摘要:
A gas sensor arrangement comprises a first half-shell mateable with a second half-shell. The first half-shell has a detector receiving opening and radiation source receiving apertures. A gas measuring chamber is formed between the first half-shell and the second half-shell. The gas measuring chamber extends between the detector receiving opening and the radiation source receiving apertures. Concave mirrors are arranged around the radiation source receiving apertures. The concave mirrors are formed by inner surfaces of the first and second half-shells. Tubes extend from the concave mirrors to the detector receiving opening. The tubes are formed by the inner surfaces of the first and second half-shells. The inner surfaces are coated with a reflective material.
摘要:
The present invention relates to a method for measuring the presence and/or the concentration of an analyte by means of a gas sensor arrangement and to a corresponding gas sensor arrangement. The gas sensor arrangement comprises a radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas containing at least one analyte to be measured, and at least one radiation-detecting detector device which generates an output signal as a function of the presence and/or the concentration of the analyte. In order to be able to reduce the harmful effects of condensation water, which condenses in the gas measuring chamber, the gas measuring chamber according to the invention is heated before the measurement process, such that the wall of the gas measuring chamber assumes a temperature which lies above the dew point of the test gas.

摘要:
A gas sensor having a base, a light source having a lamp body, the light source being carried by the base, a first reflector associated with the light source, a detector for detecting the intensity of the light source, and a lampholder for play-free and immobile securing of the lamp body is disclosed.
摘要:
A gas sensor arrangement for detecting the presence or concentration of an analyte in a measuring gas comprises a gas measuring chamber having an inlet for receiving the measuring gas. A measuring radiation source is arranged in the gas measuring chamber. The measuring radiation source emits radiation in a non-uniform pulse sequence according to a signal from a controller. A radiation detector receives the radiation emitted from the measuring radiation source. The radiation detector sends an output signal to the controller for processing.

A method for producing thin silicon rods using a floating zone crystallization process includes supplying high frequency (HF) current to a flat induction coil having a central opening, a plurality of draw openings and a plate with a slot as a current supply of the HF current so as to provide a circumfluent current to the central opening. An upper end of a raw silicon rod is heated by induction using the flat induction coil so as to form a melt pool. A thin silicon rod is drawn upwards through each of the plurality of draw openings in the flat induction coil from the melt pool without drawing a thin silicon rod through the central opening having the circumfluent current.
