The Amphenol IR14BD with Air Quality Sensors 19mm 0-100% LEL AcetyleneInfraGasSen is an integrated package solution of a sensing element, an amplifier, and a calibration resistor. It is equipped with a gas-sensitive membrane that detects acetylene LEL levels between 0-100% and amplifies the signal directly to analog output. The device has a robust construction, operating temperature of -20°C to +85°C, and a low power consumption of = 5 mW. It has an LED indicator which provides an early warning status for high levels of acetylene LEL. It is a cost-effective and reliable solution compared to its competitors for air quality monitoring in places like closed environments, underground sites, laboratories, warehouses, and factories. It is also RoHS compliant and has a 2-year warranty.
