Abstract
An oil-fill pressure transducer including a flexible member configured to protect an isolation diaphragm and sensing element. The pressure transducer includes a sensing element mounted to the header, an isolation diaphragm mounted on the front side of the header, and adjacent to the sensing element such that an oil-fill cavity is defined between the sensing element and the isolation diaphragm. The flexible member is disposed adjacent to the isolation diaphragm and a retention member is disposed adjacent to the flexible member. A cavity in communication with the retention member is configured to transmit pressure media to the isolation diaphragm via the flexible member. The flexible member can include thru-holes. The flexible member may compress under an applied positive pressure change. The flexible member may temporarily separate from at least a portion of the isolation diaphragm under an applied negative pressure change.
