Styrene Detector in EEX D Certified Box

VGS.AD-STI

Styrene detector suitable for installations in AD-PE classified environments. 4-20mA proportional output. Centrally connected to a dedicated module. Possible use with relay board on dual threshold switchboard 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.
