how does a rudder angle indicator work
The rudder angle index is an instrument that can indicate the factual rudder angle indicator . It's equipped with lighting outfit and engraved with 350 on the left and right . It can check the delicacy and perceptivity of the steering device , and directly guide the steering action during homemade steering. The rudder angle index indicates the factual rudder angle at any time. The rudder angle index is composed of a potentiometer in the transmitter and a millivolt cadence marked as the rudder angle scale . When the rudder drives the contact of the transmitter potentiometer to rotate, the resistance of the two arms of the potentiometer changes, causing the pointer of the receiver to turn to the matching position to indicate the factual rudder angle . Feed back the factual gyration of the rudder to the hack , rudder cabin and main machine cube . The error of the electric rudder angle index is generally veritably small , as long as the error is recorded .
Rudder angle meter plays an important role in ship instrument. It indicates the rudder angle, which is usually set up mechanically and electronically. The mechanical type shall be set on the tiller, and the electronic type shall be displayed in the steering engine room and cab. When you are sailing, you need to steer the rudder and the angle of rudder rotation. It is displayed by rudder angle indicator! In order to overcome the limitations of these external environments, our company has designed and manufactured various instruments. Now the main products are rudder angle indicator, main engine tachometer, propeller pitch angle meter and so on .
Still, when in use,"rudder angle index position"must meet the ensuing conditions
1. When the main steering gear is operated by power, it shall be indicated in the hack, and the suggestion of rudder angle shall be independent of the control system of the steering gear ;
2. It can be seen in the steering gear room and the main machine cube ;
3. Within the specified steering range, the suggestion error of rudder angle index at large rudder angle shall be electric, and the error between the given rudder angle and rudder angle feedback value shall not be lesser than ± 10, and the central position shall completely misbehave with 121. Still, find out the cause, exclude it and try again until it's normal, If there's any abnormal miracle.
