Description
Technical field
The application relates to technical field of ships, particularly relates to a kind of rudder angle generating means peculiar to vessel.
Background technology
For many years, the reading instument such as helm indicator in display instrument peculiar to vessel, main engine revolution speedometer, main
Magneto-electric moving-coil instrument to be used and selsyn formula instrument.Moving-coil type gauge outfit itself can only be measured directly
Stream, but be equipped with peripheral circuit and can also measure exchange.Selsyn instrument then general volume is relatively big, gauge outfit merit
Consumption is big, needs pairing to use.In terms of angles of display, the angle changing rate of selsyn instrument is big, the most all
Exceed 300 degree, and moving-coil instrument typically reality angle table is little, about generally 90-240 degree;From line
Property is seen, due to the hairspring of moving-coil instrument, the quality of magnet steel etc., can't neglect for linear effect,
The density utilizing graduation mark is usually needed to be corrected;In terms of service life, moving-coil instrument is the most true
Point is that shock resistance is poor, and this is owing to the feature of hairspring structure determines.Selsyn instrument must be matched and be made
With, namely transmitter also must be selsyn.Although the selsyn the most also having electronic module is believed
Number conversion etc., but due to expensive, be typically rarely employed.The power consumption of selsyn is relatively big, year for a long time with
After also can aging due to coil, bearing grinds, sweep thorax etc. between rotor and stator and make instruction inaccurate or
Can not indicate;From the balanced adjustment of table, pointer gauge requires the highest, adjusts the most complicated, while it is true,
Some tables also to require " vertically " to install and use or " level " is installed and used, especially because moving-coil
The rotating torque of table, linear and table structure have the biggest relation, such as, it is necessary to use very light in weight
Indicator etc., otherwise sensitivity and being linearly all affected.
