There are many explanation regarding thermocouples, current, integrated circuit, temperature characteristics, accuracy, self heating, measurement, current excitation, order, signal, thermocouple, technology, and protection are presented inside the application note. This application note tells the reader discussion around design, temperature measurement, temperature, wire resistance, error contribution, range, application, linearization, rtd, sensor, package, and sensing technologies.
Inside the application note the reader can find explanation related to linearity, circuit, thermal response, prtd, ptc, voltage, error, wire, calibration, effect, temperature sensing, temperature response, and code protection. These are grabbed from the application note:
Of the temperature sensors discussed in this application note, the RTD is the most linear with only two coefﬁcients in the linearization equation, 2 R t = R 0 ( 1 + At + Bt ) for temperatures 0 ˚C to 859 ˚C 2 3 R t = R 0 ( 1 + At + Bt ) + C ( t – 100t ) for temperatures -200˚C to 0˚C where Rt is the resistance of the RTD at measurement temperature, t is the temperature being measured, R0 is the magnitude of the RTD at 0˚C, A, B and C are calibration coefﬁcients derived from experimentation.
Even more, this application note presents info about microchip technology, temperature sensors, cold junction, signal conditioning, characteristics, thermistor resistance, rtds, thermocouple types, thermistor, response, error analysis, and junction compensation.
