Overview

One Product Overview: WZP industrial explosion-proof thermistor is used as a sensor and display instrument for temperature measurement and control, to directly measure and control the temperature of gases, liquids, and vapors in the production process. Our company's chemical specific explosion-proof thermocouples and thermal resistors are designed and manufactured according to the national standards for explosion-proof electrical equipment used in explosive environments. Their thermal and electrical characteristics comply with international IEC standards and have been tested and approved by the National Instrumentation Explosion proof Safety Supervision Station. The structure, principle, and assembly method of explosion-proof thermocouples and thermal resistors are basically the same. The main difference is that the explosion-proof product junction box (housing) is designed with high-strength aluminum alloy die-casting, and has sufficient internal space, wall thickness, and mechanical strength. The thermal stability of the rubber sealing ring meets national explosion-proof standards. II Product features: Compression spring type temperature sensing element with good anti vibration performance; High measurement accuracy; No need to compensate for wires, saving costs; Imported thin film resistor components with reliable and stable performance. III The working principle of explosion-proof thermistor is to use 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 cavity. When an explosion occurs inside the cavity, it can be extinguished and cooled through the gap between the joint surfaces, so that the flame and temperature after the explosion cannot be transmitted outside the cavity, thus achieving explosion-proof. 4 Main technical parameters: Product execution standard IEC751JB/T18622-1997JB/T8623-1997JB/T5518-91 V The insulation resistance and thermal resistance at room temperature are tested at an ambient temperature of 1535C, relative humidity not exceeding 80%, and a test voltage of .....

One Product Overview

WZP industrial explosion-proof thermistor is used as a sensor and display instrument for temperature measurement and control, to directly measure and control the temperature of gases, liquids, and vapors in the production process. Our company's chemical specific explosion-proof thermocouples and thermal resistance products have explosion-proof performance in accordance with the national regulations“Explosion proof electrical equipment for explosive environments”Standard design and manufacturing, with thermoelectric characteristics that comply with international standardsIECStandard, and tested and qualified by the National Instrument Explosion proof Safety Supervision Station. Explosion proof thermocouple The structure, principle, and assembly method of thermal resistors are basically the same, with the main difference being that the explosion-proof product junction box (housing) is designed using high-strength aluminum alloy die-casting, and has sufficient internal space, wall thickness, and mechanical strength. The thermal stability of the rubber sealing ring meets national explosion-proof standards.

II productfeature
Pressure spring type temperature sensing element with good anti vibration performance;
High measurement accuracy;
No need to compensate for wires, saving costs;
Imported thin film resistor components with reliable and stable performance.

IIIworking principle
Explosion proof thermistor utilizes the principle of gap explosion-proof to design junction boxes and other components with sufficient strength. All components that can generate sparks, arcs, and dangerous temperatures are sealed inside the junction box cavity. When an explosion occurs inside the cavity, 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 cavity, thus achieving explosion-proof.
