Ex e / Ex t Temperature sensors

Ex e - increased safety, for gas zones 1 or 2
Ex tb - dust-protected enclosure, for dust areas.

The Ex e type EPIC® SENSORS temperature sensors are Ex II 2G / 2D approved, and they are applicable for Ex zones 1, 2, 21 and 22. 

  • The sensor is an ATEX and/or IECEx or EAC or KCs certified, Ex e-type, Pt100 or TC sensor, which can also be used for dust areas, thanks to its dust-protected Ex t enclosure.
  • The measuring circuit can be cabled to a safe area and to a standard device (no ATEX/IECEx requirements).
  • The product certificates give more detailed specifications, e.g. the ambient temperatures allowed for the approved sensors.  
  • The currently approved sensor range and product certificates are listed below.

ATEX

  • Lapp Automaatio Oy has been granted an ATEX Quality Assurance Notification EESF 18 ATEX Q 006, as required under EU directive 2014/34/EU. The notification, issued by Eurofins Expert Services Oy*, gives the right to manufacture temperature sensors with the protection concepts Ex d, Ex e, Ex i, Ex m and Ex t, for use in explosive atmospheres. 
  • When ATEX certified sensor types are needed, we will manufacture e.g. Ex II 2G Ex e IIC T6...T3 Gb, Ex II 2D tb IIIC T60°C...T200°C Db approved sensors. Please find copies of the product certificates below.
  • We can manufacture and apply for authorization also for different kind of Ex e-designs, which are to be individually agreed. Please contact our Ex experts.

IECEx

  • Lapp Automaatio Oy's sensor manufacturing operations have been assessed in an IECEx Quality Assessment Report FI/EESF/QAR18.0004 (link to the IEC database), as required by the EN ISO/IEC 80079-34 standard. The auditing organization was Eurofins Expert Services Oy*. The report gives the right to manufacture Ex e, Ex t, Ex d, Ex m and Ex i type temperature sensors for use in explosive atmospheres and to apply for IECEx approval for them. 
  • When IECEx product certified sensor types are needed, we will apply for authorization for existing sensor types or produce new ones. IECEx product certificates are applied for on request.

*NOTE! Name since 1.4.2022 is: Eurofins Electric & Electronics Finland Oy 

EAC

  • Selected Ex sensors are also approved for use in Euro Asian Customs Union area (EAC; Russian Federation, Belarus and Kazakhstan), according to the EAC certificate (please see Downloads section). 

KCs

  • Lapp Automaatio Oy's sensor manufacturing operations have also been audited by KTL Korea Testing Laboratory.
  • Selected Ex sensor types; WT-BAJONETTI...EX (W-Bayo...Ex), WT-KAAPELI...EX (W-Cable...Ex), T-M-303...Ex and W-M-303...Ex, are approved for use in Korea, according to applicable KCs certificates and audit conformity notification (please find copies in Downloads section).

Short code key comparison - old vs. new

Part of the product certificates are still carrying old code types, which were valid, when the certification took place. Since the certificates have no due time, the types will remain.

Below please find a comparison between some old and new code key markings.
