Description
Balanset-1A is a portable, USB-powered vibration analyzer and balancer for one- and two-plane balancing of rotors in their own bearings. The Full Kit includes the interface unit, two vibration sensors, optical laser tachometer, reflective tape, Windows balancing software on a USB drive, magnetic stand, digital scale and transport case. Requires a compatible Windows computer with a free USB port; computer not included. The sensors and software measure vibration and calculate correction mass and angle from trial-weight runs.

How field balancing works
Single-plane or two-plane dynamic balancing, on-site, without disassembly. Typical workflow: 20–40 minutes per rotor.
-
Step 1Setup
Mount vibration sensors on the bearing housings, stick reflective tape on the shaft, connect the laser tachometer and the USB unit to your laptop.
-
Step 2Initial run (Run #0)
Spin up the rotor and let the speed stabilise. The software records baseline 1× amplitude and phase in both planes — this is the starting imbalance.
-
Step 3Trial weight runs (Run #1 & Run #2)
Attach a known trial weight in plane 1, run the rotor, record the new vibration. Stop, move the trial weight to plane 2, run again. From these two responses the software computes how the rotor reacts to added mass in each plane — the influence coefficients.
-
Step 4Apply correction & verify
Remove the trial weights. The software outputs the exact mass and angular position of the final balance weights for each plane. Bolt or weld them in place, run the rotor again, and check that the residual vibration is within ISO 21940-11 tolerance. Add a small fine correction if needed.
Why bother with trial weights at all?
Without a trial weight the device only sees that there is vibration. It can't know:
- how much corrective mass is needed,
- where exactly on the rotor it has to sit,
- how the rotor & supports respond to mass added in each plane.
The trial weight introduces a known change of imbalance. By comparing vibration before and after, the software calculates the influence coefficients — and from those, the exact mass and angle of the final balance weight. No guessing, no iterative trial-and-error.

Safety information and warnings
- Class 2 laser product. The phase sensor emits a visible laser beam. Do not stare into the beam and do not point it at people.
- Electrical safety. Observe electrical safety regulations when working on 220 V equipment. Never repair the device while it is connected to 220 V.
- Machine lockout. Always apply lockout/tagout procedures before installing sensors.
- Protective equipment. Wear safety glasses and hearing protection, and avoid loose clothing near rotating machinery.
- Secure installation. Make sure all sensors and cables are fastened and cannot be caught by rotating parts.
- Trained personnel only. Know the location of emergency stops and the shutdown procedure before starting work.
