Measurement & Monitoring Continuous machine protection Easy condition monitoring from ifm electronic I t is now easy and costeffective to monitor vibration on more moving parts with the latest efector octavis product from sensor market leader ifm electronic Ltd. The efector octavis VKV is a selfcontained vibration monitor with built-in switching output along with a transmitter function. Attached to almost any machine the VKV monitors the overall condition of equipment by analysing the severity of the vibration. ISO Standards For Evaluation Of Vibration Severity Knowing how to set up such a unit is made easier by reference to the ISO standard 10816. This standard establishes the general conditions and procedures for the measurement and evaluation of vibration, using measurements made on the nonrotating parts of machines, primarily with regard to securing reliable long- term operation. Coverage of machine types in the Standard ranges from reciprocating pumps, via industrial machines to steam turbines and generators. Mechanical vibration is the key; evaluation of machine vibration by measurements on non-rotating parts. The efector octavis VKV is firmly attached to the machine, then the rms (vibration in mm/sec or even inches/ sec) is set on the first ring followed by the time delay on the second. Once the setting is in and locked, the job is done and the VKV will keep an eye on that plant 24/7. Small and easily set-up, the efector octavis VKV reduces the need for specialist knowledge or expensive outsourcing. The output will switch if the pre-set vibration velocity is reached, or the additional 4-20mA signal is there to display a value or be centrally monitored.
