Explosion proof platinum resistors used in the chemical industry are a type of temperature sensor. It is widely used in industrial automation systems. Through temperature sensors, the temperature parameters of the controlled object can be converted into electrical signals, which are transmitted to display, record, and regulate instruments to detect, adjust, and control the system. In chemical plants and production sites, various flammable and explosive chemical gases and vapors are often present. Using ordinary platinum resistors is very unsafe and can easily cause environmental gas explosions. Therefore, in these situations, explosion-proof thermocouples must be used as temperature sensors. The explosion-proof platinum resistance products produced by our factory are suitable for use in places with explosive gas hazards within the temperature range of d II BT4~d II CT6 The explosion-proof thermocouples produced by our factory use imported components as temperature sensing elements, and their technical performance meets the technical requirements and division table of ZBY301-85 industrial platinum electric technology. At the same time, the product meets the general requirements for explosion-proof electrical equipment used in explosive environments GB3836.1-83 and GB3836.2-83 standards.
