INTRINSICALLY-SAFE Exi TRANSMITTERS ACCORDING
TO CERTIFICATE JSHP 22 ATEX 0051X
8.2.
Standards used for assessment
The transmitters are manufactured in compliance with the following standards:
EN IEC 60079-0:2018; (IEC 60079-0:2017 ed. 7.0),
EN 60079-11:2012; (IEC 60079-11:2011 ed. 6.0.).

Transmitter
explosion-proofing
designations
according
to
certificate JSHP 22 ATEX 0051X
The following ATEX markings apply only to intrinsically safe transmitters:
ATEX:
II 1/2G Ex ia
IIC T5/T4/T3 Ga/Gb
II 1D Ex ia IIIC T100
ºC/T135ºC/ T155ºC Da
JSHP 22 ATEX 0051X
As standard, the transmitters are manufactured for explosive gas atmospheres.
A customer can also order a transmitter for explosive dust atmospheres.
