摘要： A gas concentration-measuring device makes it possible to measure gas components in a gas sample. An interferometer, based on a dual-band Fabry-Perot interferometer (1), is provided with a transmission spectrum that can be set by a control voltage (38). The control voltage (38) of the dual-band Fabry-Perot interferometer (1) is synchronized over the course of time with the activation and deactivation of the radiation sources (11, 12).

A gas sample a measurement element (1) is arranged in the region of an opening on a circuit board (11). To convey gas a duct (16, 17) is formed in each of two metal bodies, which surround the measurement element (1) and serve as magnetic poles.

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.

摘要： A measuring head for the determination of the concentration of a paramagnetic gas in a gas sample has first and second housing parts (21, 2) made of a steel alloy for accommodating a magnet coil body (4, 5) each. The magnet coil bodies extend concentrically around the central axis of each housing part (21, 2). Metallic bars (31, 3), which are used as magnet poles for the measuring head, are located at spaced locations with a defined air gap in the assembled state of the measuring head. The bars are arranged in the center of the measuring head in the area of the central axis of the housing parts (21, 2). A sample gas cuvette support (6) is provided in the air gap between the housing parts (21, 2) for positioning a sample gas cuvette holder (1).

摘要： The invention is directed to an apparatus for optically evaluating colorimetric coloration zones automatically wherein not only a single testing tube but also a plurality of reaction zones applied one behind the other to a common carrier can be evaluated. The least quantity of indicator substances for the coloration zones is used and an adequate signal intensity with the least possible consumption of power for the optical signal evaluation is attained. At the same time, the sensitivity to faults is reduced. Such an apparatus includes transmission as well as receiving units on a common mounting carrier. The light of the transmitting unit is conducted via a light conductor through the region of the reagent carrier which is transmittent and the coloration of the channel-shaped reaction zones of the carrier is detected in transmission and reflectance.

摘要： A device is provided for measuring the velocity of flow of a fluid in a respiration system and includes a first thermal sensor element (5) provided with a controllable heating element (50) and a second thermal sensor element (6). The thermal sensor elements (5, 6) are arranged at spaced locations from one another at a path of flow, so that a thermal signal generated by the first sensor element (5) with the heating element (50) is transmitted to the second sensor element (6), and the second sensor element (6) is designed to detect the thermal signal from the fluid flow. The second sensor element (6) is connected to the first sensor element (5) via feedback (12) which triggers another thermal signal. A controlling and analyzing device (13, 15) is connected to the sensor elements (5, 6) to start the generation of a first thermal signal and to read and analyze the signal frequency as an indicator of the velocity of flow.
