The early detection of vapours leakages and flammable and explosive gases is a peremptory necessity in the chemical and petrochemical plants, in the storages of hydrocarbons, solvents, etc. For that, three methods are commonly used: The catalytic combustion, the infra-red in specific measurement ...

For several years, the technical specifications require Infra Red technology for flammable point detectors. The bad results of catalytic point detectors in UK sector, participated to the development of infra-red technology and to the replacement of all catalytic points in specifications.
In a ...

It is customary for the response time of a flammable or toxic gas detector to be introduced as a major criterion of choice during a technical evaluation. The European norm clearly states that a flammable point gas detector (catalytic or Infra red type) must comply with a response time to T50 ...

With an article published in 1993, we developed principles, advantages and limits of three available tools for flammable gas detection:

- point catalytic type
- point infra red
- open path infra red

GENERAL MONITORS, along with other manufacturers, have developed new ...

New technologies but also and principally low prices, opened door to an important confusion which is extremely dangerous when safety equipments are concerned. In the past safety equipments had to use proven reliability and availability. New and/or cheap technologies were studied, also evaluated and ...
