Abstract

In a method for compatibility checking of a measuring system including a measurement transmitter and a sensor, a first signature is externally created for an identifying data set and is stored in the measurement transmitter. After transmission of the identifying data set from the measurement transmitter to the sensor, a second signature is calculated for the identifying data set in the sensor. If the signatures match, then the measurement transmitter and the sensor are compatible and the measurement transmitter can access data and/or functions of the sensor.
