Vibration Transducer Calibration System Type 3629 is an easy-to-use, automatic calibration system that provides traceable calibration of a wide range of transducers.
The hardware for the basic system shown in Fig. 1 consists of a Portable PULSE front-end, which provides the necessary inputs and generator output, a power amplifier and a shaker. The front-end is connected via Ethernet to a standard PC (desktop or laptop). Furthermore, a Reference and a Working Standard transducer are required, with suitable preamplifiers if they are not DeltaTron transducers (transducers with constant current supply) or voltage output types. The standard reference transducer used in the mid-frequency range is Type 8305-001 with Charge to DeltaTron Converter Type 2647.
