indicator series PUE C/31H/EX and scales constructed on its
basis cab be utilized in expolsive zones 1 and 2 of mixtures
of gases, vapours and fogs with air, which are included in exposive
group II and temperature classes T1, T2, T3, T4.
Safety of measuring indicator and scales using PUE C31H/EX is guaranteed by such means as:
- power supply of the indicator from power adapter ZRi02 II (2) G [EEx ib] IIC 06ATEX251 manufactured by RADWAG, and situated outside expolsive zone or another power adapter with parameters adequate for spark secured circuit.
- spark secured casing of measuring indicator series PUE C31/H/EX, being in conformity with norms: PN-EN 50014 and PN-EN 50020 and confirmed by a certificate KDB 06ATEX250
- application of transducers with exposive safety certificates
- manufacturing of the indicator according to requirements of a norm PN-EN 13463-1 on non-electrical elements of a scale
- user obligation to obey safety precautions as indicated in the user manual of the measuring indicator
CAUTION:
scale equipped with a measuring indiocator series PUE C/31H/EX are fed from power adapter ZRi02 II (2) G [EEx ib] IIC 06ATEX251 manufactured by RADWAG, situated outside the explosive zone or another power adapter with parameters adequate for spark secured circuit.
