Dynamic transmitters, instruments, and vibration measurement systems.

3）Havingmanual calibrationFunction: Can manually set the frequency and amplitude digitally, output any vibration for precision

Detailed personalized calibration;

4）HavingAutomatic verificationFunction: By running onPCThe 'Vibration Calibration Platform Measurement and Control Software',

After setting up and editing the amplitude accuracy verification and frequency response test program and downloading it to the vibration verification table, it can

Fully automated testing and calibration of the calibrated vibration sensor and measurement system.

5）Can be placed horizontally or vertically for use in order to verify vertical or horizontal sensors. High output thrust, firm

Solid suspension vibration system can support mass1000gramVarious sensors inside.

★ Number given, automatic adjustment, easy operation

1）By using the keyboard, the vibration frequency and amplitude can be arbitrarily set with numbers, which is more convenient and accurate than traditional potentiometers or band switches.

2）After the vibration frequency and amplitude are given, the digital servo system automatically adjusts to quickly obtain the desired vibration.

3）During operation, the setting and frequency can be adjusted digitally at any time.

★ Low distortion, high stability, high precision, and good frequency response performance

1）High precision digital signal excitation source with low output distortion and good stability.

2）Built in displacement sensor for low frequency standard and acceleration sensor for medium frequency standard, with excellent frequency response.

3）Based onDSPThe digital servo automatic adjustment and standard vibration measurement have strong ability to suppress output disturbances and have a high response

Fast response, high precision in output vibration amplitude and frequency, and good low-frequency characteristics.

4）In20~200HzWithin the range, the frequency accuracy reaches0.02%,The amplitude accuracy is better than ±3One word (far, far, high)

Compared to similar products both domestically and internationally3dB）.

★ Humanized configuration, lightweight and portable structure

1）Configure a complete set of specially designed brackets and accessoriesIt can meet the installation needs of various vibration sensors.

2）The system integrates other necessary instrument functions for vibration verification:
