THERMISTOR SENSOR

Solution

Proposal of optimal
temperature sensor

Challenge

Hope to discuss the structure and shape of the sensor

  • Looking to measure the temperature accurately.
  • Do not know what thermistor should be used.
  • Do not know if the thermistor currently in use is the most optimal.
  • Please make a proposal that includes the mounting method and installation method.

Solution Overview

Effect

  • Before

    After the temperature cycle test, the sensor resin cracked. The stress simulation revealed that the stress was concentrated due to the mismatch of the resin materials.

  • After

    By changing the resin material, it is verified by simulation that the stress is relieved, and a highly reliable sensor design is achieved.
