product overview
SZX-F77 Vibration Analyzer
The S Z X-F77 is a dual channel vibration testing and analysis balance instrument that can collect and analyze vibration data from two channels, and store and replay data and waveforms. The instrument has functions such as vibration measurement (displaying real-time waveform diagrams and speed, amplitude, phase data), spectrum analysis (displaying spectrum diagrams, optical reading spectrum data), dynamic balance calculation (manual input or measurement transfer), and uploading data to the computer. It adopts a high-resolution LCD display screen, Chinese character menu guidance for operation, user-friendly interface, lightweight and compact instrument, easy to carry and use on site, and can meet the measurement and analysis needs of various occasions. It is suitable for people
Solving vibration problems provides powerful tools.
1. Signal input: Vibration signals can be paired with magneto electric speed sensors or eddy current displacement sensors
Key phase signal matched with photoelectric sensor or eddy current displacement sensor
2. Measurement range:
Speed range: 300-12000 revolutions per minute
Amplitude range: Displacement: 0-1000 μ m (peak to peak)
Speed: 0-1000mm/s (effective value)
Phase: 0-360 °
3. Frequency response: 10Hz ～ 1kHz
4. Display mode: 320 × 240 dot matrix graphic LCD screen
Display the vibration characteristic values, time-domain waveforms, and spectrograms of two channels, and guide the operation with a Chinese menu.
5. Vibration measurement: Switch between displaying real-time waveforms, speed, amplitude (displacement direct frequency value, selected frequency value, velocity effective value), and 1X phase of two channels
6. Spectrum analysis: 1024 point sampling
Synchronous sampling: Collect vibration signals for 8 cycles with a resolution of 1/8X when there is a key signal.
Non synchronous sampling: When there is no key signal, the sampling frequency is determined by the frequency band set by the user.

Resolution: 0.2Hz (0-100Hz), 0.5Hz (0-200Hz), 2Hz (0-500Hz)
3Hz (0-1000Hz), 6Hz (0-2000Hz), 12.5Hz (0-5000Hz), 25Hz (0-10000Hz) spectra can be obtained by moving light
7. Storage and playback: The instrument can store vibration characteristic values and real-time waveform data according to speed or time intervals, and each channel can store 200 sets of data. Press during playback
The stored count values are played back and displayed in sequence. The waveform data of the spectrogram playback is calculated from the real-time waveform data stored, and the stored data can be transmitted through the serial port
Sent to the upper computer for analysis and processing, the data can be saved in case of power failure.
8. Dynamic balance calculation: The influence coefficient method can be used for single-sided and double-sided balance calculations. The influence coefficient is known or unknown, and the amplitude and phase of the vibration can be determined
By pressing the key number input, you can also use the current vibration amplitude and phase by pressing the "ALT" key
9. Data upload: Send the stored data of the lower computer to the upper computer through the serial port, making it convenient for users to store and manage the data. At the same time, users can communicate with each other
Perform waveform display and spectrum analysis of data through upper computer software, and be able to display real-time waveforms and spectra.
10. Interface: RS232/USB
11. Working power supply: DC9V， Can be connected to an external AC-DC adapter
12. External dimensions: 275(H)×167(W)×58(D)mm
13. Weight: 550g
