor between the housing and element. The apertures provided in the pressure restrictor are the sole path for application of pressure to the sensing element. The sensing element is a double diaphragm silicon sensor where one diaphragm is exposed to pressure and the other diaphragm is not exposed to pressure. Each diaphragm has located thereon a half-bridge wherein both half bridges are connected to provide a full bridge. The full bridge provides an output strictly proportional to pressure.
