Similar to pressure sensors, many industrial plants also require temperature sensors to gauge temperature changes. Unlike simple thermostatic devices, temperature sensors are highly sensitive devices which can easily work in control plants. These devices are designed to measure the heat or cold within a system and detect changes that occur due to extreme temperatures.
Temperature sensors have a dial or display where measurements are displayed. This temperature-related information allows the operators to run the plant smoothly. If you are planning to buy temperature sensors then you must know that they are available in two different types.
Contact temperature sensors – These sensors must be placed near the object or unit. This is because they require physical contact with the application to sense the temperature levels. Contact temperature sensors are used to monitor the temperature of different liquids, gases and solids.
Non-contact temperature sensors – These types of sensors detect the radiant energy which is transmitted. Non-contact sensors can be used with various materials which emit radiant energy. These two temperature sensors are further divided into three different groups, electronic, resistive and electro-mechanical.
