InfraTec (www.InfraTec.de) is committed to extend its product line of pyroelectric detectors by new, highly innovative components which perfectly fit the latest markets requirements constantly. Since 2002 a wide range of current-mode detectors with integrated CMOS OpAmp instead of a JFET source follower has been brought on the market. These single and multi-color devices offer a signal voltage in the order of several hundred millivolts in NDIR gas analyzers and can easily be connected with micro
The progress in the miniature drive technology and high-precision mechanics makes it possible to use the classic filter wheel spectrometer in a much more competitive and compact form for multi component gas analysis. In contrast to the multi-color detectors, the measuring signal is available in a series through the very same optical and electrical channel. However, for a constant metering time period the modulation frequency of the IR detector rises with a higher channel number. InfraTec GmbH (
