Crowcon Xgard Bright Exd Gas Detector

Crowcon Xgard Bright Fixed Gas Detector

The Crowcon Xgard Bright is a flameproof (Ex d) fixed gas detector designed for the detection of flammable gases, toxic gases, and oxygen. Available in either high-grade aluminium alloy or 316 stainless steel, the Xgard Bright combines advanced sensing technologies with a local OLED display, addressable communications, and non-intrusive maintenance features to reduce both installation and operating costs.

The detector supports traditional 4-20 mA outputs as well as RS-485 Modbus communications, with optional HART capability for enhanced diagnostics and asset management.
