SGOES is based on infrared gas sensing technology. Providing continuous monitoring of pre-explosive concentrations of combustible hydrocarbon gasses and vapors, with a rapid response time of less than 5 seconds. SGOES has an explosion proof certified enclosure. SGOES is also certified by international accreditation agencies for SIL-2 rating.




Gas detector SGOES has a standard 4-20 mA,HART, RS-485 (Modbus RTU) and relay. The sensor is ideally suited for use in potentially hazardous gas / vapor-containing environments and withstands overload caused by the content of the measured component, more than 100% LEL. The SGOES is insensitive to the presence in the atmosphere of oxygen, nitrogen, carbon dioxide, carbon monoxide, ammonia, hydrogen sulfide. Ideally suitable for use in the oil and gas industry, as well as other areas where it is necessary to monitor the concentration of hydrocarbons. Gas detector SGOES is available in explosion-proof enclosure and certified in accordance with normative documents regulating the use of electrical equipment in hazardous areas IIA subgroup IIB, IIC, temperature classes T1-T4. And also has international approvals for use in hazardous areas and Class 1, Division 1 and 2, Zones 1 and 2. It gives the reading of the gas concentration and displays it on the LCD indicator. Integrated HART-communicator port allows to provide diagnostic and control of specific options and operability of the detector.
