Gas Detection - UK Focus xi Next-Generation “Intelligent” Fixed-Point Gas Detector Launched
Crowcon Detection Instruments Ltd announce the next generation of intelligent gas detectors and transmitters: XgardIQ. XgardIQ is an intelligent and versatile gas detector and transmitter compatible with Crowcon’s full range of sensor technologies. XgardIQ is available fi tted with a variety of fl ammable, toxic or oxygen gas sensors or may be installed with a remote sensor housing up to 15 metres from the transmitter.
Providing analogue 4-20mA and RS-485 Modbus signals as standard, XgardIQ is optionally available with Alarm and Fault relays and HART communications. This comprehensive set of output interfaces ensures compatibility with virtually any control system from gas detection panels, to PLC’s, DCS’s and SCADA systems. HART communications 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.
XgardIQ offers powerful features that help to minimise the time that operators must spend in the hazardous area performing routine maintenance functions. Sensor modules can be simply and quickly “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 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.
XgardIQ utilises buttons and a bright OLED (organic light emitting diode) display rather than conventional magnets and LCD’s for confi guration and adjustments. The OLED display enables status checking at a glance and from a distance; whilst the use of buttons avoids the risk of special tools (e.g. magnets) being lost and thus resulting in aborted calibration attempts.
Crowcon’s unique “+ve Safety” feature confi rms the detector is operating safely using a bright blue LED and screen messages. XgardIQ automatically alerts operators to any irregular events that may affect product integrity such as the ambient temperature or gas concentration exceeding sensor limits. Such events may harm the sensor but would remain undiagnosed on conventional gas detectors: the sensor may be rendered insensitive to gas without warning the operator. When the detector is working safely the blue +ve Safety LED remains on constantly, if any abnormal operating conditions are detected the LED will fl ash and a warning message will be displayed.
XgardIQ deploys novel features to simplify commissioning. In major new-build projects instruments are often installed many months ahead of the planned commissioning date. Some sensor technologies have a limited shelf-life and thus may not be operational after a long period of installation without being powered. The operator may thus face signifi cant costs replacing sensors. XgardIQ can be installed without a sensor module, protected from the elements using a sealed ‘dummy’ module. Pre-calibrated sensor modules can then be supplied immediately prior to commissioning. The XgardIQ transmitter will automatically confi gure to the correct gas-type, scale and alarm levels when a sensor module is inserted.
“XgardIQ has been developed to address the challenges and objectives of operators in safety-critical applications and to deliver real user benefi ts” explains Andy Avenell, Senior Business Development Manager. “We spend a signifi cant amount of time talking to engineers and operators in oil and gas facilities, petrochemical and chemical plants and other high risk areas. The experiences and insight gained from such sites has been instrumental in the specifi cation development of XgardIQ.”
Inspecting Plants for Volatile Chemical Leaks

FLIR Optical Gas Imaging (OGI) cameras are preventative maintenance solutions designed to spot leaks in compressors, piping, fl anges and connections in chemical plants.
Based upon FLIR’s proprietary thermal imaging technology FLIR OGI cameras can rapidly scan large areas and pinpoint leaks of a wide range of volatile chemicals including Olefi ns (Ethylene and Propylene), Carbon Dioxide, Carbon Monoxide, Ammonia, Vinyl Chloride, Butadiene, Acetic Acid, Solvents and VOCs in real time. Being a non-contact measurement device the FLIR OGI cameras are ideal for monitoring chemical plant process areas/operations, such as Steam Crackers and Reformers, especially for components that are diffi cult to reach with contact measurement tools.
For More Info, email: email:
FLIR OGI cameras have a proven patented (US Patent US7649174) technology called High Sensitivity Mode (HSM) that enables you to detect the smallest of volatile chemical leaks. This is a function in the camera that dramatically enhances its sensitivity. As a result, the user can see smaller chemical gas leaks from a greater and safer distance compared to traditional ‘sniffi ng’ methods.
Literally thousands of components can be scanned per shift without the need to interrupt the process. It reduces repair downtime and provides verifi cation of the process. Above all it is exceptionally safe, allowing potentially dangerous leaks to be monitored from several meters away. FLIR OGI cameras will signifi cantly improve your work safety, enable environmental and regulatory compliance, help to improve the bottom line by fi nding leaks that essentially decrease profi ts and most importantly improve site and worker safety.
