Technical Insight
Why is vibration monitoring critical for pumps?Pump cavitation creates high-frequency micro-jets that pit the impeller surface. Our sensors are tuned to pick up these specific frequency changes long before a technician can hear the noise. By monitoring the RMS Velocity, our vibration sensors provide a clear picture of the overall machine health, aligned with ISO 10816-3 standards for industrial pumps.
FAQ Section
Where is the best mounting point on a pump?
A: Always mount the sensor on the bearing housing in the radial direction for the best sensitivity to unbalance and bearing faults.
Can this sensor work underwater?
A: Yes, the KH-Series features an integrated cable and IP68 sealing, allowing for continuous operation in submerged applications.
