Explosion proof platinum resistance products are suitable forWithin the temperature range of dIIBT4 to dIICT6, the explosion-proof thermistor uses imported components as temperature sensing elements, and its technical performance meets the technical requirements and division table of JB/T8622-1997 Industrial Platinum Electrical Technology. At the same time, the product meets the general requirements for explosion-proof electrical equipment used in explosive environments GB33836.1-2000 and GB3825.2-2000 standards. The National Instrument Explosion proof Supervision and Inspection Station conducts specialized review and approval of the product's drawings, technical documents, and prototypes, and issues an explosion-proof certificate of conformity.

Explosion-proof rating

The explosion-proof rating of explosion-proof thermal resistors is divided into three levels: A, B, and C, based on their suitability for explosive gas mixtures with the largest gap.

Temperature group

The temperature group of the explosion-proof thermistor is divided into six groups based on the highest surface temperature T1 to T6 of its exposed part.
