Abstract

Actually, quasidigital sensors are become very important in noisy environments. In order to learn how quasidigital sensor works, the target of this paper is to design a data acquisition system based on a computer and a PCI (NI Pci-6221) data acquisition board to acquire data from SMT160 quasidigital temperature sensor using the ELVIS platform and Labview as a language programming software. In addition the Universal Transducer Interface from Smartec will be evaluated as an analog to frequency converter for resistive and capacitive sensors. The objective of this present paper is to study and to realize a practical application that can be called a revolution in the sensor application because it doesn’t need any additional elements or any signal acquisition: UTI (Universal Transducer Interface).
