The transducer is a component that works to convert physical parameters into electrical signals that can be accepted by the signal processing system. Several physical parameters are often known to be converted into electrical signals, among others: pressure, temperature, acceleration, shifting, speed, and so on. One of transducer type is thermocouple transducer.
Thermocouple transducer is the most widely used to measure temperature based on the conversion of temperature into electrical signal. Thermocouple transducer works based on the powerhouse at point of metal axis that is not same. This voltage is proportional to temperature of connection.
