The safety strap which is included with the analyzer should be checked for condition prior to each use. Most safety straps use Velcro and the Velcro is there for your safety. The strap is designed to separate to prevent injury should your cables become tangled in the rotating shaft or some other moving part of [...]
An accelerometer is often used with a magnet to couple the sensor to the machine. The coupling between the magnet and machine is critical to ensure quality vibration data is acquired. Placing the magnet onto the machine can create an impact which can shock the sensor for several seconds. Collecting data during this time can [...]
In today’s industry, predictive maintenance plays a big role in keeping machinery operating in peak condition. Many maintenance departments strive to have a first class predictive maintenance program; they do this by collecting data on a continuous basis through routes with handheld data collectors to evaluate the health of the machines that are needed to [...]
Frequency can be defined as how often an event occurs per unit of time. A vibration spectrum is displayed as a horizontal and vertical plot (X and Y). The horizontal (X) axis is the frequency axis and shows a representation of how often an event occurs. Typically, the vibration analyst may use multiple units of [...]
MYTH: “It is acceptable to use a stinger attached to the vibration sensor.” TRUTH: Stingers can be attached and used with most vibration sensors. However, stingers are the least desirable method to mount the sensor to the equipment. Stingers reduce the frequency range that can be measured with the attached sensor. Also, it is very difficult to [...]
If, based upon your vibration data, you suspect that a motor has an electrical defect, then you can perform a quick verification check using your vibration data collector. Place your vibration data collector in a live mode or continuous measurement mode. Turn off the electric power to the motor. Any electrically induced vibration should cease [...]
