FOR LOWER EXPLOSURE LIMIT MONITORING OF FLAMMABLE GASES • Fast response time (T90 in 1,4 sec.) • High reliability • Single or multipoint monitoring

The sample gas stream passes through an analytical cell (optical path). The infrared light emitted by the source is absorbed by the sample gas in the cell and captured by a receiver. The decrease in intensity between the emitted and captured light is proportional to the concentration of the solvent. Signal detector sourrp'W' Beamsplitter GAS FLOW Compensation detector Flameproof Chamber The infrared system is the cost-effective solution for simple solvent mixtures in low temperature applications.

HOW IT WORKS The sample is continuously drawn from the oven or duct, routed through the analytical unit for measurement, and safely returned nearby the same sampling point. Concurrently, data is transmitted to the control unit, which automatically manages concentration thresholds and triggers system status contacts whenever necessary. Integration: The control unit seamlessly interlocks with the plant's PLC logic, ensuring immediate and reliable response.

LEL MONITORING SYSTEMS COMPARISON Features / Norms Response Time Response time in 5 seconds. Response time in 1,4 seconds. Calibration & Maintenance Expensive and frequent calibration/maintenance required due to Span and zero drifts.
