A simple method, employing thermocouples, was developed for measurement of temperature with an accuracy of 0.05 degrees C. The method is based on the principle of a compensatory measurement of the thermocouple voltage, with application of an additional amplifier. The temperature level of the reference thermocouple was shifted from 0 degrees to 37 degrees C, using a compensating voltage. Within a smaller range (37 degrees -- 43 degrees C) the voltage of the measuring thermocouple was additionally amplified, which resulted in an increase in sensitivity and accuracy of the temperature measurement in animal tissues. The electronic circuit and calibration procedure are presented in detail.
开发了一种使用热电偶的简单方法来测量温度，精度可达0.05摄氏度。该方法基于热电偶电压补偿测量原理，并应用了一个附加放大器。使用补偿电压将参考热电偶的温度水平从0摄氏度偏移到37摄氏度。在较小的温度范围（37摄氏度至43摄氏度）内，对测量热电偶的电压进行额外放大，这使得动物组织温度测量的灵敏度和精度有所提高。详细介绍了电子电路和校准程序。
