rudder angle indicator kit
The transmitter shell of the rudder angle indicator is provided with a coding disc , the indexing line of the coding disc is provided with a coding hole and a reading control hole, the center of the coding disc is provided with a transmission shaft , the transmission shaft is provided with a pulley , one side of the coding disc is provided with a light source transmitting assembly , the other side is correspondingly provided with a photoelectric receiver , and the light emitted by the light source transmitting assembly passes through the coding hole and the reading control hole , Make the corresponding photoelectric receiver generate the encoded data level data signal (data pulse signal) and reading control level signal (reading control pulse signal). After phase inversion amplification and phase inversion shaping, the data level signal is stored in the latch of the transmitter under the control of the reading control level signa , and the locked parallel data pulse, The serial data pulse is converted into serial data pulse through the in / out shift register of the transmitter, and the serial in / out shift register of the input display is converted into parallel data and stored in the latch of the display. The output parallel data is divided into two channels, one is sent to the decoding driver to drive the display angle of the display screen , the other is sent to the zero position and direction recognition circuit, and through the direction display driver , Driving the display direction, the whole data transmission and conversion are carried out synchronously under the control of the main oscillator clock pulse generator and the control pulse and clock pulse generated by frequency division .
For many years , the rudder angle indicator , main engine tachometer and other indicating instruments in marine display instruments mainly adopt magnetoelectric moving coil instrument and self-adjusting angle machine instrument . The moving coil meter itself can only measure DC , but it can also measure AC with peripheral circuits . The self-adjusting angle instrument is generally large in volume and large in power consumption, so it needs to be used in pairs .
Our Rudder Angle Indicator has the advantages of accurate indication , sensitivity and reliability , is not affected by voltage fluctuation , is simple to adjust , and is suitable for various ships .
