Location, Location, Location

When it comes to analyzing vibration, sensor placement is key to quality of data capture. Motors can be large, surrounded by equipment and difficult to access, so locating an area to place your vibration sensor can be harder than it looks.

Motion Amplification Case Study: Structural Looseness

This case study features a convection oven fan used in the customer's production process. Multiple welds and other repairs were made prior to the inspection. A service team was called in to balance the fan, but with Motion Amplification it quickly became clear that there was a serious structural issue.

Case Study: Cooling Tower Vibration Monitoring

Cooling towers are a critical component in many process facilities and contain several pieces of rotating machinery that contribute to their operation. Motors, gearboxes, fans and shafts require vibration monitoring to provide technicians with early warning signs of impending failures that could lead to catastrophic breakdowns.

Using Baseline for Analysis

When you measure on your machine, the results may vary even if no defects are present. That is just normal behavior. This video will discuss how using baselines in analysis can be beneficial in keeping machines healthy.

Accelerometer Maximum Cable Length Calculator

When cables between the power supply and the accelerometer are short, less than 100 feet or 30 meters, circuit capacitance usually has no significant effect on the vibration data signals. Long cables may introduce sufficient capacitance into the sensor circuit to allow vibration signal distortion and produce spurious signals.

Why Use 1000Hz-800Hz Lines When You Have a Choice?

Most people use 1000Hz as the standard setting, but nobody asks why. Why not make your life easier by having 1Hz resolution rather than 1.25 or 0.625 Hz? Lines is ALWAYS a selected value but FMax can be user defined or selectable.

Accelerometer mounting techniques impact the accuracy of vibration measurements

Guidance for vibration practitioners on evaluating and determining the ideal location and mounting method of vibration sensors for each machine and vibration source to be monitored. Specific guidance is given for permanent accelerometer installations, route-based data collection, high-frequency vibrations, low-clearance locations, and electrical isolation.
