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…

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)…

Choosing a Temperature Sensor

Choosing Temperature Sensors

Temperature measurement, a vital part of most industrial operations, is typically accomplished by a temperature sensor–a thermocouple or a resistance temperature detector (RTD)–in contact with a solid surface or immersed in a fluid. Although these sensors have overlapping temperature ranges, each has certain application-dependent advantages. Here is some information to help when choosing temperature sensors.  …
