How fast is the data collection speed of your vibration data collector? You may feel that this is not an important characteristic. Does it really matter if a data collector is one or two seconds faster-acquiring data versus another? Data collection speed is very important and should be taken into consideration by your facility management and Condition Monitoring Group. For example, consider a vibration monitoring program that monitors 1000 machine trains per month with 10 measurement points per machine train. If a vibration data collector requires 8 seconds to acquire data for each measurement point, then it would necessitate 22 hours of real data collection time (this does not include time moving between each machine, reporting time or etc). Does a second really make a difference? A data collector that is one second faster acquiring the same data will result in 3 hours per month saved or almost one full man week per year. If the data collector is 3 seconds faster in acquiring the same data, then the time savings are more substantial. A savings of 3 seconds per measurement point will result in a savings of 2.5 man-weeks per year. Multiply the time savings by your labor cost per hour and the savings could be very important to your facility. The savings may surprise you!
