Abstract
In order to achieve high precision of calorific value measurement,the design of ultrasonic heat measurement system is based on TDC-GP2.The system uses platinum resistance temperature sensor PT1000 and ultrasonic transducer as sensitive units,TDC-GP2 as testing unit,and the combination of FPGA and PC to realize the acquisition,processing and transmission of data.Through the test,the maximum measurement error is less than 3%,the maximum error of temperature measurement is less than 0.5 ℃,Calorific value measurement error is better than 0.3%.关键词
