Abstract Information :

Up until recently, gas detection technology hasn't really changed. More gases are being detected, but the basic technology has remained the same.

There are three basic types - Electro Chemical Cell (toxic), Catalytic (flammable) and Infra-Red (flammable and Carbon Dioxide).

Although good in their own right, apart from applying test gas, there is no real way of completely ensuring the sensing element is working. Calibration is sometimes only done every 12 months, so for the other 364 days of the year end-users only assume the system is working.

That is until now, with ATi's Gold Standard in gas detection - the daily AutoTest feature.

ATi's unique design generates a test gas to a known level and passes it over the sensing element on a daily basis. The firmware then looks for the sensor to respond to that level in a certain time, achieve the required level, and recover back to zero, all in a determined timespan. The result is then logged for future reference.

If the required performance is not met, the test automatically sequences again, for up to 3 attempts. If it still fails, a fault output is generated, which requires attention. This is not to say the sensor is not working (if a true release happens the sensor will still operate as required), the fault means the sensor is not performing within the determined criteria.

The Health & Safety industry are very keen to have this implemented across as many sites and applications as possible. Indeed European Standards are now leaning towards some kind of "proof testing."

As the ONLY manufacturer of this patented technology, it does bring the now available detection technology up a level... to the GOLD STANDARD.

With both safe area and ATEX approved equipment, toxic and flammable gas detection need never again be a guessing game.
