kus stainless steel rudder angle indicator gauge dc
The kus stainless steel dc rudder angle indicator gauge is an essential equipment for various small and medium-sized ships sailing at sea, and its main function is to transmit the rudder angle position information of the ship during navigation to the cockpit, rudder cabin, and other places that need to be viewed. This system device has the advantages of high accuracy, low working noise, and intuitive indication. This device can be equipped with VDR signal output and can be equipped with multiple repeaters (requiring a junction box).

The kus stainless steel rudder angle indicator gauge is an instrument used to measure and display the rudder blade angle and direction of naval vessels, and most existing ships still use a self adjusting steering engine indicator system. This type of rudder angle indicator is mainly used for indication systems with low accuracy, but its indication accuracy, noise level, manufacturing cost, and maintenance and repair requirements all have obvious shortcomings. Firstly, the selsyn type rudder angle display system units are mostly composed of small asynchronous motors with single-phase excitation windings, cable cables, and indicating instrument panels. The system wiring is relatively complex and requires high voltage power supply, resulting in high energy consumption and high probability of failure; Secondly, the indication accuracy of such rudder angle gauge indication systems is not high. The stator and rotor coils of the synchro adopt micro sliding rings, which have poor contact problems. The indicator needle uses an electromagnetic mechanism, which is prone to interference from external magnetic fields and requires frequent zero calibration, resulting in insufficient accuracy; Once again, in terms of economy, this type of rudder angle gauge indicator has a higher cost.
The electronic rudder angle meter detects the angle signal of the rudder angle through an angle sensor, and then performs A/D conversion in a microcontroller. According to a pre designed program, the corresponding signal is output after calculation, and the position of the rudder angle gauge is displayed on a LCD display. Digitalization of ship rudder angle gauge and display has been achieved.
