How do we periodically calibrate our sensors?
Thanks to our calibration kit it will be always possible for our sensor to work accurately. The TC 011 kit (for industrial sensors) and TC 012 (for domestic sensors) will have always to be supported by these articles: Gas cylinder valve BO 301 and gas baloon or an India rubber reserve gas container PA 020.
In addition it will be necessary to be also equipped with a gas cylinder (a gas which matches with the sensor characteristics) in order to run the tests.
If I want to make a detection methane or Lpg plant in a domestic environment, what articles do I need?
You will need a detection central unit SE 230 Km (Methane) or SE 230 Kg (LPG). This central unit could be supported by the SE 296 Km (methane) or SE 296 Kg (Lpg) sensor whether you need to monitor more than one room. This sensor could work together with an unlimited number of equivalent sensors in a number equal to the environments in which they will have to be installed. .
In a gas detection plant is it better to install a safety electrovalve normally open or normally closed?
The rule in force doesn't specify which is the best choice, so it is all up to the technician. The main difference between a normally closed valve with manual reset and a normally open one is that the first is "intrinsic safety" that is it can guarantee the gas leakage closing even without electricity and so even when the gas detection system is not working.
