VK Series vibration switch

The VK Series vibration switch from ifm efector is designed to continuously monitor the vibration levels of critical plant equipment to help prevent machine failure and expensive downtime. The compact VK switch is designed to permanently mount on a machine to provide continuous feedback of vibration level via a 4-20 mA analog output.

By detecting vibration changes when they first occur, the VK switch can prevent equipment from catastrophically failing, reduce secondary damage and eliminate expensive downtime.

The VK vibration switch eliminates the challenges with traditional vibration monitoring such as spectrum analysis and data collectors. Implementation is based on the ISO10816 standard which defines vibration monitoring of machinery. Based on this standard, the VK monitors the frequency range of 10 Hz to 1000 Hz and is adjustable for the maximum allowable vibration in the unit by RMS velocity. The ISO standard makes it easy to implement vibration monitoring without complex methods or equipment.

Set-up is achieved using two set-up dials that rotate to adjust the maximum RMS velocity setpoint and response delay time. The switch provides an alarm if the setpoint is exceeded. Highly visible LEDs provide local indication for power and alarm conditions.
