Ex i Temperature sensors

Ex i, intrinsically safe, for zones 0, 1, 2, 20, 21 or 22

  • The sensor is a standard-type RTD or TC temperature sensor (no ATEX/IECEx requirements)
  • The connection hood is a standard-type, IP 65-protected hood, with a protective earth connection screw (no ATEX/IECEx requirements)
  • The whole circuit must be designed as an intrinsically safe Ex i circuit (cable length, ATEX/IECEx transmitters, ATEX/IECEx barriers).

Investigated applicability

  • EPIC® SENSORS standard RTD types have been investigated for applying in Ex i circuits by an authorized body Eurofins Expert Services Oy and the resulting statement can be downloaded here: STATEMENT VTT-S-08226-13 (pdf).
  • Our RTD and TC sensor's standard types are also approved for intrinsically safe circuits in Euro Asian Customs Union area (EAC; Russian Federation, Belarus and Kazakhstan), according to the certificate EAC-Ex (pending).


Lapp Automaatio now offers the possibility to install the IoTKey® wireless measurement and remote monitoring system in hazardous industrial environments.
