A primary level calibration system for calibration of vibration transducers. The system, Type 3629, is an easy-to-use, automatic calibration system that provides primary calibration of a wide range of transducers. The system applies laser interferometry according to ISO 16063-11 to obtain very high accuracy.

The hardware for the basic system with Primary Vibration Transducer Calibration Software Type 5309 consists of a PULSE™ front-end with three 200 kHz channels and a dual-sine generator, power amplifier, vibration exciter, conditioners and a laser interferometer with quadrature output mounted on an air spring vibration-isolated table to filter out floor vibration. PULSE software FFT & CPB Analysis Type 7770 and PULSE Time Data Recorder Type 7708 are used to handle the recording and calculation of the vibration signals. The system is intended for National Metrology Institutes and other high-level laboratories.
