Combustible Gas Detectors

Combustible gas detectors utilize both catalytic bead sensors and infrared sensors to provide reliable readings in any application. These units are designed to detect a wide range of gases, including acetylene, butane, hexane, methane, propane, and many more.

R.C. Systems offers: single point  and open path gas detection We have the experience and expertise to find you the combustible gas detector that best fits your application needs.

 
 

Single Point Gas Detectors

Our single point gas detectors offer a wide range of features.

Catalytic Bead Gas Detectors

Catalytic bead combustible gas sensors consist of a reference bead and an analytic bead wired into a Wheatstone bridge circuit. In these combustible gas detectors, a small amount of gas is burned on the analytic bead causing it to get hotter and increasing the gas detector’s resistance and voltage drop. This creates an imbalance of the bridge circuit that is proportional to gas concentration. Catalytic sensors are easy to operate and install, and they are easily customizable to many applications.

Smart Sensor and Millenium Infrared (IR) Gas Detectors

IR explosive gas detectors use band pass infrared light in analytical and reference wavelengths through a volume of gas. Both wavelengths’ paths are measured, and the light is reflected to IR detectors. The target gas reduces the intensity of the analytical beam but not the reference beam, much like smoke affecting visible light. The combustible gas sensor’s reference detector monitors the intensity of the two infrared sources and compensates for the loss of signal caused by dirty optics or source aging. IR explosive gas detectors require minimal to no routine calibration and will operate continuously in the presence of gas.
 

Open Path Gas Detectors

Open path gas detectors cover a wide area, and a method to pick up multiple leaks, and have a very high response rate. They feature beam block warning, have no unrevealed failure modes, and indicate the gas hazard size. R.C. Systems’ Quasar 900 open path gas detector utilizes the very latest in open path infrared technology to detect a wide range of hydrocarbon gases including alkanes (methane to hexane) and ethylene. These units can be custom-tailored to your high-risk installation.
