Abstract
A measurement transducer, comprising: a sensor module having a sensor element, sensor electronics and a main electronics module. The sensor element emits sensor signals, and the sensor electronics processes the digitized sensor signals with a transmission function and provides processed sensor measurement values on a digital interface. The main electronics module is functionally connected to the sensor electronics and a logic unit, and a communications interface. The logic unit is configured to receive the sensor measurement values provided on the digital interface and to cause the output of a measurement signal corresponding to the sensor measurement values through the communications interface. The logic unit is configured to carry out a monitoring function. The monitoring comprises, in addition to a currently provided sensor measurement value, the reception of the associated digitized sensor signals, with the aid of a test function which comprises the transmission function. The logic unit is also configured to provide the control measurement value to the sensor electronics, wherein the sensor electronics is configured to carry out a comparison between the control measurement value and the sensor measurement value and to cause the communications interface, via an alarm output, to directly emit an error signal in the event of deviations.
