  • RKI S2 Series
  • S2 Non-Explosion Proof Toxic Assembly

    The RKI S2 series gas sensor/transmitters are highly reliable and very cost effective for the detection of common gas hazards. The S2 series are available for LEL, H2 Specific (LEL, and ppm), Oxygen, H2S, CO, and for a variety of toxic gases. The transmitters for LEL, H2 Specific, Oxygen, H2S, CO2, and Carbon Monoxide are explosion-proof with flame arrestors, and approved for use in hazardous areas (Class l, Groups B, C, D). An optional non-explosion proof version is available for oxygen, H2S, CO, and CO2 in non-hazardous atmospheres. LEL sensors are available using catalytic bead and infrared technologies.

    The toxic sensors are electrochemical type plug-in sensors, which provide high specificity, fast response, and long life. The plug-in design allows quick replacement in the field with no tools required. Toxic sensors are designed for use in Class I, Div. 2 hazardous locations. Sensors available for NH3, SO2, PH3, AsH3, and HCN.

    The S2 transmitters can be used either indoors or outdoors. The flame arrestors for the explosion-proof versions utilize a patented coating which make them water repellent. Splash guards are also available for use in very wet environments. An optional stainless steel junction box is available for corrosive environments.

    All of the S2 transmitters are designed to interface with RKI controllers, or with PLC/DCS systems.

    Features:

    • Available gases include
      LEL, H2S, CO, PPM H2, and CO2
      Toxic gases include NH3, SO2, HCN, and more
    • Infrared sensor for combustibles and CO2
    • Hydrogen-Specific now available
    • Patented water repellent sensor coating
    • 4-20 mA output
    • Optional stainless steel junction box
