Silicon Piezoresistive Sensor's Intelligent Temperature Compensation
摘要
Abstract
For silicon piezoresistive sensor's temperature drift problem,an intelligent temperature compensation system was designed by adopting MAX 1452 signal conditioning chip. The system includes hardware and software and it can compensate 8 sensors once a time. The system performance tests of pre-compensation and post-compensation are made under different temperature and different pressure. The results show that the designed system is reliable,sensor's error from temperature is reduced obviously after compensation and the precision is achieved within 0.2%.关键词
