Temperature is the most frequently measured parameter in modern production facilities.
The definition of temperature is the energy level of matter which can be shown by some change in that matter. You will find a wide variety of temperature measuring solutions. They all measure temperature by sensing change in a physical property or characteristic.
The basic types of temperature measuring sensors are thermocouples, resistive temperature devices (RTDs, thermistors), bimetallic devices, infrared radiators, liquid expansion devices, molecular change-of-state and silicon diodes.
Temperature monitoring products are designed to cope with tough applications in processing and manufacturing industries.
