数字质量厚度传感器温度特性分析与控制

The Temperature Character Analysis and Control for Digital Mass-thickness Sensor

分析了温度变化对质量厚度传感器的影响，利用热管高效的传热性及极好的导热性特点，提出了采用半导体制冷器和热管散热的控温技术，将该技术用于实际，给出了温控仪表的性能曲线，表明采用此技术仪表性能大为提高。

The influence of temperature shift on mass-thickness sensor is introduced. Combining with a high efficient and rapid heat transfer device,thermal tube,a new practical technique for instruments temperature control is also proposed. By using this technique to the practice,the performance graph of the controlled sensor is given.
