Introduction

Temperature sensors are devices that measure the temperature of a given environment or system. Among these sensors, the NTC thermistors behave differently when exposed to changes in temperature. They present a large resistance drop when temperatures rise, which allows the sensors to measure the temperature accurately. The 128-202VLD-S02 is a NTC thermistor produced by the Vishay company, and is used extensively within various industries for temperature sensing applications.

Application Field and Working Principle of 128-202VLD-Q02

The 128-202VLD-Q02 is an ideal temperature sensor due to its excellent accuracy and stability, while also being easy to install and inexpensive.
