Smart Catalytic Bead Combustible Gas Detector

Combustible Gas DetectorThe Catalytic Bead Combustible Gas Detector Sensor Module is the Best in its Class with a package of benefits not found in any similar combustible gas sensor including:

  • FM approved 180 day calibration frequency
  • FM approval for both performance and hazardous area operation
  • Integral relay contacts plus 4-20 mA and Modbus output
  • Configurable for non-Methane gases

Sierra Monitor IT series gas detector sensor modules provide flexibility to meet the userís specific application requirements, low maintenance with long calibration intervals, well-proven sensors for long term reliability and third-party approvals.

The 5100-02-IT Combustible Gas Detector Sensor Module is loaded with the features demanded by today's safety and instrumentation engineers:

  • FM approval for performance and hazardous area operation - for safe and reliable operation
  • Extended calibration frequency of 180 days - for low maintenance and low cost of ownership
  • SIL-2 Certified - to meet safety integrity level requirements
  • Stainless Steel 316 or epoxy coated aluminum enclosures - to meet specific installation needs
  • Integral scrolling LED display - for ease of operation
  • Menu-driven system - for user-friendly configuration of alarm setpoints, calibration, maintenance and alarms acknowledge
  • Integral alarm relays for High, Low and Trouble - no need for external auxillary boxes
  • SMC Sentry bus interface - for interface with the Sentry system that has been in operation for many years
  • 4-20 mA output - enabling easy interface to common factory communications links
  • Modbus RTU serial interface - easy interface to the worlds most common industiral protocol from the company that provided the first hazardous gas detection system with Modbus interface
  • HART Interface - fully complies to HART specifications
  • Remote sensor configuration option - to meet unique application requirements

Model 5100-02-IT utilizes the proven, reliable, catalytic bead technology to monitor for combustible gases (methane and others). Output range is 0-100% of Lower Explosive Limit (LEL). This detector has minimal maintenance requirements and is Factory Mutual approved for six month calibration intervals. Internal, continuous self-diagnostics automatically detect and alarm any fault problems. The 5100-02-IT can be used as a 4-20 mA component or as a Modbus RTU node. For higher level system capability the module can interface directly to Sierra Monitorís Sentry Controller enabling system level Modbus serial communications, area and zone alarm management, extensive system diagnostic features, WebServer interface, and multiplexing sensor connections.
