Abstract
A device for measuring at least one physical quantity includes a direct voltage source and a measuring sensor coupled to the voltage source, which sensor is configured to measure a physical quantity. A current regulator is connected between the direct voltage source and the measuring sensor, and a voltmeter is connected in parallel with the measuring sensor so that a voltage detected by the voltmeter is indicative of the measured quantity.

A method comprising:
- providing a sensor configured to sense a physical condition,
- connecting a direct voltage source to the sensor,
- connecting a current regulator between the direct voltage source and the sensor, and
- connecting a voltmeter in parallel with the sensor to determine a voltage indicative of the physical condition sensed by the sensor.
