Using Your Thermocouple
Temperature monitoring is central to the majority of data acquisition systems, be it to save energy costs, increase safety, reduce testing time...whatever your reasons, you will need a device to measure the temperature - a temperature sensor. Thermocouples, resistance temperature devices (RTDs), thermistors and infrared thermometers are all types of temperature sensor. Which you choose depends on factors like your expected maximum and minimum temperatures, the accuracy you need and your environmental conditions. The most popular sensors are thermocouples and RTDs. We've concentrating on potential problems when using them in computerised temperature measurement.
