高精度恒温恒湿空调应优先采用相对湿度传感器自动控制系统。肠衣膜片是感湿敏感元件的良好材料,它制成的敏感元件,具有感湿面大,灵敏度高、机械强度大、制作简单、成本低、使用周期长等优点。本文简要介绍膜式湿度传感器的制作过程以及相应的自动控制系统,经过长期生产运行实践证明该元件及控制系统,方便可靠能够达到高精度空气调节的要求。 High-precision constant temperature and humidity air-conditioning should give priority to the relative humidity sensor automatic control system. The casing membrane is a good material for the moisture sensitive component. The sensitive component made of it has the advantages of large wet surface, high sensitivity, high mechanical strength, simple manufacture, low cost and long service life. This article briefly introduces the manufacturing process of the membrane humidity sensor and the corresponding automatic control system. Through long-term production and operation practice, this component and the control system have proved that it is convenient and reliable to achieve high-precision air conditioning requirements.
