BUTYL ACETATE CATALYTIC DETECTOR IN EEX D CERTIFIED BOX

VGS.AD-AB

Butyl Acetate 4-20mA catalytic detector, suitable for AD-PE classified installations. Proportional output 4-20mA. Connected to centrally powered modules. Possible use with relay board on dual threshold switchboards with pre-alarm at 10mA and alarm at 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.
