HYDROGEN DETECTOR WITH DISPLAY IN EEX D CERTIFIED BOX

VGS.AD-H2-LCD

Hydrogen catalytic detector with Display suitable for installations in AD-PE classified environments. 4-20mA proportional output. 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.
