PORTABLE VIBRATION CALIBRATOR AT-2040
Portable Vibration Calibrator AT-2040
With the AT-2040 you will find the functions you need for your application without having to install cumbersome and costly add-ons.
The AT-2040 features a fully automatic sensitivity test mode, signal simulation, power supply output for sensors requiring voltage, such as the 7310 and 991V aviation sensors, a built-in sensor load amplifier for single-ended and differential load accelerometers, and a custom sensor input that can be configured to fit most accelerometers with a one-to-one cable.
Main Functions
AT-2040 Portable Calibrator
Vibrate or excite a transducer under test:
In vibration mode, the AT2040 can be used as a vibrator with variable frequency and amplitude. In this mode, the user manually adjusts the frequency and amplitude, while the device provides high-precision measurement signals.
Calculate the sensitivity of the transducer:
By comparing the signals sent to the reference accelerometer by the signal generation board and the signals returned by the transducer under test, the AT2040 can automatically determine the sensitivity of the test transducer with a high level of accuracy.
Generate a calibration certificate traceable to NIST:
Once the sensitivity over the entire frequency range of the test transducer has been calculated and stored, the AT2040 will generate a NIST-traceable certificate and graph in PDF format. This certificate is stored in the computer’s memory and can be retrieved and exported at any time to a USB flash drive.
Simulate a transducer using a precision signal generator (function generator):
The AT2040 is capable of producing signals over a wide amplitude and frequency using its built-in amplifiers to simulate a variety of load and voltage signals. This allows the user to simulate a transducer in operation and is the ideal tool for electronic testing, troubleshooting or calibration of condition monitoring systems.
