Details

The Crowcon Xgard Bright Fixed Multi-Gas Detector is a versatile detector offering flammable and toxic gas detection and oxygen monitoring, while providing ease of operation and reduced installation costs.

Choose from durable sensor options to suit your needs, such as MPS (10+ years), Long-life O2 (5 years) and IR sensors (10+ years) to prevent frequent sensor replacements and minimise operational expenses.

Lowering the cost of installation, the 4-wire addressable implementation drastically reduces cabling requirements. The large OLED display allows users to easily work with Xgard Bright during installation, calibration and routine maintenance without the need to open the housing.

Providing analogue 4-20mA and RS-485 Modbus signals as standard, Xgard Bright comes with an Alarm and Fault relay as standard as well as optional HART communications.

Next Generation Sensor Technology:

▪ MPS™ (Molecular Property Spectrometer) technology
- ▪ TrueLEL™ multi-gas accuracy
- - ▪ Free from risk of sensor poisoning
  - - ▪ No calibration or scheduled maintenance is needed
    - - ▪ Hydrogen ready
      - Versatile:
        
        ▪ Available in both high-grade aluminium alloy and 316 stainless steel
        
        ▪ Flammable and toxic gas detection, as well as oxygen monitoring options
        
        ▪ Choose from MPS™, Long-Life O2 and IR sensor options, all with long lifespans
        
        ▪ Choice of M20 or ½” NPT connection to suit your specific site requirements
        
        ▪ Low power usages (~3W max) helping reduce site-wide power consumption
        
        ▪ IP65 or IP66 rating (with weatherproof cap), allowing for use in areas subject to regular wash downs or exposed environments
        
        Ease of Installation and Operation:
        
        ▪ Addressable operation reduces the amount of cabling needed for multi-point installations
        
        ▪ Local display delivers gas level indication and device status at a glance
        
        ▪ Non-intrusive calibration eradicates the need to open the cover for calibration
        
        ▪ Plug-in type terminal blocks for reduced installation costs
        
        ▪ Configuration via magnetic key helps minimise the amount of time operators spend in a hazardous area
