  • Introduction
  • Specifications
Mine explosion-proof (intrinsically safe)-type platinum resistance is designed and manufactured for practical needs of coal mine production safety. Explosion-proof properties of the product are in line with the national standard (GB3836) and the related standard. Thermoelectric properties are in line with international IEC standards. The instrument case is made of stainless steel material. It imports foreign advanced manufacturing technology to product armored platinum resistance as the temperature components. It has accuracy temperature measurement, fast thermal response time,
Dust-proof, water-proof etc. features to satisfy the conditions requirement of mining coal underground. It is tested by the state inspection department. It is an ideal temperature sensor in explosive environment.
As the temperature sensor, it can be completed with display instrument and control system to measure the media temperature in the production.
