Abstract: Described is diagnosing radiometric detectors. The pulse amplitudes of the pulses acquired by the radiometric detector can be measured and stored temporarily. The pulse amplitude distribution determined in this manner is compared to a reference amplitude distribution, whereby error diagnosis and, if applicable, recalibration of the measuring device are made possible. In this manner temperature drifts and damage to the scintillator, EMC radiation and an increased rate of dark pulses of the photosensitive component may be detected and corrected.

Abstract: A two-wire sensor (6) is attached to one pole of a voltage distribution source (U) by an initial connecting line (V1) in which a current-limiting resistor (R1) is positioned and is attached to the other pole by a second connecting line (V2). Parallel to the series connection consisting of the two-wire sensor (S) and the current-limiting resistor (R1) is at least one limiting diode (D1). A current regulator (SR) which is attached to the poles of the power source (U) regulates a parallel current (I) which runs parallel to the current through the two-wire sensor (D), so that there is a sum current at the poles of the power source (U) that always corresponds to the measured value delivered by the two-wire sensor (S). The regulating inputs of the current regulator (SR) are connected to the terminals of a current-sensing resistor (R2) positioned in a connecting line (V1). When a HART®-interface is used with the two-wire sensor (S) a HART®-resistor (RH) is positioned in one of the two connecting lines (V1).
