A combustible gas detection system in which remotely located combustible gas sensors of the analog type are monitored by a central controller. The sensor analog data is converted to digital data and transmitted to the controller. The controller tests the integrity and validity of data received from the sensor, identifies the nature of any faults therein and vocally signals the cause of such ...
A Guide to the Characteristics of Combustible Gases and Applicable Detection Technologies Published by the Technical Staff of GENERAL MONITORS 26776 Simpatica Circle Lake Forest, California 92630 Tel. +1-949-581-4464 Fax +1-949-581-1151 FUNDAMENTALS OF COMBUSTIBLE GAS DETECTION
In combustible gas detection you want to know, if the atmosphere is combustible or not. Therefore the gas detector is normally calibrated to 0 – 100 % LEL, where the alarm thresholds are set to low concentrations such as 10 % LEL and 20 % LEL. This allows the plant safety team to take precautionary measures before the atmosphere can get explosive.
We can offer a wide range of flammable gas detection instruments for hazardous areas applications that measure hydrocarbon gases at the %LEL and %vol levels. Product options include explosion-proof and intrinsically-safe designs and the product offering includes technology options for both non-dispersive infrared and catalytic bead sensing methods.

Natural gas fired engines that drive compressors for gas gathering are required to have gas detection. This is because the ignition systems are general purpose devices used in Class 1 Zone 2 areas. Traditionally, catalytic bead gas detection has been used for the detection of combustible methane and other hydrocarbon gases.
Our emphasis has always been to ensure that we have sufficient spares and service capability to ensure any gas detection system was maintained in service and accurately calibrated, ensuring worker safety was never compromised. The purchasers of Gastech products trust themselves and their personnel to our equipment, depend on us for training, and count on us for excellence in service and ...
The TGAES Gas Detector is an open path infrared gas detection system that provides continuous monitoring of combustible hydrocarbon gas concentrations at a distance of 15 to 650 feet (5 to 200 meters). No direct electrical connection between the two modules is required. In some applications, one TGAES detection system can provide protection equivalent to as many as eight point detectors.
Combustible, toxic, gas leak and oxygen depletion detectors for personnel, process and asset protection. Det-Tronics has designed and manufactured certified gas detection solutions for hazardous industrial environments for over 30 years. During this time, we have developed a broad line of innovative and reliable gas detectors, with our acoustic and line-of-sight models winning exida safety awards.
A method for detecting combustible gases or vapours using a combustible gas sensor or pellistors includes the steps of keeping the combustible gas sensor or the pellistor beads inactive until an oxygen sensor indicates a variation from a reference level of oxygen, such variation representing the potential presence of combustible gases or vapours.
Consider available gas detection methods for LNG terminals. The natural gas liquefying process presents a number of major hazard potentials. Liquid released into the open will turn into gas leading to fire or explosion. A variety of gas detection methods are …
Flammable Gas Detectors Used extensively in Petrochemical, Oil and Gas industries, flame detectors can reliably detect a wide range of hydrocarbon and non-hydrocarbon based fires.
