ATEX Certified sensors

Since august 2019, the SEC Signature DIR sensors have the ATEX certification (mandatory European standard for machines and installations with explosion risks) thanks to RSD company. Indeed, we managed all the process to get the ATEX certification, with the support of the manufacturer, Sensor Electronics Corporation.

Now these sensors are ATEX certified by the notified body LOM, and fulfill the ATEX directive 2014/34/UE. They can so be used in EtO sterilizers and EtO sterilization facilities given that they are 100% qualified for use in ATEX zone 2, in any European countries.

A great news for the European companies that sterilize their products with the ethylene oxide sterilization process.
