Description
The Crowcon Xgard Bright is a fixed detector for flammable and toxic gas detection and oxygen monitoring. The Crowcon Xgard Bright is designed to provide ease of operation and reduced installation costs. The Xgard Bright provides analogue 4-20mA and RS-485 Modbus signals as standard, comes with an Alarm and Fault relay as standard as well as optional HART communications.
Using the Crowcon Xgard Bright lowers the cost of installation, and the 4-wire addressable implementation drastically reduces the 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.
The Crowncon Xgard Bright is available with MPS (Molecular Property Spectomete) technology, and is suited for a wide range of gases and sensor types.
