To simplify calibration and to simplify and broaden the operating functions, it is provided that the light source unit (1) is provided with a receiver device (9), which communicates with a control and evaluation device (6) in the light source unit (1), and the detector unit (2) is provided with a transmitter device (10), which communicates with the control and evaluation device (11) in the detector unit (2), so that a direct data exchange between the detector unit (2) and the light source unit (1) is made possible. In this way, it is for instance possible for the control and evaluation units, with the aid of controllable optical guide elements, to achieve an automatic optimization of the beam to the detector.

A control unit (6) is prepared such as to actuate the ejection mechanism (10) at predetermined time intervals or at predetermined distances in space. A portable transmitter/receiver device (8) is designed to detect at least one of the transponders (7) dropped off and to generate a signal representative of the direction in which that transponder (7) is located. A portable display device (4) receives the direction signal of the transmitter/receiver means (8) and offers the wearer a visual and/or acoustic display of the direction.

摘要： A device for measuring the concentrations of paramagnetic gases in a gas sample has at least one modulatable magnetic flux source, which has an air gap, to which a gas sample can be fed. A controllable power source, for generating current and voltage signals, is coupled with the modulatable magnetic flux source in order to generate a modulatable magnetic flux within the air gap. Two measuring points are arranged at least partly within the air gap. Each measuring point has an electrically controllable heating device and a heat conduction-measuring unit or resistive measuring device. Each measuring point is coupled with a variable power source to heat the heating device to a working temperature. Each measuring point is coupled with a measuring circuit to measure heat conduction measured signals generated by the heat conduction-measuring unit, from which the concentrations of paramagnetic gases, which are contained in the gas sample, can be derived.
