Working Principle of Temperature Sensor and Its Application

Thermocouples, Resistance Temperature Detectors (RTDs), Thermistors, Infrared, and Semiconductor Sensors. What is a Temperature Sensor? Usually, a temperature sensor is a thermocouple or a resistance temperature detector (RTD) that gathers the temperature from a specific source and alters the collected information into an understandable type for an apparatus or an observer. Temperature sensors are used…

Different Types of Temperature Sensors and Its Applications

Contact Type Temperature Sensor The contact type temperature sensor is in physical contact with the substance or object. These sensors are used to measure the temperature of solids, liquids or gases. Non-contact Type Temperature Sensor Non-contact type temperature sensors are used to detect temperature by interrupting a part of the emitted IR energy of the…

All About Temperature Sensors: Thermistors, Thermocouples, and RTDs

Learn all about temperature sensors and each of their advantages and disadvantages. Temperature Sensors   Temperature sensors are among the most commonly used sensors. All types of equipment use temperature sensors, ranging from computers, cars, kitchen appliances, air conditioners, and (of course) home thermostats. The five most common types of temperature sensors include: Thermistor Thermocouple RTDs…

Four Main Contact Temperature-Sensing Devices

There are four main contact temperature-sensing devices available, divided in three families: thermocouples (self-generating sensors), resistance temperature detectors and thermistors (resistive sensors), and temperature-transducing ICs (PN or Semiconductive). These sensors translate the temperature into a reference voltage, resistance or current, which is then measured and processed and a numerical temperature value is computed. Types of…
