超声控制器与其它形式的控制器相比,其独特之处在于这种控制器不产生电磁辐射,不会干扰附近的无线电控制系统或其它无线电敏感设备;当然这种控制器本身也不受外界无线电系统的干扰。另外,它还不易受污物和灰尘的影响,因而又比光束控制系统优越得多。基于上述特点,超声控制器有 Ultrasonic controllers are unique over other forms of controllers in that such controllers do not generate electromagnetic radiation and do not interfere with nearby radio control systems or other radio sensitive devices; of course, such controllers are not themselves exposed to the outside world Radio system interference. In addition, it is less susceptible to dirt and dust and is therefore far superior to a beam control system. Based on the above characteristics, the ultrasonic controller has
