Improvement of two-conductor thermoresistive converters with commutative inverting of sample currents
The improved method of compensation the influence of the lead wire resistance for two-wire resistance temperature detectors (RTDs) on the basis of commutation inverting of the reference measuring currents is proposed. For the averaging of signals generated as a result of commutation inverting of reference measuring currents, predominantly low-pass filters are used. Their usage limits the speed of temperature measurement.
