医学动物实验热源仪的研制

Development of a heat source instrument used in animal experiments

本文描述了一种以 =3mm小直径半导体PN结作为热传感器 ,测温范围0～45℃ ,测量分辨率为0.1℃,具有64通道 ,用于测量医学实验动物体温的热源仪。由于采用两点总体温度标定方法 ,使硬件电路调整极为方便。采用这种标定方法是本仪器的特点。

This paper describes a heat source instrument used in animal experiments. It has 64 channels with sensitivity of 0.1℃.It is convenient in temperature calibration due to its software calculation.
