Abstract
A sensor apparatus includes pressure and temperature sensors for measuring the pressure and temperature of high-pressure fluid media within a vessel. The pressure sensor is disposed in a sensor cavity that is coupled to a measurement port, and the leads of a temperature sensor that is disposed in the measurement port pass through the body of the sensor apparatus to a termination cavity that is physically isolated from the sensor cavity.
Claims4
A sensor apparatus for sensing a pressure and temperature of a fluid media within a vessel, comprising:
- a molded plastic housing including a measurement port that is inserted into said fluid media through a wall of said vessel, a sensor cavity coupled to said measurement port by a media conducting passage, and a termination cavity that is physically isolated from said sensor cavity;
- a pressure sensor mounted in said sensor cavity in sealing relation with respect to said media conducting passage to measure the pressure of said fluid media;
- a temperature sensor including a sensing element in contact with the fluid media within said measurement port to measure the temperature of said fluid media, and one or more electrical leads with end portions that extend into said termination cavity without passing through said sensor cavity;
- and
- a set of electrical terminals molded into said housing for electrical connection to said pressure and temperature sensors, including one or more electrical terminals having end portions that extend into said termination cavity for attachment to the end portions of said electrical leads.
