一、前言五十年代中期,英国的阿仑·贝克(Alan Baker)发明了催化载体型接触燃烧式传感器,克服了光丝型传感器的许多缺点,成为现在还在应用的一种传感器。它也是采用铂丝绕制成的线圈作传感元件,所不同的是在绕制好的铂丝线圈上涂挂上一层陶瓷载体(氧化硅、氧化铝),烧结成型后,又往其外层涂以原素周期表中第八组的贵金属作为催化剂。这一改进带来了许多优点, I. INTRODUCTION In the mid-1950s, Britain’s Alan Baker invented a catalytic carrier-based contact combustion sensor that overcomes many of the shortcomings of the filament sensor and is now a sensor that is still being used. It is also made of platinum wire winding sensor for the sensor, the difference is in the winding of a good platinum wire coil coated with a layer of ceramic carrier (silicon oxide, aluminum oxide), sintering molding, and then to The outer layer is coated with the noble metal of the eighth group in the Periodic Table of the Elements as a catalyst. This improvement brings many advantages,
