Abstract

A device (1) for determining a measured variable, that allows an as simple as possible adaptation to the measurement conditions, is achieved in that the device (1) has a sensor unit (2) and a transmitter (3). The sensor unit (2) generates an electric primary signal in dependence on the measured variable, and communicates the primary signal via an analog output interface (4) to the transmitter (3) which processes the primary signal. Furthermore, the sensor unit (2) and transmitter (3) are advantageous by themselves, and the sensor unit (2) preferably allows for offline calibration under constant surrounding conditions.
