Vibration Meters & Vibration Monitoring Systems
Vibration Monitoring and Testing - Select A Sub-Category For More Products
The decision to monitor the vibration of a piece of rotating machinery is based upon Return on Investment and is usually very easy to justify when considering the machine repair or replacement costs along with loss of production. Costs of Vibration Monitoring Equipment have decreased dramatically over the years. Accelerometers and other vibration transmitters can now be purchased for under $100.00, and complete sensor packages that connect to your computer for under $400.00. It also used to be that vibration testing was a very expensive preventative measure, but now you can purchase a Smart Vibration Meter for under $500.00. Today monitored rotating equipment includes pumps, motors, compressors, centrifuges, turbines, generators, gear boxes, fans, blowers, air handlers, chillers, and all other rotating machinery. Here you'll find all the tools needed to monitor, measure, and prevent excess vibration or bearing damage on your expensive machinery.

Two types of vibration sensors dominate the market today, Accelerometers and Proximity Probes. Accelerometers are used to measure the bearing cap vibration on rolling element bearings and Proximity Probes are used on Journal or Smooth Bore Bearings where the shaft is allowed to move within the bearing bore.
In essence Vibration sensors are mounted on the critical bearings and wired to the plant computer system or to a dedicated vibration monitoring system. Two alarm levels (Alert and Danger) are then set to alert the operator that maintenance attention is needed or in the case of Danger Alarm to shut the machine down to prevent failure. In some cases the Danger Alarm is wired to automatic machine shutdown.
In the case of expensive critical machinery multiple sensors may be used per bearing with each bearing of the machine train monitored. On less critical machines a single sensor may be used per bearing. On smaller motor driven equipment only the driven equipment may be monitored as the motor can inexpensively be replaced.
