LS4000 DIODE LASER ANALYZER | DS/LS4000-EN REV. G 3 — Introduction Application and design The LS4000 is an in situ cross-duct analyzer for measuring gas component concentrations. It applies the highly selective optical measuring principle of tunable diode laser (TDL) ab- sorption spectroscopy. The LS4000 is a stand-alone system which consists of a transmitter unit with a laser light source and a receiver unit with a photodetector. Both units are mounted opposite each other on the process pipe or stack and are connected by a junction box. Measuring principle – TDLAS 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 on the basis of the Beer-Lambert law. The influence of temperature and pressure variations is eliminated by dynamic automatic correction. — Specification Measurement components and measurement ranges NH 3 , H 2 O, NH 3 + H 2 O Min. / max. measurement range NH 3 0–10/0–1000 ppm Min. / max. measurement range H 2 O 0–10/0–50 vol.-% Max. abs. pressure 0.5–1.7 bar (7–24 psi) Max. temperature 450 °C (842 °F) Optical path lengths (OPL) 0.5–5 m (1.6–16.4 ft) H 2 O Min. / max. measurement range 0–10/0–50 vol.-% Max. abs. pressure 0.5–1.7 bar (7–24 psi) Max. temperature 450 °C (842 °F) Optical path lengths (OPL) 0.5–5 m (1.6–16.4 ft) Measurement range quantity 1 physical measurement range per sample component, 1 x transmission NOTICE • The analyzer performance characteristics have been determined according to IEC 61207-1:2010 “Expression of performance of gas analyzers – Part 1: General”. They are based on nitrogen as the associated gas. Compliance with these characteristics when measuring other gas mixtures can only be assured if their composition is known. • All specifications refer to an optical path length (OPL) of 1 meter, tested in ABB’s test and calibration jig. However, application-dependent variations may occur. The specific detection limit, minimum and maximum measurement range for a specific application will depend on the gas conditions (pressure, temperature and gas composition) and optical path length. Minimum measurement range, maximum pressure and maximum temperature cannot necessarily be realized simultaneously under all conditions. • The maximum pressure and maximum temperature given are physical (spectroscopic) limits. • Applications exceeding the above given spectroscopic limitation might be possible on request.
