一种新型的红外式纸页水份在线测试仪.该仪表采用红外水份测量原理,信号处理上利用了比尔定律进行非线性补偿.在系统结构的设计上,提出了采用两个固定光路来取代调制盘;采用两级精密温度控制技术来消除敏感原件的温漂以及数字信号传输等项技术使得该仪表不仅具有很高的精度而且还具很强的抗干扰能力和很高的可靠性.
A new type of infrared paper water online tester.This meter uses infrared moisture measurement principle, the signal processing using Bill’s Law for nonlinear compensation.In the system structure design, the use of two fixed optical path to Replace the modulation disk; the use of two precision temperature control technology to eliminate the sensitive components of the original drift and digital signal transmission technology makes the instrument not only has high accuracy but also has a strong anti-interference ability and high reliability.
