Crowncon Xgard Bright
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.
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
