BT93420 Temperature Indicator Transmitter
Introduction of temperature indicator trasmitter:
thermistor temperature sensor is a temperature measurement device based on the principle of thermistor resistance. Its working principle is to measure the temperature of the environment or object by utilizing the characteristic of the resistance of the thermistor material changing with temperature.
The thermistor temperature sensor usually consists of a thermistor element, connecting wires, and a housing. The thermistor element is the core part of the sensor, which is made of a special material such as copper oxide or nickel oxide. These materials have different resistance values at different temperatures, and the resistance value changes correspondingly as the temperature increases or decreases.
When the thermistor temperature sensor is connected to the circuit, the temperature of the environment or object can be calculated by measuring the change in resistance value. The output of the sensor can be an analog signal or a digital signal, depending on the specific sensor design.
Thermistor temperature sensors have the characteristics of fast response, high precision, and good stability. They are widely used in various fields, including home appliances, automotive industry, medical equipment, industrial control, etc. By using different types of thermistor materials and design parameters, different temperature measurement needs in different application scenarios can be met.
