Norway mine using Trolex sensors

London – The Svea Nord coal mine in Spitzbergen, Norway is using STX3241 and STX3261 toxic and flammable gas detectors and TX5920 vortex air flow sensors from Trolex to monitor CH4, CO and air flow.

The sensors have a high strength moulded housing sealed against dust and moisture to IP65 standard and EMC protection, making the systems resilient in the extreme, arduous conditions in the mine.

All the sensors have ATEX M1 approval, a legal requirement which identifies equipment that continues to operate when a potentially explosive atmosphere is present.

Tor-Arne Iversen, electrical engineer at mine operator Store Norske, commented: “Trolex gas sensing systems have been used in the mine since it opened in 2000 and are also used in JOY Machinery and in Sandvik Machinery. [This] is the only gas sensing equipment that we use to have ATEX M1 approval.”
