Vibration Switches / USB Transmitters Application The VS1x has functions which are not found in common vibration switches. All devices can be programmed via a USB port. They feature peak and RMS vibration monitoring with selectable frequency limits. There is a relay output for switching external loads. In addition models VS11 and VS12 allow monitoring in frequency domain. The frequency spectrum is measured and compared to individual amplitude limits in 10 user-selectable frequency ranges. The VS12 has an external USB socket. It can be directly connected to PCs for quick and simple vibration measurements. The devices include piezoelectric accelerometers providing high precision, good resolution and a wide frequency range. Typical applications are: • Vibration monitoring of motors, fans, pumps, compressors etc. to ISO 10816 / 20816 • Quality control in production • Emergency shut-off in production installations where vibration may endanger personnel and equipment • Monitoring vibrations as part of process control • Protection of fragile goods during transportation • Vibration monitoring at rail vehicles • Safety switch at doors, gates etc. Properties • Monitors vibration acceleration and velocity • 60 frequency ranges from 0.1 to 10 000 Hz for RMS and peak values programmable • Frequency analysis from 2 Hz to 1000 / 10 000 Hz (VS11/12) • Indication of warning and alarm by flashing LEDs (VS10 / VS11) • Teach-in function for automatic threshold setting • Rugged aluminum case • Water proof to IP67 • Simple attachment with M8 stud bolt
