Methane Gas Detection Systems

Print Friendly, PDF & Email

Designed for “Green” Environmentally Friendly Alternative Fuel Vehicles. 

Major heavy-duty truck manufacturers have developed engines that run on CNG (compressed natural gas) and LNG (liquefied natural gas).

Methane is a potentially explosive by-product of LNG and CNG Fueled Engines.

The Xintex® line of products include everything you need for outfitting a complete and safe methane gas detection system:

 

Detector

Sensors

Remote Status Indicator Panels

Test Kit

Cable Splitter and Connections

Methane Gas Detection System Example

Methane Gas Detector S2B-M-X2

 

CNG and LNG fume detector for trucks

The Xintex® Methane Gas Detector / Monitor, Model S2B-M-X2-Display, constantly monitors the level of highly explosive methane and goes into alarm prior to a dangerous situation occurring.

This advanced micro-processor, state-of-the-art Methane Gas Detector is incorporated into the design and re-design of vehicles using CNG or LNG as a fuel.

Product Design: The stylish contemporary design of the Xintex Methane Gas Detector Monitor is ideal for installation into a dash, or similar panel. The 2 1/8” round housing, with 2 5/8” square bezel compliments the interior design of trucks and buses.

Advanced electronic circuitry utilizes our exclusive digital signal, eliminating the necessity of purchasing proprietary cabling to sensors and panels. Equipped with Deutsch Connectors, with heat shrink and boots. Installation at the factory or aftermarket provides cost savings, versus competitive models. Standard 18 gauge insulated wiring may be incorporated into wiring harness. All connections are through Deutsch Connectors for a plug and play installation, thus saving costs and time at the factory. Aftermarket installations are made easy as heavy bulky proprietary cabling is not required.

Optional Xintex wiring harness for sensors and remote status panels equipped with Deutsch Connectors are available at additional cost where desired.

 Features:

  • Two Zones: Cab and Engine Connect up to 2 Methane Gas Detection Sensors per zone, with Splitter01-D (sold separately)
  • Easy view Colored L.E.D.’s Green = System is okay and fully functional; Yellow = System fault; Red = Elevated Methane Level Detected
  • Initial illumination at 20% of the L.E.L., and remains on, until a safe level is restored- 1 amp Output relay opens at 50% of the L.E.L. (Horn optional or customer supplied)
  • Membrane Style Test and Silence Buttons
  • Test Button for weekly system testing
  • Reset Button, silences alarm for 30 second intervals

Methane Gas Detection Sensors

Xintex Methane Gas Detection Sensors are designed for specific reaction to elevated levels of methane and natural gas, while ignoring other hydro carbons, thus insuring faster response time and elimination of false alarms due to sulfated batteries, asphalt fumes on recently paved roads, elevated gasoline fumes from neighboring parked trucks, etc.

All sensors are pre-conditioned in our temperature and humidity controlled rooms for a minimum of 7 days prior to final calibration processes
