Diode laser analyser LS4000 Highest precision under harshest conditions

DiODE LASER ANALYZER LS40 00 The LS4000 is an in situ crossduct analyzer for measuring gas component concentrations. It applies the highly selective, optical measuring principle of tunable diode laser (TDL) absorption spectroscopy. The LS4000 is a stand-alone system and is approved for use in hazardous areas according to international standards. The device consists of a transmitter unit with a laser light source and a receiver unit with a photodetector. The two units are mounted opposite each other on the process pipe or stack and are connected by a junction box. Measurement made easy. The advantages...

How it works – measuring principle The LS4000 employs the optical measuring technique of absorption spectroscopy, which utilizes the fact that a specific gas absorbs specific light wavelengths. The light beam is emitted from a tunable laser diode located in the transmitter unit. The laser light passes through the process gas and strikes the photodetector in the receiver unit. The measured gas component present in the optical path absorbs the laser light, attenuating the light received. A sophisticated signal algorithm processes the amount of light attenuation and calculates the gas concentration...
