Introduction

B57411V2331H62 is a temperature sensor based on NTC thermistors. The B57411V2331H62 is a device that responds to changes in temperature by changing its electrical resistance. It has a very wide operating temperature range of -40°C up to +150°C and is small in size and has a low cost.

Application Field

B57411V2331H62 is used in a huge range of applications for both commercial and industrial purposes. Common applications where B57411V2331H62 is used would be temperature controlling and monitoring in refrigeration equipment, air conditioners, automotive engines, water heaters, and many other types of thermal measuring systems. B57411V2331H62 is also used in safety systems for temperature regulation and thermal protection, as well as in medical applications.

Working Principle

In order to measure temperature, the B57411V2331H62 relies on the Seebeck Effect, also known as the thermoelectric effect. The Seebeck Effect states that a voltage can be generated from two dissimilar conductors when a temperature difference is applied across them. The B57411V2331H62 exploits this principle by using an NTC thermistor as one of the conductors, and a second conductor as a reference. The B57411V2331H62 measures the temperature difference between the two conductors.The internal electrical resistance of the NTC thermistor increases as the temperature decreases. When a current is applied to the B57411V2331H62, the resistance of the NTC thermistor modifies the voltage across both conductors. This change in voltage is then measured by the B57411V2331H62 and the resistance is converted into a temperature reading.
