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…

Temperature Sensors Uses

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…

Sensors

Introduction Pressure Sensors – Motorola A sensor is a device that produces a measurable response to a change in a physical condition, such as temperature or thermal conductivity, or to a change in chemical concentration. Sensors are particularly useful for making in-situ measurements such as in industrial process control. Sensors are an important part to…

Thermocouple

thermal junction, thermoelectric thermometer, or thermel, a temperature-measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature. A measuring instrument is connected in the circuit. The temperature difference causes the development of an electromotive force (known as the Seebeck effect)…

Thermocouples

What’s the connection between electricity and heat? Have you noticed that when we talk about conduction in science we can be referring to two things? Sometimes we mean heat and sometimes we mean electricity. A metal like iron or gold conducts both heat and electricity really well; a material like a plastic doesn’t conduct either of them very well at all. There is a connection between…
