ATEX certification updated: temperature gauges

Badotherm has again updated the ATEX certification. Now, all Badotherm bi-metal and gas-filled thermometers can be ordered according the requirements of the ATEX Directive 94/9/EC.

Next to the temperature gauges, also the main industrial stainless steel pressure gauges are certified. These are the following types BDT18, BDT19, BDT20, BDT21 and BDT12 (diaphragm type gauge) and BDT13 (differential pressure gauge).

The ATEX Directive is named after the French "ATmosphere EXplosible" and is a so-called "New Approach" Imagedirective which provides the technical requirements to be applied to equipment intended for use in potentially explosive atmospheres. The directive covers a surprisingly large range of equipment, including apparatus used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where an explosive atmosphere may be present.

Broadly speaking, there are three pre-conditions for the directive to apply to the equipment. It must:

  • a) have its own source of ignition;
  • b) be intended for use in a potentially explosive atmosphere (air mixtures); and
  • c) be under normal atmospheric conditions.

The directive covers components essential for the safe use and safety devices directly contributing to the safe use of the equipment in scope. The latter devices may be outside the potentially explosive environment.Badotherm gauges that are ATEX approved have the required marking on the dial so that they can be easily recognized as being certified accordingly. Specific manuals for these ATEX gauges can be found on the Badotherm internet site. The ATEX registration is documented under decision number: SECEEx.ATEX.2005.024.
