Temperature sensors are used in a wide range of industrial applications. They can be used for temperature control, for example in the heating and cooling systems of buildings or for processing plants.
Temperature sensors are also used in many other industries such as food processing, chemical plants, power stations and many more.
The use of temperatursensorer is becoming increasingly important because of the increasing need to improve efficiency and reduce energy consumption.
In order to meet these requirements, it is necessary to have reliable, accurate and cost-effective temperature measurement devices which can be implemented quickly and easily into existing processes or new installations.
Types of industrial temperature sensors:
Thermocouple: A thermocouple is a temperature sensor made up of two dissimilar metals that generate an electrical current when heated. The thermocouple’s magnitude depends on the amount of heat added to the metals. Thermocouples have lower accuracy, but can be used over a wider range of temperatures than RTDs (Resistance Temperature Detectors).
Thermistors: Thermistors are similar to resistors in that they have one fixed value and their resistance changes with temperature. The amount of change, however, is not linear like with a thermistor. They also don’t require external power other than the heat source they’re measuring. Thermistors can be used across a wide range of temperatures where RTDs would fail at low or high temperatures.
