Vibration monitors suitable for ATEX zones

05 January 2009

FM Electronic is offering the Efector Octavis bearing vibration monitors in designs suitable for ATEX zones. The VE111A and VE112A versions are suitable for Zone 2 and 22. Zone 1 and 21 approval has been granted to the VE113A.The Efector Octavis detects rolling element bearing failures and shaft imbalance conditions.

It can analyse a vibration signature and predict failures in advance by sending an alarm output signal to a PLC or relay. The monitor incorporates an accelerometer, analogue-to-digital converter, digital signal processor and diagnostic electronics in a compact 40 x 40mm package. These electronic components enable the monitor to gather, process and interpret vibration data.

Configuration software is used on setup to input application parameters such as bearing types, shaft speed and output conditions via an R485 cable.

These parameters allow the Efector Octavis to monitor only critical damage frequencies in the vibration spectrum and ignore all external noise.

One Efector Octavis monitor can detect up to five different rolling elements on a machine or 20 individual frequencies.
