Combined pressure and temperature transducer

A combination pressure and temperature transducer particularly adapted for use with high temperature fluid comprising:

• an elongated tubular probe member having first and second open ends and sealing structure disposed therebetween so that the first end of the tubular probe member can be sealingly inserted though an opening in a wall into a location to be monitored, a radial, outwardly extending flange mounted on the second end of the tubular probe member, a sensing element including a pressure responsive diaphragm with strain gauges mounted thereon, the sensing element received at and closing the first open end, a first heat resistant printed circuit board (PCB) mounted in the tubular probe member adjacent to the sensing element, the first PCB having wire bond pads and contact pads, wires bonded to the strain gauges and to the wire bond pads forming an electrical connection therebetween,
• an elongated inner connector formed of electrically insulative material received in the tubular probe member, the inner connector having an upper end extending out of the second end of the tubular probe member,
• a second printed circuit board (PCB) mounted on the inner connector at the upper end thereof, the second PCB having electrical circuit paths and contact pads and including electronic signal conditioning and amplifying components,
• the inner connector including a plurality of elongated, axial stress absorbing contact members having first and second opposite ends, the first end of each contact member in electrical engagement with a respective contact pad of the first PCB and the second end of a respective contact member in electrical engagement with the electrical circuit paths of the second PCB, and
• an outer connector and housing for attachment to the flange for providing an electrical interface with the transducer and for housing the second PCB whereby the sensing element and first PCB at the first end of the tubular probe member can be sealingly inserted through an opening in a wall into a flow of fluid at elevated temperatures with the second PCB physically separated from the first end of the tubular probe member outside the monitored location.
