The air-speed tube of double-wire armored heater is a new type of air-speed tube of armored heater developed recently.Its heater is a closed loop,insulated from the product shell,and its safety,compatibility and error prevention functions are better than those of single-wire airspeed tube products.This type of airspeed tube has been widely used in all kinds of aircraft,such as UAV,missile,transport aircrafts,small aircraft,etc.It is widely used,the order quantity increases greatly,and the market prospect is broad.Based on the analysis of the various factors affecting the airspeed tube insulation resistance of the double-wire armored heater and the action mechanism of these factors on the insulation resistance,this paper puts forward the control measures of the influencing factors in order to improve the qualified rate of the airspeed tube insulation resistance of the two-wire armored heater.
