RKI Methane (CH4), 0-100% LEL, IR Explosion-Proof Direct Connect Replacement Sensor
- SKU:
- 61-0190RK-CH4
Description
The RKI 61-0190RK-CH4 is a genuine RKI infrared detector designed for measurement of Methane (CH4) from 0–100% LEL. It uses infrared (IR) sensing technology and features an explosion-proof direct-connect design for compatible RKI fixed gas detection systems.
The detector is equipped with a 3/4" NPT nipple for installation and is supplied as the detector/sensor assembly only. A transmitter and junction box are not included.
RKI documentation identifies the 61-0190RK-CH4 for compatible fixed-system applications including the M2A Transmitter, Direct Connect systems, and select Multi-Point / Tri-Head detector configurations.
Important: This is the Methane (CH4) 0–100% LEL version. It should not be confused with the 61-0192RK-CH4 0–100% volume methane detector or the 61-5039RK-CH4 non-explosion-proof plug-in methane sensor.

RKI 61-0190RK-CH4 is used in compatible RKI fixed gas detection systems requiring an explosion-proof infrared methane detector.
RKI documentation identifies this exact detector for use with:
- RKI M2A Transmitter – compatible IR Methane configurations
- RKI Direct Connect Fixed Gas Detection Systems
- RKI 65-2481RK-01 Multi-Point Detector – IR CH4 configuration
- RKI Tri-Head Gas Detector Systems – IR CH4 configurations
- Beacon 110 – compatible Direct Connect configurations
- Beacon 200 – compatible Direct Connect configurations
- Beacon 410 – compatible Direct Connect configurations
Important: Do not confuse this detector with:
- 61-0192RK-CH4 – Methane (CH4), 0–100% volume, IR explosion-proof direct-connect detector
- 61-5039RK-CH4 – Methane (CH4), 0–100% LEL, IR plug-in replacement sensor
- 61-0190RK-HC – Hydrocarbon (HC), 0–100% LEL, IR explosion-proof direct-connect detector
The 61-0190RK-CH4 contains a non-replaceable internal sensing element. If sensor replacement is required, the complete detector assembly is replaced.
Always verify the complete RKI part number, target gas, measurement range, and system configuration before ordering.
