The ifm VK Vibration Monitoring
Switch is designed to permanently mount on a machine to continuously monitor
the machine's vibration level. By detecting vibration level changes when they
first occur, the VK can help to prevent equipment from catastrophically
failing, reduce secondary damage, and eliminate expensive downtime. The compact
VK switch measures only 73 mm high and features two setup dials that rotate to
quickly establish the maximum velocity setpoint and time delay. The switch
combines both switching function and transmitter into one small housing. It is designed
to monitor vibration on motors, pumps, compressors, fans, centrifuges and
vibratory feeders. It also offers the advantages of a high performance
vibration monitoring device at a fraction of the price - only $219 (US). The 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 - 1000 Hz. Most moving
components on typical motor-driven equipment from 600 to 3000 rpm will fall
within this frequency range. The VK
switch integrates cost effective MEMS technology, and software is not required
for configuration .In just 5 min, a vibration monitoring switch can be
installed and ready for operation. Compared to complicated vibration diagnostic
systems and Smart accelerometers, the ifm VK vibration switch makes
implementing vibration monitoring easy and straightforward. Setup is simple
using the switch's rotating setup dials that establish maximum velocity
setpoint and response time delay. Highly-visible LEDs provide output status of
power and alarm if the setpoint is exceeded. An analog output enables trending
of vibration levels. With the switch's MEMS technology, the VK switch provides
a cost-effective solution that previously was only available at a high price.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
