Vibration Sensor Calibration
A sensor is only as good as its last calibration. Drift, aging, and environmental exposure degrade accuracy over time. We restore your sensors to factory specifications with NIST-traceable standards and full documentation.
How It Works
Two paths to calibration.
Both NIST-traceable.
On-site with portable equipment, or factory send-back to the OEM—we match the approach to what your sensors need.
5 Hz – 10 kHz

Industrial Monitoring Sensors
Plant monitoring sensors that need regular calibration to maintain accuracy. Continuous operation and harsh environments cause drift—periodic recalibration keeps your protection systems reliable.
View Product →Industries We Serve
Oil & Gas
Rotating equipment monitoring sensors require annual calibration for safety-critical measurements.
Power Generation
Turbine vibration sensors need precise calibration for trip-level accuracy.
Aerospace
Flight test sensors must meet strict calibration traceability requirements.
Manufacturing
Production line monitoring sensors drift with temperature cycles and continuous use.
Petrochemical
ATEX/IECEx rated sensors need specialist calibration handling.
Research Labs
Reference-grade sensors demand the tightest calibration uncertainty budgets.
FAQ
Common Questions
How often should sensors be calibrated?
Most standards recommend annual calibration. Sensors in harsh environments, high-temperature applications, or safety-critical systems may need 6-month intervals.
What brands of sensors do you calibrate?
Any ICP/IEPE or charge-mode accelerometer—PCB Piezotronics, Brüel & Kjær, Endevco, Kistler, Dytran, and others. If it measures vibration, we can calibrate it.
Do you provide on-site calibration?
Yes. Our Modal Shop portable calibrators are battery-powered and designed for field use. We calibrate sensors where they're installed—no removal or shipping needed.
What documentation do I receive?
Every sensor gets an individual NIST-traceable calibration certificate with before/after sensitivity data, frequency response, measurement uncertainty, and full traceability chain. Satisfies ISO 17025 audit requirements.
How long does calibration take?
On-site portable calibration is typically completed in one day. Factory send-back turnaround depends on the manufacturer, but we offer express options and keep you informed throughout.
