SICK GM32 In-Situ Gas Analyser – ATEX Zone 1 & Zone 2 Hazardous Area Gas Analyser
In-Situ Gas Analysers
SICK GM32
The SICK GM32 in-situ gas analyser is ATEX certified for gas analysis, measurement and monitoring in hazardous areas Zone 1 and Zone 2.
The GM32 in-situ gas analyser measures SO2, NO, NO2Â and NH3, as well as TRS components in Kraft pulp processes including pressure and temperature in the gas duct. It is direct, fast and does not require gas sampling or transport – This means control systems are able to work with actual values in real time. Self-monitoring ensures that the measured values are always reliable and in the case of a malfunction, an early warning will be shown.
For emission measurement of SO2 and NO, SICK GM32 is tested for suitability according to European standard EN 15267. An ATEX version (GM32-EX) with comprehensive safety functions and sophisticated system technology is also available, as well as the GM32 TRS-PE (PE = Pulp Emission) for TRS measurement in Kraft pulp processes.
SICK GM32-EX is used for gas analysis, measurement and monitoring in the oil, gas and chemical industry – the ATEX certified gas analyser is available in both cross duct and measuring probe versions.
BS EN 15267 specifies the performance criteria and test procedures for automated measuring systems that measure gases and particulate matter in, and flow of, the waste gas from stationary sources.
SICK GM32 Gas Analyser – Features
- Unaltered measured values in real time without altering the gas composition
- Short-term process deviations are detected
- Representative measurement by selection of cross-duct or measuring probe type
- Fast on-site service due to modular design
- Long maintenance-free intervals
- Cost-effective in-situ gas analyser — ATEX type also available
- Low cost of installation and operation, no test gases required
- Complete emissions measurement in kraft pulp process by way of simultaneous measurement of TRS components plus SO2, NO, NH33
➡ Did you know? T&D also distribute SICK level sensors, flow sensors, pressure sensors and temperature sensors.
