Special conditions for use (X conditions)
- Thermometers (mechanics) contain no internal heat source,
and, when correctly installed and operated, cause no increase in
temperature. The temperature class and maximum surface
temperature are determined by the instrument design and the
ignition temperature of the surrounding explosive gas and/or
dust environment (atmosphere) according to the manufacturer's
technical documentation;
- Thermometers with model 831 electrical contacts must be
connected to intrinsically safe circuits of duly certified products
(safety barriers);
- Installation, operation, and maintenance of instruments are
carried out in accordance with the manufacturer’s instructions
according to its technical documentation;m the process which
exceeds the ignition temperature of the explosive gas and/or
- Heat return flow from the process which exceeds the ignition
temperature of the explosive gas and/or dust environment
(atmosphere) surrounding the instrument case is not permitted
and must be prevented through appropriate thermal insulation.
