| 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, and CO for a variety of RKI's controllers. All sensors
are explosion-proof with flame arrestors, and approved (optional
non-explosion proof version available for oxygen for use in 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 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. All of the direct connect sensors are designed to specifically interface with RKI controllers. |
