Product Introduction

One shot locate heavy spot of imbalance without stopping the machine

S911HD is a small sized economical vibration Spectrum analyzer & data collector. It can be used for overall vibration measurement, Spectrum analysis. Measurement of high frequency acceleration envelope makes it very effective for bearing fault detection. The data can be sent to computer for database and trending analysis.

It is also a low-cost, easy-to-use 1 plane rotor balancer with the measurement of Rotation speed RPM, Amplitude & Phase. It can one-shot locate the heavy spot of unbalanced rotors (without stopping the machine, without adding trial mass, by a laser tacho sensor and an accelerometer). This one-shot method does not estimate the correction weight which in most of the case can be estimated and fine-tuning by experience or by standard influence-coefficients-based calculator. Even though, this still makes the balancing process very easy and quick, so can save cost and time.
