Virtual Tool Used for Testing Temperature Sensors

Among the most essential aspects that must be known in using all sensors are their transfer characteristic and response time. Their identification is made in relation to the static and dynamic modes of use of the sensors. In this paper is proposed an application written in LabVIEW, called a virtual instrument, which allows the construction of the transfer characteristic and the identification of the response time for temperature sensors, both in graphical forms. The presented application is customized for the NTC thermistor but can be equally applied to the resistance temperature detector (RTD) or thermocouple. NI ELVIS is used in its realization, which is an engineering laboratory equipment that combines virtual instrumentation and embedded technology.
