The Efector Octavis is a compact diagnosis system, which evaluates vibration signals by use of frequency analysis. The system makes use of a micromechanical acceleration sensor, and data can be collected, processed and evaluated decentrally, with no expert knowledge required to make sense of the findings.

The unit has been designed for continuous monitoring, so that it can detect early onset of rolling element bearing damage and unbalance. Compared to intermittent methods of monitoring, the Efector Octavis offers both a reliable and cost-effective solution.

The Efector Octavis is capable of performing a lot of automated analysis for you. For example, acoustic emission is automatically detected, the frequency spectrum is calculated and both the rolling element bearing state and unbalance are evaluated.

Status and condition of the bearing can be read directly on-site, and is also signalled via binary switching outputs. The switching signal can be transmitted via unscreened cables, and it is also possible to connect the unit up to bus systems.

The unit itself is very user-friendly to operate. Basic parameters (such as the type of bearing, rotation speed, etc) can easily be configured via an RS-232 cable and use of a PC (connecting via USB). Reference condition of the machine is taught-in after mounting, simply by pressing a button on the sensor itself.

Damage to rolling element bearings is automatically detected by the unit when it arises. The bearing monitor then sets switching output, and indicates an early warning with a yellow LED. The operator is then table to take preventive action. Progrssive damage of the bearing is then signaled via a second switching output and use of a red LED. The operator should then use this alert to react immediately.

Operating status: Normal	Early warning alarm: Arising damage	Criticial alarm: Advanced damage

Critical plant equipment, such as pumps and motors, compressors, fans and spindles, can all be monitored by using vibration analysis and a product such as the Efector Octavis.

For bearings, typical causes of failure include: wear, misalignment and over-lubrication. The Efector Octavis monitors the inner race, outer race and rolling elements of a bearing. So as to monitor the critical frequencies, the unit needs to collect the following data from the bearing:

• Metric data, such as...
• Number of rolling elements
• Rolling element diameter
• Pitch diameter or DIN number
• Rotational speed (RPM)

For shift unbalance applications, the Efector Octavis reliably detects unbalance at an early stages. This form of condition diagnosis allows predictive action to be taken early, preventing costly damage and downtime. For the unit to monitor unbalance, the rotational speed of the bearing is required, and this is set as one of the parameters.

Some of the features of the Efector Octavis include...

• Compact design includes sensor and diagnostic capabilities in the one unit
• Prevent unplanned downtime by detecting damage of rolling element bearings and unbalance
• Help ensure optimum uptime of machines due to permanent monitoring
• Outputs data to external systems for further analysis
• Uses easy-to-understand colour system for alerting operator to status
