The 301-EM-RFSA-CA2 from Honeywell is an infrared point gas detector tailored for reliable detection of hydrocarbons. Weighing 3.5 pounds, it operates on a nominal voltage of 24VDC, but it can function within an input range of 18 to 32 VDC. This device features a durable housing constructed from Type 316 stainless steel, combined with a black anodized aluminum flow housing, ensuring robust performance even in harsh environments.

With an IP rating of IP66/IP67, it is designed to withstand both dust ingress and water exposure, enabling it to perform effectively in a variety of settings. The detector is capable of measuring hydrocarbon concentrations within a range of 0 to 100% LEL, making it versatile for different applications.

Its sensitivity is matched by swift response capabilities, achieving a T50 response time of less than 3 seconds and T90 response time of less than 4 seconds for methane. Power consumption is efficient, with a maximum draw of under 5 watts. For ease of installation, the unit includes a 3/4-inch NPT mounting thread, allowing for straightforward integration into existing setups. This gas detector is an essential tool for environments where hydrocarbon detection is crucial.
