Proven Performance ----- Proven Technology ------ Proven Support
IR Combustibles Gas Detector Module, 5100-28-IT, from Sierra Monitor is Best of Class when it comes to providing the features demanded by instrumentation and safety professionals.
IT Series Gas Sensors Features
Sierra Monitor's IT series network enabled gas sensor modules are a top choice industry-wide. The IT gas sensors come with a wider array of features and integration options than any other gas sensor solution available.
- FM approval for performance and hazardous area operation - for safe and reliable operation
- Extended calibration frequency for low maintenance - for low cost of ownership
- SIL-2 Certified - for long term reliability
- Stainless Steel 316 or epoxy coated aluminum enclosures for ratings to meet application 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
- 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
- SMC Sentry bus interface - for interface with the Sentry system that has been in operation for many years
- HART Interface - fully complies to HART specifications
- %LEL or %Volume measurement - adaptable to user's needs
- Remote sensor configuration option - to meet specific application requirements
- Optional integral control relay pack - when higher amperage control relays are needed, but still integral to the enclosure without an external auxillary box
The FM Approved 5100-28-IT IR Gas Sensor Module utilizes Non-Dispersive Infrared technology to monitor for combustible gases (Methane and others). Output range is either 0-100% of LEL (default) or percent (%) by volume. This Module requires minimal maintenance with a calibration check once a year. Internal continuous self-diagnostics will automatically indicate any fault or optics problems.
Infrared technology has the benefits of:
- Reduced need for calibration and thus lower operating costs.
- Operates in high combustible gas and/or low oxygen environment
- Can operate in environments where catalytic bead poisons might exist
- Rapid recovery after exposure to high concentrations of hydrocarbon gas (exceeding 100% LEL)
