Endevco 28959G portable accelerometer calibrator

Click2Contact

The Endevco 28959G is a portable calibrator for accelerometers. This self-contained system includes a built-in vibration exciter, signal generator, computer-controlled amplifier and servo mechanism, reference accelerometer, signal conditioners and necessary connectors and mounting accessories. It is designed to provide precise calibration of all types of accelerometers in the field.

The Endevco 28959G can calibrate both piezoresistive and variable capacitance accelerometers in one system. Sensor types can be selected from the built-in sensor library and the system will identify the frequency range of the selected system. The results are calculated and displayed in real time through the colour LCD screen. They can also be saved in PDF format or to USB storage devices. The calibration procedure can also be done in automatic test mode requiring little to no user interaction.

Commonly used to calibrate individual accelerometers for test and measurement, the Endevco 28959G can also be used in a wide range of process control or condition monitoring applications. It can determine whether faults are present in the measurement chain and identify which part of the process is faulty. The 28959G can also be used as a standalone shaker that can assist engineers to check the performance of individual components separately in the system and identify the root cause.
