Crowcon XgardIQ Smart Fixed Point Gas Detector
The Crowcon XgardIQ is the next generation of fixed gas detectors from Crowcon and has been manufactured to enhance site safety and minimise the time workers must spend in hazardous areas exposed to harmful gas.
The fixed gas detector is versatile, compatible with Crowcon’s full range of sensor technologies and is available fitted with a variety of flammable, toxic or oxygen gas sensors.
Andy Avenell, senior business development manager at Crowcon, said while explaining the product development;
“We spend a significant 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 specification development of XgardIQ.”
When lives and real estate are at stake, the Crowcon XgardIQ provides reliable notification system of the presence of harmful, explosive and flammable gases. This minimises the amount of time that a worker must spend in a hazardous area.
Hot Swappable Sensors
The XgardIQ minimises the amount of time spent between swapping sensors and performing routine maintenance. The sensors can be ‘hot-swapped’ without the need for a hot work permit. The old module can be replaced with a new pre-calibrated one or removed for testing and calibration in a safe area.
Crowcon XgardIQ Fixed Gas Detector Product Interface Features
Versatile sensor options
The modern plant environments often require a varying degree of gas detection diversification. The Crowcon XgardIQ can offer this versatility and wide application of gas detection with a single product.
Positive safety
Crowcon’s unique positive safety feature reassures operators that the XgardIQ is functioning properly by alerting when there is any irregular events that may effect the sensors performance. This puts the XgardIQ ahead of other sensors that may otherwise cease to function when exposed to extreme environmental conditions.
When the detector is working safely, the bright blue +ve safety LED remains constantly turned on. If there are any abnormal operating conditions that are detected, the +ve LED warning light will flash and a warning light message displayed.
Improved safety and flexible signal outputs
Crowcon XgardIQ Gas Detector Display And Input
The Crowcon XgardIQ is an intelligent and versatile fixed point gas detector providing comprehensive and powerful output signal options. These include an analogue 4-20mA signal with auto sink/source detection feature and RS-485 Modbus communications provided as standard.
The XgardIQ minimises the time that personnel have to spend in potentially hazardous areas by using simple, hot-swappable sensor modules. Sensors can be both bump tested or calibrated in-situ or alternatively can be removed in seconds using one hand. They can then be replaced with pre-calibrated sensors or re-calibrated in a safe area.
All functions of the Crowcon XgardIQ and any adjustments can be made via the integral keypad without the need to purchase and special tools or equipment.
Compatability
The XgardIQ is compatible with virtually any control system including gas detection panels, PLC’s, DCS’s and SCADA systems. This makes the detector easier to install and reduces costs associated with installation.
When calibrating the XgardIQ sensor, calibration gas must be applied used the calibration cap also available from Crowcon. Typically, a flow rate of 0.5 litres per minuter is appropriate however this may vary for different sensor types.
Calibration can be performed with a suitable gas concentration from 10% of the scaled sensor range to 100% of the maximum sensor range. The minimum calibration gas concentration that can be used is 10% of the scaled range.
