Differentiate between Industrial and Temperature Sensors.

Temperature sensors have a vital role in many households and industrial machines. All home appliances used temperature sensors for their proper working. For example refrigerator turns off automatically when it reaches to certain value of lower temperature. In the same way it turns on when temperature became high. Temperature sensors are used in cooking food and by air conditioning systems. Smart home technologies also used temperature sensors to perform their task. For example smart home systems use temperature sensors to maintain the temperature of water in tanks. The temperature sensors which are used in domestic appliances or domestic purposes have very small and limited range. Beyond a certain amount of temperature they cannot measure temperature because in household activities a normal temperature is considered. These sensors are the sensors which need a direct contact with the environment. These sensors are simple and mostly made up of silicon tube. On the other hand a wide range of temperature sensors are used in in the industry. These sensors are used to calculate a very large value of temperature which can be as high as 500 degree centigrade or as low as -200 degree centigrade.
Temperature calculating factors were introduced by Greek philosophers about two thousand years ago. In the 18th century these scales were used to calculate the amount of heat using thermometers. In the past there were no standards to calculate the amount of heat in a certain unit. That is why it was very difficult to compare different temperature values. These days thermodynamic temperature scale is present. All the temperature calculation is done by using this scale. Thermodynamic temperature scale depends upon the third law of thermodynamics which states that theoretically there is a lowest temperature which is considered as one zero or absolute zero and all the values of temperature are measured with it. All the latest temperature sensors are using these thermodynamic temperature standards. These days there are three scales are present for the measurement of temperature. These scales are Celsius scale, Kelvin scale and Fahrenheit scale. All the latest temperature sensors which are either use in home or in the industry, use these scales for measuring the temperature.
