A measurement transducer having a sensor for converting a physical or chemical variable into an electrical signal which can be further processed, and an electronics unit proximate the sensor, for pre-processing the electrical signal and generating a measurement signal, wherein an evaluation device is connected to the receiver by an interface for transmitting the measurement signal and serves to determine a measurement value as a function of the measurement signal and output the measurement value, and so that the sensor can be operated at a relatively high temperature and the electronics unit arranged proximate the sensor, for reducing measurement noise is operable at a relatively low temperature, the electronics unit proximate the sensor, is provided with a thermal insulation with respect to the sensor and is cooled by a heat pipe, and where the evaluation device housing approximately at ambient temperature preferably serves as a heat sink. |
