Abstract: A method for measurement of the casting level in a mould incudes the steps of: a) impressing a temporal current profile into a transmitting coil that is arranged at the mould, during a measuring time interval; b) measuring a temporal signal profile resulting in a receiving coil during the measuring time interval, wherein the receiving coil is coupled inductively to the transmitting coil; c) selecting a time window within the measuring time interval, and d) evaluating the measured temporal signal profile within the selected time window to determine the casting level.

Abstract: An apparatus for measuring ionizing radiation includes a detector having a cathode, an anode, a counting gas between the cathode and the anode for generating gas ionization by ionizing radiation, a voltage source for applying a voltage between the cathode and the anode, and a current measuring device for measuring a detector current between the cathode and the anode. The detector current is generated in the counting gas by the ionizing radiation. The apparatus further includes a setting device, wherein the setting device is configured for independently setting the apparatus into different operating modes depending on the measured detector current, and/or wherein the setting device is configured for independently setting the apparatus into different measurement ranges depending on the measured detector current.

Abstract: A device for monitoring an automatic drift compensation of a scintillation counter may include a drift compensation monitoring unit which is designed to evaluate a counting rate caused by a monitoring radiation source for the purpose of monitoring the automatic drift compensation.

Abstract: In a circuit for safe forwarding of a physical or technical variable between at least two systems in communication with one another, which variable is represented by the value of a loop current (Is), which is adjusted by a control unit (11) by means of a current output circuit (13) in a current loop (20, 60), the current output circuit (13) has at least two parallel-connected final control elements (131, 132), controllable by the control circuit (11), as current sources for mutually independent adjustment of a value of the loop current (Is). The final control elements (131, 132) are in series with at least two likewise series-connected measurement resistors (133a, 133b).
