A circuit arrangement for feeding a resistance-type sensor into a multiposition measuring device is described in which each resistance-type sensor (R) is supplied with a constant direct voltage (UA) from a feed circuit (A). Independently of the circuit connected to each resistance-type sensor, only four switches (S1 to S4) are required for each measuring point, two switches being provided for supplying the feed circuit with a constant direct current (IK) and two switches being provided for transmitting the measurement value to a measuring device (V3). Current source (K) and measuring device are located in a central measurement value detection system (Z) which initiates the selection of the individual measuring points via the switches (Figure 1). <IMAGE>
