RKI Instruments S2 Fixed Gas Sensor/Transmitter
Description
The RKI S2 Series fixed gas sensor/transmitters from RKI Instruments provide reliable, cost-effective detection of common gas hazards. Available for LEL, H2-specific LEL (LEL and ppm), oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2), and a variety of toxic gases, the S2 Series works indoors or outdoors and is designed for use with RKI controllers including the Beacon 110, Beacon 200, Beacon 410, and Beacon 800, as well as PLC/DCS systems. The plug-in sensor design enables field replacement without tools.

Frequently Asked Questions
What gas types can the RKI S2 sensor/transmitter detect?
The S2 Series is available for LEL combustible gas (general purpose and H2-specific), oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2, via infrared sensor), and a range of toxic gases including chlorine (Cl2), ammonia (NH3), sulfur dioxide (SO2), hydrogen cyanide (HCN), and more. Call 800.829.9580 to confirm availability for your specific gas hazard.
Which RKI controllers is the S2 sensor compatible with?
The S2 Series outputs a standard 4-20 mA signal and is designed to work with the RKI Beacon 110, Beacon 200, Beacon 410, and Beacon 800 controllers, as well as third-party PLC and DCS systems. This makes it easy to integrate S2 sensors into both new fixed gas detection installations and expansions of existing systems.
How are S2 sensors replaced in the field?
The S2 uses a plug-in sensor design that allows sensors to be replaced without tools directly in the field. This reduces maintenance downtime and eliminates the need to return the transmitter housing for sensor swaps. RKI's patented water-repellent sensor coating also extends sensor life in humid or wet environments.
What is the expected life of an S2 sensor?
Life expectancy depends on the sensor type and exposure conditions. LEL general-purpose sensors typically last 2–3 years with normal natural gas exposure; H2-specific LEL sensors last 3–5 years; CO2 infrared sensors typically last 5 or more years. Electrochemical sensors for O2, CO, H2S, and toxics typically last 2–3 years. Regular bump testing and calibration help identify sensor degradation before it affects performance.
Can PK Safety help select the right S2 configuration for my facility?
Yes. PK Safety is an RKI Factory Authorized Service Center with experienced technical staff. We can help match S2 sensor variants to your gas hazards, controller type, and area classification requirements. Call 800.829.9580 or contact us online to discuss your fixed gas detection needs.
