Measuring transducer for process instrumentation, has sensor for detecting physical or chemical dimension and for generating measuring signal, where sensor has sensor element, which is arranged on substrate

摘要

The measuring transducer has a sensor (1) for detecting a physical or chemical dimension and for generating a measuring signal. A control- and evaluation unit is provided to determine and output a measured value of the physical or chemical dimension in dependence of the measuring signal. The sensor has a sensor element, which is arranged on a substrate (2). An electric line (3) for monitoring the substrate for signs of cracking or breakage is arranged on the substrate in the area of the sensor element. An independent claim is included for a method for monitoring the condition of a sensor for detecting a physical or chemical dimension and for generating a measuring signal in a measuring transducer for process instrumentation.
