Incorrect installation significantly impacts monitoring accuracy. Follow these guidelines to ensure reliable data.
Communication units placed too close together cause RF interference, degrading signal quality and reliability.
Placing units too high or too low prevents easy observation of Power & Signal Indicators.
Using too much adhesive or soft materials as fixing medium causes problems with vibration reading transference.
Rubber pads, foam tape, or flexible mounts absorb vibration energy and produce inaccurate sensor data.

Communication units placed too close together cause RF interference, degrading signal quality and reliability

Communication units in inaccessible positions (too high or too low) - to ensure Power & Signal Indicator can be observed easily

Prevent failure. Save money.
Component lifetime is increased by early warning of performance issues, avoiding catastrophic failure.
Motors, gearboxes & bearings replaced during planned downtime — not unplanned stoppages.
Taking an inefficient motor out of service delivers direct electricity savings and CO₂ reduction.
Overheating & vibration proven to reduce rotating component lifetime. Average motor life: 30,000 hours.
Motor insulation life is reduced by 50% when overheating and over-current conditions occur.
Direct contribution to customer sustainability and Net Zero targets through energy efficiency gains.
