Gas Exhaust Detector in EEX D Certified Box

VGS.AD-ES/IR

Gas Exhaust Detector with Infrared Sensor. In EEx certified container, suitable for installations in classified AD-PE range 4-20mA proportional output. Measuring range 0 to 100% LEL. Optional 3-relay output card. Zerointerferometer to control possible drifts. Continuous self-diagnosis of the system. 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.
