Explosion-proof thermistor WZPK-240Product Overview:
Explosion-proof thermal resistor WZPK-240Employing the explosion-proof principle through gap quenching, we design components such as junction boxes with sufficient strength. All parts that could generate sparks, arcs, and dangerous temperatures due to explosion-proof heat resistors are sealed within the junction box cavity. In the event of an explosion within the cavity, the fire can be quenched and cooled through the gap between the mating surfaces, preventing the flame and temperature from spreading outside the cavity, thereby enabling temperature measurement.Explosion-proof thermal resistor WZPK-240Explosion-proof thermistors, through a specially structured terminal box, contain the explosive mixture within their casing. The interruption repair of the resistance element due to sparks or arcs inevitably alters the length of the resistance wire, affecting the resistance value. It is advisable to replace the resistor with a new one. If welding is used for repair, it must be tested and verified as合格 before use.

Explosion-proof thermistor WZPK-240Product Features:
1. A thermoresistor temperature measurement system typically consists of thermoresistors, connecting wires, and display instruments.
2. The graduation numbers of the thermoresistor and the display instrument must be consistent.
To eliminate the impact of the resistance change in the connecting wires, the three-wire system must be used.
4. Compact size, no air gaps internally, low thermal inertia, and minimal measurement lag.
5. Excellent mechanical properties, vibration-resistant, shockproof.
6. Bendable for easy installation
7. Long service life
