AT2040 Portable Vibration CalibratorSmart shaker, sensor test set & signal simulator

Lab-grade accuracy in the field. The Gen 2 AT2040 calibrates accelerometers, velocity sensors, proximity probes and 4–20 mA transmitters on site, then generates the calibration certificate. A calibration shaker, sensor test set, bearing fault simulator and signal generator in one rugged, battery-powered case.

Try the AT2040 right here.

The AT2040's interface, rebuilt in your browser from the unit's own screen layouts. Tap through it the way you would on the bench.

  1. Tap any mode on the Select Mode screen. Every mode works.
  2. In Vibration Output, pick a Channel and Units, press Start and watch the sensitivity appear.
  3. In Sensor Test, pick a sensor and run a full automatic test, then find it in Reports.
  4. Use the knobs like the real ones: turn to scroll or adjust, press right to select, press left to go back.
How it works

It measures the vibration. It doesn't assume it.

Most portable shakers set a drive level and trust it. The AT2040 has its own reference accelerometer under the shaker head that measures the real motion all the time.

Your sensor's output is compared against that measured motion, not against the setting. Mass loading, a loose mount or a bad cable show up on screen straight away, as a change in live vibration, amplifier load or distortion.

Sensor Test

Automated sensitivity testing

Pick a test, press start. The AT2040 steps through each frequency and amplitude, measures the response and calculates sensitivity and deviation at every point. You don't need a PC, software or a spreadsheet.

  • Automatic frequency and amplitude control
  • Live sensitivity, bias and deviation
  • Repeatable test points with no user input
  • PDF certificate and CSV export from the device
Not just accelerometers. The same automatic tests run dynamic proximity probe checks, including amplitude sweeps and scale factor. Prox probe testing →

Bearing Defect

Diagnostics & training

A real bearing fault is a sharp impact followed by a short ring-down, repeated every time a rolling element passes the defect. The AT2040 produces that same pattern, steadily and repeatably, so you can check alarm thresholds and envelope detection without a damaged bearing.

  • Outer race, inner race and cage faults
  • Set amplitude, shaft speed and ball count
  • Defect frequency calculated from ball count and speed
  • Impact transmitter testing coming in 2027

Sensor Simulation

System validation

Unplug the sensor and let the AT2040 pretend to be one. Feed a known signal into a monitoring system to check channels, scaling, alarms and cabling without shaking anything.

  • Voltage and charge signals, 1 Hz – 11 kHz
  • Adjustable 4–20 mA output
  • Proximity probe signals
  • No external signal generator needed
COMING IN 2027Impact transmitter testing

Make the knocks. Count them too.

Coming to the AT2040 in 2027: generate real impacts on the shaker and read the impact transmitter the way a handheld impact meter does, so you can prove the whole channel end to end, from knock to loop current.

Raise the knock strengthThe loop current starts to climb exactly when the knocks clear the threshold.
2
Raise the knock rate+1 mA per knock in each reset window. Walk it up to alarm (8 mA) and trip (12 mA).

Knock size here is made up for illustration. On a real rig, how drive strength turns into sensor mV depends on the transmitter and how it sits on the table.

Network & script control

Automate it. Run calibrations from a script.

Connect over Ethernet or Wi-Fi and drive the AT2040 with plain-text commands: pick the sensor, run the autotest point by point, and pull back CSV and PDF results. Or take over its screen with VNC.

1ConnectWired Ethernet, or Wi-Fi with a USB adapter. Find the IP address on the unit's Network Settings screen.
2Open TCP portPlain-text, case-insensitive commands. Any TCP client works: Python socket, LabVIEW, nc.
3Test & exportSelect the sensor and serial, run the autotest with step-by-step control, then export CSV or the PDF certificate.

FAQ

AT2040 questions, answered.

What sensors can the AT2040 calibrate?

The AT2040 reads the analog output of IEPE, charge and voltage (AC/DC) accelerometers, piezo and moving-coil velocity sensors, eddy-current proximity probes and 4–20 mA vibration transmitters. Piezoresistive and variable-capacitance MEMS sensors are supported with the MEMS adapter. It also supplies sensor power: 2–24 V programmable, −24 V for probe drivers and +24 V for loop-powered transmitters.

What is the AT2040's frequency range?

Vibration output runs from 5 Hz to 10 kHz. Signal simulation runs from 1 Hz to 11 kHz.

Is AT2040 calibration accredited and traceable?

Yes. Calibration is A2LA accredited to ISO/IEC 17025:2017 and NIST traceable. Annual recalibration is recommended.

Can the AT2040 create calibration certificates?

Yes. Automatic sensor tests produce PDF calibration certificates and CSV data straight from the instrument, with no PC or software needed. The certificate template can be customised with your own layout and company logo.

Can I control the AT2040 remotely or from a script?

Yes. Connect over Ethernet or Wi-Fi and send plain-text commands over TCP from Python, LabVIEW or any TCP client to select sensors, run autotests step by step and export results. You can also operate the touchscreen remotely with VNC.

Can the AT2040 simulate bearing faults?

Yes. Bearing Defect mode generates outer race, inner race and cage fault impulses. You set the amplitude, shaft speed and ball count, and the unit calculates the defect frequency.

What battery does the AT2040 use?

A 12 V 6 Ah LiFePO4 battery rated for about 5,000 charge cycles, with a built-in 100–240 V smart charger.

What is the difference between the AT2030 and the AT2040?

Both are Gen 2 portable vibration calibrators with the same 5 Hz – 10 kHz shaker. The AT2030 is a traceable reference vibration source. The AT2040 adds sensor inputs and power, live sensitivity, automated tests with certificates, and signal simulation.
