AT-2050 Accelerometer Test System

Our newest product in the Portable Vibration Calibrator lineup, the AT-2050 Accelerometer Test System is designed to provide precision calibration of velocity pickups, transmitters, IEPE accelerometers, piezoelectric accelerometers, both single-ended charge accelerometers and differential output charge accelerometers, piezo resistive (PR) accelerometers, and variable capacitance (VC) accelerometers. AT-2050 is the only calibrator capable of measuring these signals directly without external equipment or external charge signal converter. AT-2050 is a fully self contained, loop controlled, system with a vibration exciter and amplifier.

AT-2050 also features the same award winning simulation feature found on our AT-2040 model for simulation of various sensor types. This is the fastest and most efficient way to test and calibrate meters, control equipment, or cables.

The shaker includes 8 mounting adapters consisting of, 5 threaded adapters, one adhesive mount, and two universal disc – one for velocity pickups and the other for triangular accelerometers.

The AT-2050 features full automatic test mode that requires absolutely no user interaction. Simply setup your required frequency and amplitude plot points and AT-2050 does all the work for you. Results are saved to the 16 GB internal memory with virtually unlimited report storage capabilities. Certificate test can then be exported in PDF or CSV.


The Only Portable Vibration Calibrator Capable of Calibrating Piezo Resistive and Variable Capacitance Accelerometers Directly

The AT-2050 is packed with features and functionality, it is also the only calibrator available to test PR and VC sensors.

Simulate Accelerometer Output with the Built-in Vibration Signal Generator


BNC sensor output, IEPE, charge modes

AT-2050 features a built-in Vibration Signal Generator capable of producing high-accuracy electrical signals over a wide frequency and amplitude range. Designed specifically to simulate accelerometer output, the AT-2050 accelerometer calibrator features the ability to simulate current, voltage, and charge signals that precisely mimic a variety of transducers and sensors. Simulation mode allows signals that would not be possible otherwise due to the vibration shaker limitations.
