Infrared Combustible Gas Detector 5100-28-IT
Sierra Monitor’s infrared fixed gas detector, the 5100-28-IT, monitors combustible gases such as Methane and Propane, detecting and alarming users when gases reach between 0 to 100% lower explosive limit (LEL) concentrations.
The 5100-28-IT detector is based on infrared (IR) technology, an accurate and stable method of detection that requires low maintenance and can operate in highly combustible gas and/or low oxygen environments.
As the industry-wide top choice network-enabled fixed gas detector, the FM-approved 5100-28-IT detector utilizes Non-Dispersive Infrared technology to monitor for combustible gases. This technology also allows the detector to rapidly recover after exposures to high concentrations of hydrocarbon gas and operate in environments where catalytic bead poisons might exist. The detector also has minimal maintenance requirements and only requires one-year calibration intervals. Although the 5100-28-IT detector 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 detector 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 Detector 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.
GlobalCalTM
The 5100-28-IT supports GlobalCal™, our unique global calibration feature of the Sentry IT Controller. This allows a single technician to calibrate connected detectors from the Sentry IT Controller. With GlobalCal, the calibration happens at the controller level. Multiple detectors can be connected to a single controller, allowing groups of sensors to be calibrated at the same time. Standard gas is applied remotely, using permanently installed tubing, rather than direct delivery to the fixed gas detector.
Combined with the one-year calibration interval, GlobalCal reduces labor costs associated with calibration. The need to shut down active process areas for calibration consequently costs facilities thousands of dollars in lost production time. GlobalCal, with its remote and non-intrusive methods, allows production to continue during the calibration process, thus avoiding the costs of lost production. In addition, factory-authorized service technicians performing gas detector calibration save time and costs by remotely calibrating all gas detectors at once from the Sentry IT Controller.
