The Xgard Bright Crowcon stationary toxic gas sensor is a versatile platform that provides hazardous and flammable oxygen detection and monitoring, while providing ease of operation and reduced installation costs.

Providing the same Modbus 4-20mA and RS-485 signals as standard, the Xgard Bright comes with Alarm and Fault relays as standard as well as optional HART communication.

Reducing installation costs, the implementation of 4-wire addressing greatly reduces cabling requirements. The large OLED display allows users to easily work with Xgard Bright during installation, calibration and routine maintenance without having to open the case.

Description

I. Specification Xgard Bright fixed toxic gas sensor

Xgard Bright fixed toxic gas sensor

Generality:

  • This flame retardant (Exd) toxic gas detector is housed in a premium aluminum alloy housing. Certifications including gas and dust approvals for ATEX and IECEX with UL gas certification in progress.

Versatile:

  • Xgard Bright Crowcon stationary toxic gas sensor monitors flammable and toxic oxygen and toxic gases – Reduces training requirements on systems.
  • Choice of M20 or NPT connection – Supports multiple system requirements
  • Low Power Requirements (up to 3W) – Reduces system-wide energy consumption
  • IP65 or IP66 rated (with weatherproof cover) – Allows use in areas subject to frequent washing or exposure.

Easy to install and operate:

  • Addressing – Dramatically reduces the amount of cabling required for multisite installations
  • Local Display – Provides gas level indication, status and maintenance routine support
  • Non-Intrusive Calibration – with Xgard Bright Crowcon fixed toxic gas sensor eliminating the need to open the lid for calibration
  • Plug in type terminal blocks: Makes wiring quick and easy to reduce installation costs
  • Configuration via magnetic lock – Reduces the amount of time the operator spends in the hazardous area.
