Be example with the servo obliquity sensor of force balance type below, analyze the measurement of dip angle principle.
The servo obliquity sensor of force balance type is made up of non-contact displacement sensor, torque-motor, sum of errors amplifying circuit, feedback circuit, cantilever mass five parts.The armature of cantilever mass and torque-motor links together.Non-contact displacement sensor is used to detect the displacement and the direction of mass.When the whole sensor run-off the straight, the cantilever mass just leaves original equilibrium position, after non-contact displacement sensor detects this variation, position signalling is sent into the sum of errors amplifying circuit, on the one hand sensor output and the proportional simulating signal in inclination angle; On the other hand, this signal is sent into the coil of torque-motor through feedback circuit, and at this moment, torque-motor can produce opposite, an equal-sized moment with cantilever mass direction of motion, tries hard to make the cantilever mass to get back to original equilibrium position.Through after the regular hour, the cantilever mass just rests on the new equilibrium position like this, and at this moment, the signal of sensor output is only real effectively signal.This output signal is generally d. c. voltage signal, also can change by built-in V/I output 4～20mA signal.
No matter the output of sensor is voltage or current signal, all becomes sine relation with the angle value that expenditure is represented.That is to say, be that measurement unit represents that angle value is with degree, minute, second directly, the voltage or the current signal of sensor output must be carried out the inverse sine computing.
In the servo obliquity sensor of force balance type, torque motor is commonly used to the acceleration of the angle motion of sensing aircraft in allowed band or the variation at inclination angle.When having acceleration or inclination angle, have one with the proportional moment of mechanical imbalance, produce the input of physics, this moment produces an angle motion can be by an optic position sensor sensing.This position transducer output is compared with a reference voltage, and its difference is imported servoamplifier as error signal.The servoamplifier output current is sent into torque motor, and is opposite with original acceleration or inclination angle moment direction.When input during an inertia constant, the position of the position, angle of torque motor during with 0g is slightly different.Servo amplification output current is directly proportional with the sine at input acceleration or input inclination angle, measures the servo current that passes through by pull-up resistor and obtains an aanalogvoltage.
