磁芯采用高频脉冲电流励磁,信号处理电路由峰值检波、低通滤波及差动电路构成。
The toroidal core was excited by sharp pulse current. The sensor circuit is composed of peak value detector, Butterworth low-pass filter and differential amplifier.
慢速响应的滤波器能够对数据的峰值点起平滑的作用,从而可能会丢失重要的温度信息。
A slow responding filter will smooth the peaks of the data, which could allow vital temperature information to be lost.
特别注意不要使滤波器的响应时间在热曲线的峰值点引起误差。
Take care that the response time of the filter doesn't cause errors in the peaks of the heat curve.
