ABSTRACT:
An electrical transducer has a sensor outputting a value corresponding to the quantity to be measured, an analog end stage connected downstream of the sensor, a processor circuit, and an analog measurement signal transmission path. The end stage converts the sensor output signal into an impressed output current related to the magnitude of the quantity measured, the electronic transducer being controlled with the processor circuit. The electrical transducer can be scaled by the user, has low inherent power consumption and ensures high response speed because the processor circuit in normal operation is shifted temporarily into a sleep mode, in the analog measurement signal transmission path an analog scaling unit is inserted, the output signal of the sensor and at least one analog setting value are supplied to the analog scaling unit, and the output signal of the analog scaling unit is supplied to the analog end stage.
