Crowco Xgard Bright is a versatile platform fixed gas detector offering flammable and toxic gas detection and oxygen monitoring, while providing ease of operation and reduced installation costs. Providing analogue 4-20mA and RS-485 Modbus signals as standard, Crowcon Xgard Bright comes with an Alarm and Fault relay as standard as well as optional HART communications.

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 install, calibration and routine maintenance without the need to open the housing.

This flameproof (Exd) detector is housed within our high-grade aluminium alloy case. Certifications include gas and dust approvals for ATEX and IECEX with UL gas certification in progress.

Crowcon is pioneering advanced molecular property spectrometer (MPS™) sensor technology that detects and accurately identifies over 15 different flammable gases in one device. Now available in Crowcon’s flagship Xgard Bright fixed detector.

KEY FEATURES Xgard Bright

Meet the next generation of flammable gas detection

The Xgard Bright is now available with MPS (Molecular Property Spectrometer™) technology

  • Sensor Poisoning is solved
  • Zero calibration for 5 years
  • TrueLEL™ multi-gas accuracy
  • Hydrogen ready

Versatile:

  • Flammable and toxic gas detection and oxygen monitoring – Reducing training requirements across sites
  • Choice of M20 or ½”NPT connection – Supports multiple site requirements
  • Low power requirement (~3W max) – Reducing site-wide power consumption
  • IP65 or IP66 rating (with weatherproof cap) – Allows use in areas subject to regular wash downs or in exposed environments

Ease of installation and operation:

  • Addressable – Drastically reduces the amount of cabling needed for multi-point installations
  • Local display – Delivers gas level indication, status and supports maintenance routines
  • Non-intrusive calibration – Removes the need to open the cover for calibration
  • Plug in type terminal blocks – Making wiring quick and easy reducing installation costs
  • Configuration via magnetic key – Reducing the amount of time operators spend in a hazardous area

Reducing the time operators spend in potentially hazardous areas:

At Crowcon we recognize the challenges faced and processes required every time an operator enters a facility or site that has been classified as a hazardous area. Permits are needed, specific training and equipment are required  and procedures have to be followed. This consumes resources, which ultimately increases the cost of operations.

Xgard Bright has been designed with this in mind, making routine calibration and maintenance operations quick and simple to reduce the time operators spend in hazardous areas:

  • Non-intrusive calibration – Zero and calibration functions (plus setup, tests and adjustments) are performed via the display using the magnetic wand, without needing to open the housing reducing the need for a hot work permit
  • OLED display – The brightly illuminated “organic light-emitting diode” display clearly indicates the gas level and units as well as providing comprehensive menus for setup and diagnosis. In low ambient light conditions, such as a dark room, the OLED display achieves a much higher contrast ratio than an LCD used on conventional gas detectors
  • Addressable communications – Xgard Bright detectors can be connected on an addressable network using RS-485 Modbus. This option significantly reduces cable and installation costs, while increasing the flexibility and functionality of the wider system
