DEVICE FOR CONTROL OF ADDITIONAL NONLINEARITY OF MICROELECTROMECHANICAL CONVERTERS OF LINEAR ACCELERATION AT THE TEST FOR VIBRATION RESISTANCE

摘要

A device for monitoring additional nonlinearity of linear acceleration transducers during vibration resistance testing, comprising a vibrator fixedly mounted on a device that is fixedly mounted on the shaft of the goniometer device, a vibration sensor and a tested microelectromechanical linear acceleration transducer, the output of which is connected to the input of the converter, the output of which is fixed connected to the input of the computer, the output of the vibration sensor is connected to the input of the oscilloscope and to the measurement input of the vibrator, the output of the vibrostand generator is connected to the input of the vibrostand amplifier, the output of which is connected to the vibrator input, characterized in that the adjusting screws, the level and the vibration damper that is installed between the shaft of the goniometer and the device plate are inserted, using the adjusting screws in which put in a horizontal position the vibrator table, which is controlled by the level.
