A Review of the Main Temperature Sensors for Control System and Assignment

A Review of the Main Temperature Sensors for Control System and Summary of the characteristic Sensors for Measurement of Rainfall - Assignment ExampleThermocouples be widely used because they are reliable, simple to use, and allow a relatively lower price compared to other sensors (Seaton & Leach, 2005). Thermocouples are self-powered, thus eliminating the use of a key out or an external power supply to the sensors. They are durable when they are chosen appropriately for a designed application. Ibrahim and Coupland confirm that the thermocouple sensors are used in applications that handle very high temperatures much(prenominal) as incinerators. A thermocouple is a temperature transducer, which operates on a principle that unlike conductive materials is clear of generating current when they are joined (Setback effect) (Jianwei Shen & Shen, 2009). Such devices are made by joining two wires that are made of alloys (different metals) joined at one end, and then generating a volta ge of EAB when heated. Jikwang, Jonsung, and Younghwa (2009) emphasize that the produced voltage is comparative to the difference between the legal communityd joint temperatures and the reference point, which is determined experimentally and it depends on the type of materials that are used. A temperature monitoring system when using a thermocouple includes connectors, thermocouple, isothermal block, extension wires, and a transmitter also known as a voltmeter.This schematic (figure 6) is for type J iron (Fe) Constantin Cu-Ni thermocouple. Nieuwenhove and Vermeeren (2004) describe that when the thermocouple junction is cooled or heated, a digital voltmeter or potentiometer can be used to measure the resulting voltage.
