本文介绍过去描述过的温度控制器的一种简化型式的电路。为了可以与中等或者高欧姆值的电阻传感器(低温锗温度计或者室温铂温度计)一起使用,设计了适用于低阻传感器的四端子交流电桥。当传感器电阻充分小(R_X<100Ω)时,我们可以省去过去在电桥那一节(参考文献1中的图2)里所用的精密引线电阻补偿电路,而采用一种更简单的设计,这种设计对引线电 This article describes a simplified version of the temperature controller described in the past. In order to be used with medium- or high-ohmic resistance sensors (low-temperature germanium thermometers or room-temperature platinum thermometers), four-terminal ac bridges for low-impedance sensors are designed. When the sensor resistance is sufficiently small (R_X <100Ω), we can eliminate the need for a precision lead-resistance compensation circuit that was used in the bridge section (Figure 2 in Ref. 1), but with a simpler design, This design leads to the wire
