How to Get Repeatable Readings
Repeatability is crucial to route-based data collection to ensure accurate and consistent results. The importance of repeatability in vibration testing is two-fold. First, it allows technicians to compare data across different testing cycles. This is important for identifying any changes in performance or possible trends that may indicate an impending problem. Second, it allows technicians to track the performance of the equipment or component over time, and to determine whether it is suitable for its intended purpose.
There are several ways to enhance repeatable test points. First, technicians should strive to use the same equipment and settings for all tests. This will reduce the risk of variance in results due to differences in equipment or settings.
Second, technicians should ensure that all test points are accurately documented and documented consistently. This will ensure that all data is properly collected and analyzed.
Third, technicians utilize vibration test points and/or quick disconnect receptacles to ensure that data is collected from the same location every single time. Vibration test points are magnetically attractive adhesive mounting pads. Simply attach the vibration test point to the machine using epoxy and let cure. This is a cost-effective and easy way to create a flat and consistent landing pad for an analyst to attach a magnet-mounted accelerometer on the same spot of the machine each and every time.
MH133-1A Low Profile Vibration Test Point
CTC's quick disconnects are ideally suited for triaxial sensor use. The permanently-mounted stud creates a consistent mounting location for portable routes. The receptacle features a triaxial locating notch and ¼-turn engagement onto the stud, ensuring the sensor is oriented in the same position for every reading
