Notes concerning certification:
1) The use of ATEX certified transducers is not allowed for different hazardous conditions or for those
exceeding the data specified on the nameplate affixed to the transducer.
2) The transducer does not require maintenance. Any work regarding performance checks or repair
should only be carried out in a laboratory duly authorized by CEMB SpA.
Notes for the identification :
The TRANSDUCER is manufactured in various versions in order to be correctly used according to :
1) the dangerous Zones where they will be used (zone 0 and 1)
2) the operating temperature (ambient t. and maximum t.)
3) the ambient operating characteristics (suitable or less suitable atmospheres for
the following materials : STAINLESS STEEL, ALUMINIUM, PLASTIC)
These characteristics must match in order to meet ALL the plant requirements. The CEMB codes with
which the main versions are identified and which meet requirements as per points 1 to 3 are as follows:
