Vibration and Shaker System Repair

Techmaster repairs vibration test equipment: electrodynamic shakers and amplifiers, vibration controllers, accelerometers and vibration meters. After repair, each instrument is calibrated before it is returned; vibration calibration from 0.2 to 36 g peak and 1 Hz to 10 kHz is on our ANAB ISO/IEC 17025 scope at the Santa Clara laboratory.

We repair instruments from many manufacturers, including older and discontinued models where parts are available. Techmaster is an independent laboratory, not a manufacturer-authorized service center.

Vibration manufacturers we know best

Techmaster has completed 1,002 vibration calibrations in the last ten years across 209 instrument lines. These are the manufacturers whose instruments we calibrate most often:

Common vibration faults we see

  • Accelerometer sensitivity shift or failure after a drop or a shock beyond its rating.
  • Damaged connectors and cables, the most common cause of noisy or intermittent vibration signals.
  • Shaker armature, flexure or suspension fatigue, heard as rattles or seen as cross-axis motion and lost stroke.
  • Power amplifier output-stage faults, failed fans and interlock trips.
  • Vibration controller input channel faults, found when two channels disagree on the same signal.

How does a repair work?

Send the make, model and serial number with a description of the fault and any error codes. We diagnose the fault and send a quote with the expected timeline and warranty terms for your approval. After repair, the instrument is calibrated and returned with its certificate.

What calibration comes after the repair?

Vibration calibration is on the ANAB ISO/IEC 17025 scope at the Santa Clara laboratory only, covering 0.2 to 36 g peak from 1 Hz to 10 kHz. Sensors or frequencies outside that range are certified NIST-traceable. Exact ranges and uncertainties are on our published accreditation scope.

Need to keep testing while your instrument is away? You can rent vibration test equipment for the repair period.

Frequently asked questions

Can you repair a shaker or vibration controller?
Yes. Send the make, model and a description of the fault, and we reply with a quote, the expected timeline and the warranty terms. Ask us about on-site work for installed shaker systems.
Where is vibration calibration accredited?
At Techmaster's Santa Clara, California laboratory, covering 0.2 to 36 g peak from 1 Hz to 10 kHz on our ANAB ISO/IEC 17025 scope.
Can you repair a vibration controller?
We repair vibration controllers where parts are available and calibrate them after repair. Vibration control systems are among the vibration items we calibrate most often. Send the make, model, channel count and the fault or error message for a quote.
Should an accelerometer be repaired or replaced?
Many piezoelectric accelerometers are sealed, so repair is often limited to connectors and cables. If sensitivity shifted after a shock, recalibration shows whether it is still usable. Tell us the model and what happened, and we advise on repair, recalibration or replacement.
Is Techmaster an authorized service center?
No. Techmaster is an independent repair and calibration laboratory, not a manufacturer-authorized service center. It repairs instruments from many manufacturers, including older models, where parts are available.
How long does a repair take, and is there a warranty?
It depends on the fault and on parts availability. We include the expected timeline and the warranty terms with the quote.
