Fixed Type Gas & Flame Detection

Infrared Combustible Gas Sensor Module 5100-28-IT

Sierra Monitor’s infrared fixed gas sensor, the 5100-28-IT, monitors combustible gases such as Methane, Propane, Hexane and others, detecting and alarming users when gases reach between 0 to 100% lower explosive limit (LEL) concentrations.

The 5100-28-IT module is based on infrared (IR) technology, an accurate and stable method of detection that requires low maintenance and can operate in high combustible gas and/or low oxygen environments.

As the industry-wide top choice network-enabled fixed gas sensor, the FM-approved 5100-28-IT module utilizes Non-Dispersive Infrared technology to monitor for combustible gases. This technology also allows the module to rapidly recover after exposures to high concentrations of hydrocarbon gas and operate in environments where catalytic bead poisons might exist. The module also has minimal maintenance requirements and only requires one year calibration intervals. Although the 5100-28-IT module can be used as a stand-alone sensor, it can also 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 Monitor’s Sentry IT Controller to enable system level Modbus serial communications, area and zone alarm management, extensive system diagnostic features, WebServer interface, and multiplexing sensor connections.

The fixed Infrared Combustible Gas Sensor Module 5100-28-IT is approved and certified by a variety of third party agencies, including UL, FM, SIL-2, ATEX, CSA, and ABS. These approvals and certifications assure our customers that we carry only the highest quality of products.
