XgardIQ is an intelligent and versatile gas detector and transmitter, fitted with a variety of flammable, toxic or oxygen gas sensors.
Installable with a remote sensor housing up to 15 metres from the transmitter and providing analogue 4-20mA and RS-485 Modbus signals, Crowcon’s new device is optionally available with Alarm and Fault relays and HART communications, which enables diagnostic checking and maintenance using industry-standard communications tools remotely or locally in the hazardous area. The HART feature also enables XgardIQ to be logged and monitored automatically on asset management systems. The set of output interfaces ensures compatibility with virtually any control system from gas detection panels, to PLCs, DCS’ and SCADA systems.
To minimise the time that operators must spend in the hazardous area performing routine maintenance functions, sensor modules can be “hot-swapped” without a hot-work permit, either for replacement with a new pre-calibrated replacement module, or for temporary removal to a safe area for calibration. Engineers thus avoid the need to carry compressed gas cylinders on-site and the sensor module can be tested and calibrated in the safety of a laboratory.
Users also have the option to perform a quick and simple bump test rather than full calibration to verify that sensors are fully operational. Using the ‘Speedy Bump’ and ‘Smart Bump’ options, users can perform interim safety checks in minimal time, and using the minimum amount of gas.
