RKI Non-Explosion Proof Direct Connect Sensor (O2, H2S, CO)
Description
The RKI Non-Explosion Proof Direct Connect Sensors provide reliable, economical electrochemical detection of oxygen, hydrogen sulfide, and carbon monoxide in Class I, Division 2 hazardous locations. Designed for use with RKI Beacon controllers, these plug-in sensors mount directly at the controller enclosure or in remote junction boxes.
Compatible with Beacon 110, Beacon 200, and Beacon 410 controllers.
Applications: Petrochemical plants, Refineries, Gas plants, Offshore drilling platforms, Water & wastewater treatment plants, Pulp & paper mills, Gas, telephone, & electric utilities, Parking garages, Manufacturing facilities, Steel, Automotive
Key Features:
- Electrochemical plug-in sensors — no tools required for replacement
- Fast response
- Compatible with Beacon 110, Beacon 200, and Beacon 410
- Long sensor life
- Indoor/outdoor rated
- Water-repellent patented sensor coating (except toxics)
- Response Time: 30 seconds
- Life Expectancy: 5+ years with normal service
- 1-year warranty

Frequently Asked Questions
What does "Non-Explosion Proof" mean for this sensor?
A non-explosion proof sensor does not have a certified enclosure designed to contain an internal ignition. Instead, these sensors are rated for NEC Class I, Division 2 (Div 2) locations — areas where flammable concentrations are not likely under normal operations but may occur under abnormal conditions. Do not install these sensors in Division 1 areas; use explosion-proof sensors for those locations.
What gases do these sensors detect?
This product covers three sensor variants: Oxygen (O2, 0–25%), Hydrogen Sulfide (H2S, 0–100 ppm), and Carbon Monoxide (CO, 0–300 ppm). Each is ordered separately by part number, either sensor-only or with a junction box.
How do these sensors differ from the explosion-proof Direct Connect sensors?
The explosion-proof Direct Connect sensors (65-2514RK for O2, 65-2428 for H2S, 65-2438 for CO) are certified for Class I, Division 1 hazardous locations. The non-explosion proof variants (65-2494RK through 65-2499RK) are rated for Division 2 only. Choose the appropriate sensor based on the area classification of the installation point.
What OSHA standards apply to O2, H2S, and CO monitoring?
29 CFR 1910.146 requires atmospheric testing for O2 deficiency (below 19.5%), flammable gases, and toxic contaminants before confined space entry. 29 CFR 1910.1000 sets OSHA PELs for H2S (20 ppm ceiling) and CO (50 ppm TWA). Fixed monitoring supports continuous compliance verification in permit-required spaces and process areas.
How long do these sensors last?
The non-explosion proof Direct Connect sensors have a 5+ year life expectancy under normal service conditions — longer than some explosion-proof electrochemical types due to the less harsh enclosure environment. Regular bump testing helps confirm sensor function between scheduled replacements.
How does PK Safety support RKI fixed detection systems?
PK Safety services RKI Instruments fixed gas detection equipment in-house with factory-trained technicians — including sensor replacement, calibration, and Beacon controller diagnostics. Call 800.829.9580 to discuss service options.
