Abstract
A pressure transducer assembly includes a transducer member supporting a transducer element for measuring pressure within an environment. The transducer member has a sealing surface surrounding the transducer element. A housing having an integral resilient member resiliently supports the transducer member and exerts a sealing force on the transducer member against a mating member secured to the housing.
Claims27
A transducer assembly comprising:
- a transducer member supporting a transducer element for measuring properties of an environment, the transducer member having a sealing surface surrounding the transducer element;
- a housing having an integral resilient member for resiliently supporting the transducer member and for exerting a sealing force on the transducer member against a mating member secured To the housing, the mating, member comprising a fitting having a cavity therethrough for sealing against the sealing surface of the traducer member and for surrounding the transducer element, the resilient member comprising a resilient rear wall of the housing, the housing having an interior with an opening thereto, the housing also having a protrusion extending from the resilient rear wall towards the opening of the housing and into contact with the transducer member;
- and
- a locking arrangement on the housing for locking the fitting to the housing, the fitting facilitating coupling of the transducer assembly to said environment.
