Crowcon XgardIQ Intelligent Gas Detector and Transmitter
Crowcon fixed-point detectors have been proven in many arduous environments, including oil and gas exploration and production, petrochemicals, water treatment, chemical plants and steel mills. XgardIQ provides fail-safe detection of a very wide range of gases and vapours. 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 (sold in English as standard). 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.
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.
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 the tool provided, and either re?placed with a pre-calibrated sensor module or re-calibrated in a safe area before being re-fitted. All functions and adjustments can be made via the integral keypad without the need for special tools or hot-work permits. 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.
If XgardIQ is to be installed months ahead of scheduled commissioning, it can be supplied without a sensor module to avoid the possibility of the sensor being poisoned or expiring whilst inactive. The transmitter is supplied with a dummy sensor module to maintain dust and water ingress protection and sensor modules can be delivered and installed prior to commissioning.
Key Features:
Positive Safety indicator – Status checking at a glance and from a distance. OLED display – Bright, clear display indicates gas level even in dark locations. Buttons – Functions performed via buttons, without the need for special magnets or tools. Event log – Clear history of detector use. Hot-swap sensor modules – Easily removed or replaced using the tool provided without requiring hot work per?mit or special tools. Auto-sense function – Automatically detects whether the control system is 4-20mA current sink or source, saving time and faults. Auto-configure function – Detects when sensor module is plugged in and uploads the appropriate gas type, range, units and alarm levels. Smart Bump and Speedy Bump test – Sensor health and response verified quickly and easily following simple on-screen instructions. Detector automatically provides a reminder when next bump test is due. Calibration due warning – Automatically reminds the user when calibration is due to ensure sensors remain accurate at all times. Sensor range selection – Users can set the full-scale range of the sensor via the display menu according to site or specific location requirements.
