Only equipment and protective systems with the corresponding certification and markings are to be put into operation in potentially explosive areas! In response to the market requirements tecsis has developed force transducer with a thin-film measuring cell and integrated amplifier, which will be ATEX and international IECEx approved.

What is a potentially explosive atmosphere?
A potentially explosive atmosphere is a mixture of air and combustible gases, vapors, mists or dust under atmospheric conditions, in which after ignition has occurred, combustionspreads to the entire unburned mixture. An explosion-risk area is an area in which the atmosphere may become explosive because of local and operational conditions.

Why ATEX-approved force transducers required?
Since primary explosion protection is
not always possible, there is a need for suitably designed electrical and non-electrical equipment, such as force transducers, which can be used as part
of the secondary explosion protection. On account of stricter regulations and requirements, we expect demand to increase in the future for ATEX-approved force transducers.

Which ATEX approvals are needed?
The tecsis force transducers with a thin-film measuring cell and integrated amplifier now have approval accordingto directive 94/9/EC in equipment group II (non-mining products), category 2G for zones 1 and 2 (gases). If necessary, other zones are also possible, please ask.

Who decides about the zone classification?
The assessment of the risk for an explosion and zonal classification is to be carried out by the plant operator.
The guidelines for avoiding dangers
from potentially explosive atmospheres (Ex Guidelines) published by the chemical industry serve as the basis
for decision-making.

What advantages are offered by tecsis ATEX-approved force transducers?

• All of the other known advantages of our very competitive thin-film force transducers.
• Amplified output signal, due to the integrated amplifier.
• No expensive zener barrier assemblies are required to deploy in ATEX zones.
• All thin-film force transducers are “Made in Germany”.
