Xgard Bright: now available with MPS technology

Overview

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.

Meet the next generation of flammable gas detection

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

• Sensor Poisoning is solved
• Calibration is over
• 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

 

Building on over 50 years of gas expertise, Crowcon is pioneering advanced molecular property spectrometer (MPS™) sensor technology that detects and accurately identifies 15 different flammable gases in one device
