Vibration calibrators produce sinusoidal mechanical vibration signals with known amplitudes and frequencies that can measure acceleration, velocity, and displacement of vibration sensors and other general test equipment.
Vibration Calibration Equipment
Vibration calibrators can conduct loop checks and troubleshooting for accelerometers and quickly diagnose sensor drift in the process of confirming correct vibration alert operation. Some vibration calibrators also have built-in memory for generating calibration reports, providing maximum convenience for auditors and risk engineers.
Vibration Calibration Functions
Vibration calibrators are used to measure acceleration, velocity, and displacement of equipment like vibration sensors or other test instruments. Most vibration calibrators can test with a frequency range of 5 Hz to 10k Hz, in compliance with the ISO 17025 standard, or 16 Hz up to 640 Hz, according to ISO 8041 standard. Some calibrators feature different test modes, such as Shake Mode, Test Mode, Simulate Mode.
- Shake Mode: ideal for performing end-to-end checks
- Test Mode: display sensitivity reading for accelerometers and proximity probes
- Simulate Mode: wider range testing and more accurate
Vibration Calibrator Applications
A vibration calibrator can measure a wide range of equipment. They can calibrate instruments with a specific frequency range. Depending on the manufacturer and model, some can generate calibration certificates. They can measure:
- Proximity probe
- Velocity sensors
- Displacement sensors
- Vibration meters
- Vibration sensors
- Vibration monitoring systems
- Vibration analyzers
How to Choose The Best Vibration Calibrator
When choosing a vibration calibrator, it is crucial to consider the specifications and features of the equipment. Choose a vibration calibrator testing needs and your testing objects. The features listed below can be useful references in selecting the best vibration calibrator for you:
- Portability (handheld)
- Maximum load
- Velocity output
- Acceleration output
