Hazardous areas (explosive) are usually defined by the type of gas present, the concentration of the gas and also the ignition temperature of the gas. These areas are often designated as “Ex” areas, so in these areas it is very important to install the correct specification of equipment. “Ex” areas are generally split into several categories. Our company has technologies especially for “Ex” zone 2 and “Ex” zone 1.
“Ex” zone 1 – gas is likely to be present in normal process conditions, area usually categorised as “Ex”, meaning explosion proof equipment is required (More than 10 hours per year but less than 1000 hours per year).
“Ex” zone 2 – gas not likely to be present in normal process conditions, however if gas is detected it will only be brief periods of time, equipment in these areas are generally hermetically sealed and non sparking (Less than 10 hours per year).
Our hazardous area gas detectors have IECEX and ATEX compliance .
Hazardous areas may contain flammable liquids, solvents and toxic chemicals. All of our systems can be connected to other systems to allow continuous monitoring and allow historical logging. We as standard have multiple analog and digital outputs that can activate both visual and audible alarms i.e. beacons/sounders. We also have IECEX certification so you can be confident that we conform with all necessary legislation and regulations, so our sensors can be installed in Hazardous areas.
Our fixed and portable gas sensors are accurate to 0.1 % of the LEL / VOL scale, so you can be sure of reliability and timely indication of the gas presence reaching alarm limits. At which point you can relay the alarm condition via sounder / beacon, your internal system or most other audio / visual warning equipment.
