METHANE DETECTOR IN DUST-PROOF BOX

VGS.DU-ME/IR

Methane detector with Infrared sensor in EEx certified container. Proportional output 4-20mA. Measuring range 0 to 100% LEL. Zero Tracker to counter possible drifts. Continuous self-diagnosis of the system. Optional 3-relay output card. ATEX II2G certifications, and SIL1 certifications (EN50402 & IEC61508 1 to 7).

• Self-diagnostic procedure to control the detector main operational parts, both hardware and sensing element
• Zero point tracking to compensate possible drifts due to thermal or physical variations of the sensor
• Digital filter employed in the digital analysis of the analogue values sampled
• Hysteresis cycle applied to the outputs to eliminate continuous switching
• Watch-dog for the microprocessor control.
