Abstract
A method and apparatus for checking a sensor which generates an electrical measuring signal on the basis of a non-electrical physical value. A test value transmitter is used to generate a non-electrical physical value (which is the same type as the physical value to be measured by the sensor) when an electrical checking signal is applied. The electrical checking signal and the electrical test signal are compared with each other and thus simulate a measuring operation of the sensor. The sensor is effectively checked, on the basis of its own physical measuring operation over the sensors entire measuring range.
