Abstract:
1. A method for operating a sensor in a multisensor system, especially in a field device in the form of a measuring device for process automation technology, comprising the steps of: evaluating data output from the sensor by the measuring device connected with the sensor; supplying energy with the measuring device to the sensor; before start-up of the sensor, it is checked whether, with start-up of the sensor, a maximum consumption of electrical energy of the measuring device would be exceeded; ascertaining, before start-up of the sensor, the energy consumption of all electrical assemblies operated in the measuring device; and comparing the energy consumption ascertained, including the energy consumption for the sensor to be placed in operation, with the maximal energy consumption of the measuring device, wherein: in the case of a subceeding or equaling of the maximal energy consumption, the sensor is placed in operation; and a cleaning phase of the sensor occurs after start-up of the sensor.
