An Innovative Approach to Addressing the Waterproofing Challenges of NTC Temperature Sensors

Abstract

Aiming at the waterproofness problem of NTC temperature sensor, a new method was proposed to coat NTC thermistor with double-layer Teflon heat shrinkable tube. Different sample groups were made of electric boiling experiments. The difference between the method and the conventional epoxy-resin-coated NTC thermistor was compared. The results show that the temperature sensor made by this method has excellent waterproof performance and meets the expectation.
