Paper Abstract

A digital temperature testing system has been developed using a programmable chip for a ZY cutting-type quartz tuning fork temperature sensor. The system consists of hardware and software functionalities and it is implemented on an Altera Cyclone II EP2C35 Field Programmable Gate Array including a NIOS core processor. To satisfy the real time processing constraints on the one hand, and parameterization on the other hand, part of the algorithm are implemented in hardware and others are implemented in software. Experimental results indicate that the testing system can be used to measure the temperature with an accuracy of 0.01 degree C, and the effective resolution is better than 0.003 degree C in the range of - 20 degree C to 140 degree C.
