Main idea: TOPOS adopts aging glass bead thermistor and high-pressure PVDF tube to keep the sensor's stability.
Industry: The thermal protection of green-car charging pile
Challenge: Due to the long-time work and harsh outdoor environment, so there is a challenge that how to keep the temperature sensor's stability. IP67 waterproof, pressure-resistance 5000VDC
Solution: TOPOS adopt the aging glass bead thermistor, it is more stable, and the glass sealed the chips, cut off the air, water, make sure the thermistor after 10,000 hours of work, the resistance deviation is less than or equal to 3%. Uses hot melt die-casting of PVDF heat shrinkable tubing with high-temperature adhesive, response speed, water-resistance and pressure resistance are greatly improved to adapt to long-term work and outdoor harsh environments.
Impact: After TOPOS adopts new technology, the thermistor sensor in car charging pile will not be affected by the surge current and harsh outdoor environment.
