HVAC and other rotating equipment often emit vibratory forces that can often be used to diagnose machinery health. This information can be used to create a maintenance plan to avoid premature failure and downtime. The WVS-1000 data acquisition device (DAQ) connects wirelessly to smart devices with Apple® iOS® 10.3 operating system and above. Using the Johnson Controls® Vibration Diagnostics Service mobile app, the user can collect vibration data that uses a tri-axial vibration sensor and expedites the data collection process. The data is then uploaded from the smart device to the cloud. The data is analyzed by certified vibration analysts and a customer report is generated and sent via email.
