Accelerometer & Vibration Sensor Calibration
NIST-traceable calibration of accelerometers, velocity sensors, proximity probe systems and 4–20 mA transmitters, from any manufacturer. Sensitivity and frequency response from 5 Hz to 10 kHz, with a PDF certificate for every sensor.
- Any brandof vibration sensor
- 5 Hz – 10 kHzfrequency response
- ~1 weektypical turnaround in the lab
- NISTtraceable certificate
Sensors we calibrate
Each sensor is calibrated by back-to-back comparison against a NIST-traceable reference accelerometer on our electrodynamic shaker.
| Sensor | What we measure | Notes |
|---|---|---|
| IEPE accelerometers | Sensitivity (mV/g), frequency response, bias voltage | ¼-28, 10-32, 2-56 and 6-32 mounting adapters on hand |
| Charge accelerometers | Sensitivity (pC/g), frequency response | Measured with a built-in charge amplifier |
| Voltage, MEMS and piezoresistive accelerometers | Sensitivity, frequency response | Differential outputs through our MEMS-100 adapter |
| Triaxial accelerometers | Each axis: sensitivity and frequency response | Each axis tested in turn |
| Velocity sensors, piezo and moving coil | Sensitivity (mV/in/s or mV/mm/s), frequency response | Universal velocity adapter for most housings |
| Proximity probe systems | Incremental scale factor over the linear range, gap voltage, dynamic response | Probe, extension cable and driver tested together against a 4140 steel target |
| 4–20 mA vibration transmitters | Loop current against applied vibration | Loop powered at +24 V during the test |

The AT2040 runs the same back-to-back tests on site: it powers and reads the sensor, sweeps up to 40 test points automatically and creates the PDF certificate. Use it for routine checks in-house, and send sensors to us when you need an outside calibration.

Sensor calibration questions
Which brands of sensor do you calibrate?
Any manufacturer, as long as the sensor mounts on our shaker and its output is one of the types listed above. Tell us the model when you ask for a quote.
Is sensor calibration accredited?
Sensor calibrations are NIST traceable. Our A2LA accreditation to ISO/IEC 17025:2017 covers the calibration of portable vibration calibrators, not sensors.
How long does it take?
About one week in the lab is typical, plus shipping time each way. We confirm the timing with your quote.
What frequency range can you test?
From 5 Hz to 10 kHz. The usable range for a given sensor depends on its mass and mounting, so heavy sensors may be tested over a narrower range or at lower levels.
What should I send for a proximity probe calibration?
Send the probe, its extension cable and its driver together, so the system is calibrated as it is installed. We test against a 4140 steel target, the material most probe systems are calibrated for.
Can you use my test points?
Yes. Give us your reference frequency (a whole number from 5 Hz to 10 kHz) and up to 40 frequency and amplitude points per sensor, for example the points on your sensor's original certificate.
