Intended purpose The GM32 gas analyzer serves for continuous measurement of gas concentrations of SO2, NO, NO2 and NH3 as well as the reference values of temperature and pressure in industrial plants. As in-situ measuring device, the GM32 determines the measured values directly in the gas carrying duct from the measuring gas spectrum. Versions The GM32 provides simultaneous multicomponent measurement (combinations of measuring components) as well as single-component measurement. The following measuring probes are available for optimized adaptation of the measuring device to the measuring point: • GMP measuring probe with open measuring aperture for use with high dust loads in the measuring gas • GPP measuring probe with gas-permeable ceramic filter in the measuring gap. The GM32 gas analyzer comprises the following components: • Sender/receiver unit • Measuring probe, GMP or GPP • Connection unit • Purge air unit (for GMP probe) • Mounting flange • SCU operating unit (option) Simultaneous or individual measurement of SO2, NO, NO2 and NH3 as well as temperature and pressure DATA SHEET GM32 Measuring Probe Version certified

2 GM32 | SICK Project planning and preparation Project planning of the measuring device is very important to ensure unrestricted function and efficient start-up. The main requirements and preparations at the installation site as well as a wiring example with connection options are described in the following. Requirements at the installation site • Determination of measuring point – Provide for an unhindered inlet and outlet paths. – Provide for calibration openings at easily accessible places. Ensure that the measuring device and the calibration probe do not influence each other; provide...
