The Versatility in Vibration Measurement Datasheet

Transcription

1 OFV-5000 Vibrometer Controller The OFV-5000 Controller is the core of Polytec s latest state-of-the-art laser vibrometer systems. Its modular design allows the frequency, velocity and displacement capabilities to be tailored to your applications. Both analog and digital decoders are available, giving a frequency from near DC to 4 MHz, with veloci ties up to ±0 and displacements from the picometer to meter. In combination with an interferometric sensor head OFV-505 for highest signal quality, OFV-534 compact sensor head or OFV-55/55 fiber-optic sensor heads, the OFV Modular Vibrometer is an ultra-precise workhorse for non-contact vibration measurement. Highlights Measure displacement and velocity in real-time High resolution and bandwidth Flexible and expandable with several sensor heads and decoders Simple and comfortable operation with touchscreen and remote control OFV-5000 Vibrometer Controller The Versatility in Vibration Datasheet

3 System Configuration Different analog and digital decoders ensure that the OFV-5000 Vibrometer Controller fits perfectly to your application. With a combination of up to four decoders the Modular Vibrometer system shows its high flexibility. Therefore the OFV-5000 contains four slots: two for velocity decoders, one for the displacement decoder and one additional auxiliary slot for a velocity or a displacement decoder.
