| Abstract: | A pressure temperature multifunction sensor with RS232 compute communication interface is introduced in this paper. A pressure temperature multifunction sensor, a R/V convertor, a preamplifier, a A/D convertor and programmed RS232 interface cell were integrated. Collecting and processing program for sensor output data were designed, by which the error of the sensor was compensated. Result shows that the precision of the sensor was improved, and the null temperature drift was reduced from 4.4%/℃ to 0.2%/℃。 |
