R125 Gas Detector in Dust-Proof Box

VGS.DU-R125

R125 gas detector with Infrared sensor. In EEx Zone 2 certified container. Proportional output 4-20mA. Zero Tracker to counter possible drifts. Continuous self-diagnosis of the system. Optional 3-relay output card. Operating voltage 12-24Vdc. Certificate ATEX II3G. Can be connected to addressable control panel through suitable module. Can be used with relay board on double threshold control panel with pre-alarm 10mA and alarm 20mA.

• 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.
