摘要
首先分析了扩散硅压力传感器灵敏度温漂的影响,然后以恒压激励方式的典型补偿电路为例,通过推导,提出一种在桥路中串入电阻的补偿方法。经测试数据的比对,证明该补偿方法切实可行,提高了传感器的性能。
The effects of temperature on the sensitivity of diffused silicon pressure transducer are analyzed. With the example of typical compensation circuit using constant voltage supply, a compensation method of connecting resistance in the bridge is stated. The intercomparison of the test data shows that the compensation method is feasible and the performance of the transducer is improved.
