Working principle of temperature cycle. Temperature measurement using a format change from an analog signal voltage level into. Digital signal in relation to the temperature sensor of the major formats are 3 Thermocouple temperature measuring device is the format used by the main changes to the voltage as temperature. Made from different types of metal conductors that connect the 2 ends together at one end, called the "temperature". Part one end open release called "reference point". If the temperature measured at the point and a point of reference in different temperatures, it will bring the currents in the circuit. Resistance Temperature Detector (RTD), Thermocouple is a sensor that uses temperature, change the value of the metal, which resistor value of resistance will be increased by the value of the temperature resistance of the metal. Called "a positive temperature coefficient changes" adopted in measuring temperatures in the range-270 to 850° C. material applied to a metal with low specific resistance, such as nickel, tungsten and Platinum Thermistor. Is a device that can change the type of resistance, resistance value when heated. Resistance values will not change linearly with the temperature is divided into two styles, is Positive (PTC) Temperature type Comitial usually has a low resistance value when receive heat will make higher resistance values are respectively the temperature. Applied to check the level of heat or heat up to regulate the voltage to the coil, rinse cycle, such as the magnetic field of color television receivers (Degaussing coil) Negative Temperature (NTC) as the type Comitial usually have a high resistance to heat. Resistance value will be lower. Active monitoring to control the level of heat, such as in a good amplifier circuit is used to detect the heat caused by the work, and then to reduce the feedback cycle. To the main unit will not result in excessive heat.
