Product description

XgardIQ is an intelligent and versatile gas detector and transmitter compatible with Crowcon’s full range of sensor technologies. XgardIQ is available fitted with a variety of flammable, toxic and oxygen gas sensors and provides a bright OLED display with clear and comprehensive status information in a range of languages.

Confidence with Positive Safety

Bright LEDs indicate detector status at a glance; the unique Positive Safety LED confirms the detector is operating safely and alerts operators to any irregular events that may affect product integrity such as the ambient temperature exceeding sensor limits. When working safely, the blue LED remains on constantly. If any abnormal conditions are detected the LED will flash and a warning message will be displayed.

Flexible signal outputs

XgardIQ provides comprehensive and powerful output signal options; analogue 4–20mA signal with auto sink/source detection feature and RS-485 Modbus communications are provided as standard. Alarm and fault relays featuring heavy-duty changeover contacts, rated 230Vac 5A, are available at purchase or may be added at any time after installation. HART communications can be provided both over the analogue signal and via local I.S. terminals for diagnostics via any HART asset management system or hand-held device.

Improved safety

XgardIQ minimises the time personnel spend in potentially hazardous locations by using simple hot-swappable sensor modules. Sensors can be bump tested and calibrated in-situ or removed in seconds using one hand, and either replaced with a pre-calibrated sensor module or re-calibrated in a safe area before being refitted. All functions and adjustments can be made via the integral keypad without the need for special tools or hot-work permits.

Rugged and robust

ATEX and IECEx certified for use in Zone 1 and Zone 2 hazardous areas, XgardIQ has been designed for long-life operation in extreme environments. Featuring a rugged 316 stainless steel construction and a wide operating temperature range from –40°C to +75°C, XgardIQ is suitable for the most demanding applications.
