ABSTRACT:
An adapter assembly for a pressure sensor. The adapter includes a sensor housing that has a first port and a second port that are both in fluid communication with an inner chamber of the housing. The assembly further includes a membrane housing that is pressed into the first port of the sensor housing and connected to a fluid line. Extending from the membrane housing is a membrane which separates the sensor housing inner chamber into a first subchamber and a second subchamber. The first subchamber is in fluid communication with the fluid line. The second subchamber is in fluid communication with a pressure transducer which is pressed into the second port of the sensor housing. Any variation of pressure within the fluid line will cause a change in the volume of the first subchamber. The change in the first subchamber volume will deflect the membrane and vary the volume of the second subchamber. In accordance with the ideal gas equation, the change of the second subchamber volume will vary the pressure of the second subchamber. The pressure transducer senses the change in the second subchamber pressure. The change in the second subchamber pressure corresponds to the variation in the line pressure. The membrane can be removed so that the pressure transducer can be reused even in contaminated environments.
