Abstract
A sensor plug for pressure and temperature measurement of a fluid medium includes a sensor body having a sensor body axis, as well as a pressure sensor disposed substantially concentrically on the sensor body axis. Also provided in the sensor body is a through orifice for connecting the pressure sensor to the fluid medium, and a temperature sensing element orifice having a temperature sensing element received therein. The temperature sensing element orifice has a temperature sensing element orifice axis that is inclined with respect to the sensor body axis in such a way that at its end pointing toward the fluid medium, it is inclined toward the sensor body axis.

24. A method for manufacturing a sensor plug for pressure and temperature measurements of a fluid medium, the sensor plug having:
- a sensor body having a sensor body axis, a through orifice and a temperature-sensing-element orifice disposed in the sensor body;
a pressure sensor disposed substantially concentrically on the sensor body axis, wherein the through orifice disposed in the sensor body is configured to connect the pressure sensor to the fluid medium; and
a temperature sensing element received within the temperature-sensing-element orifice;
wherein the temperature-sensing-element orifice has a temperature-sensing-element-orifice axis inclined with respect to the sensor body axis in such a way that an end of the temperature-sensing-element-orifice axis pointing toward the fluid medium is inclined toward the sensor body axis, wherein the sensor body includes a) an externally located threaded piece having an external thread and b) an insert having the through orifice and the temperature-sensing-element orifice, the method comprising;manufacturing the insert of the sensor body using the powder-metallurgy process; manufacturing the externally located threaded piece of the sensor body; fitting the insert into the threaded piece; and joining the insert and threaded piece in a positively-engaged, pressure-tight connection using a laser welding process.
- a sensor body having a sensor body axis, a through orifice and a temperature-sensing-element orifice disposed in the sensor body;
