Researching about a Instrument to Measure Nonmetal Electrothermic Element's Parameters on the Spot

介绍一种采用 80 31单片机构成的高精度、智能型电热元件参数在线测量仪。该测量仪采用简单的欧姆定律测量电热元件电阻 ,同时可进行电压、电流的测量 ,测量过程由单片机控制 ,测量结果可以进行在线显示 ,并可通过 RS- 4 85口实现计算机通信 。

A new high precision intelligent instrument composed of single chip 8031 to measure the electrothermic parameters was introduced.This instrument applied simple Ohm's law to measure the resistance of electrothermic element,and the voltage and the electric current can be measured at the same time.The process of measurement was controlled by single chip,and the outcome can be displayed on the spot.Moreover,the electric parameters can be transmitted long distance by RS-485,and it can be easy to be composed of FFD system.
