Abstract (en)
[origin: EP0927982A1] The supply has a transformer for voltage isolation between the transducer and the d.c. source. The transformer primary winding is connected to the source via a chopper. The secondary is connected to a rectifier (31) that supplies a rectified chopped current to the transducer at a defined level. For connecting an active transducer (41), which outputs a d.c. current corresp. to a measurement value, an adapter circuit (60) controlled by the transducer output current is connected between the outputs of the rectifier circuit and the supply connections provided for the connection of the active transducer. The adapter circuit loads the rectifier with a d.c. current proportional to the transducer output current.
