LEL / H2 / O2 / CO / H2S Gas Sensors
The RKI direct connect series gas sensors are highly reliable and very cost effective for the detection of common gas hazards. The direct connect series are available for LEL, H2 Specific LEL, Oxygen, H2S, CO, CO2, and for a variety of toxic gases. The sensors for LEL, Oxygen, H2S, Carbon Monoxide, and carbon dioxide are explosion-proof with flame arrestors, and approved for use in hazardous areas (Class 1, Groups B, C, D). An optional non-explosion proof version is available for oxygen in non-hazardous atmospheres.
The direct connect sensors can be used in two different ways. The sensors can be mounted directly to the controllers as a complete stand alone system, or they can be mounted to explosion proof junction boxes for remote detection.
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 a class I, Div. 2 explosion proof area. Sensors available for Cl2, NH3, SO2, PH3, AsH3.
The direct connect sensors can be used either indoors or outdoors. The flame arrestors for the explosion-proof versions utilize a patented coating which make them water repellent. Also, splash guards are available for use in very wet environments, for some versions.
All of the direct connect sensors are designed to specifically interface with RKI controllers.
