2. Types of Temperature Sensors

Temperature Probes

Temperature probes, also known as temperature sensors, are devices that measure temperature and convert it into a readable form for various applications. They are essential in maintaining optimal conditions and ensuring safety across different fields.

Thermistor sensor s (NTC sensor and PTC sensor )

Thermistor sensors are temperature-sensitive resistors. They come in two types: Negative Temperature Coefficient (NTC sensors) and Positive Temperature Coefficient (PTC sensor). NTC thermistors decrease in resistance as temperature increases, making them ideal for precise temperature measurements in a wide range of applications, including household appliances and automotive systems. PTC thermistors, on the other hand, increase in resistance with temperature, often used as overcurrent protection devices.

Resistance Temperature Detectors (RTDs)

RTDs, such as the PT100 temperature sensor, measure temperature by correlating the resistance of the RTD element with temperature. They offer high accuracy and stability over a wide temperature range, making them suitable for industrial applications.
