Caracterización de sensores de temperatura termopar, Termistor y RTD

Abstract

This article shows the implementation of the 3 types of sensors of temperature, which are pt100 of 3 threads (RTD), termocupla type J (Thermocouple) and a thermistor of 10KΩ NTC (Thermistor). You have in order to be able to implement these 3 types of sensors using like mainframe the PSoC 5lp, which helps us as to the circuits of connection, since you possess an ADC of 20 bits and a specific block out of every sensor, to obtain a full measure and hurry. Besides the above mentioned also himself I implement a control block, which helps us to the sensors to vary the temperature of the liquid in which they are going to be present, and finally a graphic interface comes true, in which observe him the temperature out of every sensor and some graphs like curves of hysteresis, and linearity.
