ABSTRACT:
A sensor unit for measuring a measurement variable in a medium, in particular in an aggressive liquid or gaseous medium, comprises a sensor that is arranged in a sensor capsule and has a sensor region that is arranged on a base body. In order to detect the measurement variable in the sensor region, a measurement opening is provided in the sensor capsule. On a side facing the measurement opening, the sensor region has a measurement surface that is provided with measurement electronics. An electrical supply line is provided on the sensor for the purpose of transmitting a sensor signal that is generated by the measurement electronics. A plated-through hole is provided in the base body. The plated-through hole is used to connect the measurement electronics to the electrical supply line via signals through the base body, on a base side of the sensor that faces away from the measurement opening.
