Explosion proof thermocouple temperature transmitter

WRKB--248Explosion proof thermocouple temperature transmitterDetailed introduction:WRKB--248Explosion proof thermocouple temperature transmitterIt is a temperature sensor widely used in chemical industry automation systems. The WREK-248 explosion-proof thermocouple can convert the temperature parameters of the controlled object into electrical signals and transmit them to display instruments, recorders, and regulators to detect, adjust, and control the system. In chemical plants, various flammable and explosive chemical gases are often present on the production site. Using ordinary thermocouples is very unsafe and can easily cause environmental gas explosions. Therefore, WREK-248 explosion-proof thermocouple must be used as a temperature measuring instrument in these occasions. Our company's explosion-proof thermocouple products are suitable for use in places with explosive gas hazards within the EXd Ⅱ CT6 temperature group range. Working principle: If a closed circuit is composed of two homogeneous conductors (thermoelectric electrodes) with different compositions, when there is a temperature gradient at both ends, current flows through the circuit, and there is a thermoelectric potential between the two ends (as shown in the figure below)WRKB--248Explosion proof thermocouple temperature transmitter防爆原理:WRKB--248Explosion proof thermocouple temperature transmitterBy utilizing the principle of gap explosion-proof, design junction boxes and other components with sufficient strength, and seal all parts that can generate sparks, arcs, and dangerous temperatures inside the junction box. When an explosion occurs inside the chamber, it can be extinguished and cooled through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the chamber.WRKB--248Explosion proof thermocouple temperature transmitterFeatures: Designed according to the explosion-proof regulations GB3836 that comply with IEC standards;WRKB--248Explosion proof thermocouple temperature transmitterAdopting a two chamber explosion-proof structure, it is easy to replace temperature measuring elements and safe and reliable to useWRKB--248Explosion proof thermocouple temperature transmitterExplosion proof mark EXd Ⅱ CT6, suitable for temperature measurement in environments with Class IIC or below, ignition temperature T6 or above, and containing explosive gases.
