摘要
铂电阻温度传感器在航空工业中具有广泛的应用,本文系统地分析了各类引线方式的铂电阻传感器的采集电路,利用恒流源和不平衡电桥构成对三线制电阻的测量系统,该测量系统对三线制铂电阻传感器的各类异常情况具有告警功能,具有显著的工程应用价值。
Platinum resistance transducer is widely used in the aircraft industry. This paper studies the measuring circuit of platinum resistance transducer that with all kinds of different lead. The System uses the constant current source and unbalanced bridge principle to build the three-wire resistance measuring system,it can give an alarm when the three-wire resistance transducer appear failure,and this characteristic has important value in engineering field.
