Solid State H2S Gas Sensor Module 5100-15-IT

Sierra Monitor’s 5100-15-IT module monitors Hydrogen Sulfide (H2S), a foul toxic gas capable of killing facility personnel.

The 5100-15-IT module is based on solid state (semiconductor) nanotechnology, a simple and robust method of detection capable of detecting low points-per-million (ppm) levels of gases.

Utilizing the solid state NTMOS (nanotech metal oxide semiconductor) technology, the 5100-15-IT module has a long life cycle and fast response times. For higher level system capability, the module can interface directly to Sierra Monitor’s Sentry Controller to enable system level Modbus serial communications, area and zone alarm management, extensive system diagnostic features, WebServer interface, and multiplexing sensor connections.

The Solid State H2S Gas Sensor Module 5100-15-IT is approved and certified by a variety of third party agencies, including ATEX and SIL-2. These approvals and certifications assure our customers that we carry only the highest quality of products.

GlobalCal™

The 5100-15-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 sensors 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.

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.
