我们设计的温度传感器,有较高的线性、灵敏度及稳定度。由于采用了较先进的集成电路和性能稳定的单晶热敏电阻,可代替传统的铂电阻体和温度变送器,使电路简单、可靠、价格低廉。由于零点可调,放大倍数稳定且可调,故可以把10℃或更窄的温度区间准确地转换为0~5V的电压输出,以供电子计算机做A/D转换用,在采用同相加法电路之后,可用数字面板表把温度准确地显示出来,代替了电压表显示,使显示结果清晰、精度也大大提高。
We design the temperature sensor, high linearity, sensitivity and stability. As a result of the more advanced integrated circuits and stable performance of single crystal thermistor, can replace the traditional platinum resistance and temperature transmitter, the circuit is simple, reliable, low cost. As the zero point adjustable, stable and adjustable magnification, it can be 10 ℃ or more narrow temperature range accurately converted to 0 ~ 5V voltage output for computer A / D converter to do with the same phase addition After the law circuit, digital panel meter can be used to accurately display the temperature, instead of the voltmeter display, the display is clear, the accuracy is greatly improved.
