Balanset-1A is a portable two-channel system for dynamic rotor balancing and simultaneous vibration analysis. The device allows you to balance rotors directly on-site (in their own bearings) without dismantling the equipment. Balanset-1A includes two vibration sensors (accelerometers), a laser rotation sensor (optical tachometer), and an interface unit that connects to a laptop via USB.

The key feature of the device is the ability to balance rotors directly in their own bearings at the operating site ("in-situ"), without the need to dismantle equipment. This drastically reduces downtime and labor costs. Additionally, Balanset-1A can be used as a modern measuring system to upgrade outdated balancing machines.

The specialized software automatically calculates imbalance and recommended correction weights for single- or two-plane balancing. Balanset-1A is easy to use and suitable even for specialists without deep knowledge in vibration diagnostics.

The Balanset-1A device was specifically designed with an emphasis on simplicity and accessibility, making it an ideal tool not only for experienced vibration diagnostics specialists but also for a wide range of technical workers:

• Maintenance and repair specialists: for quickly eliminating vibrations in industrial equipment
• Service engineers: for providing on-site balancing services
• Agro-industrial enterprise employees: for balancing rotors of combines, mulchers, shredders
• Ventilation system specialists: for balancing industrial fan impellers
• Special equipment operators: for servicing crushers, screens, and other rotating equipment

Thanks to high efficiency and affordable price, investment in the device typically pays off after performing just 2-3 balancing jobs.

Main specifications of Balanset-1A device:

These specifications provide high measurement accuracy and allow balancing rotors of various sizes and rotation speeds.

We offer two main configuration options:

You will only need your own laptop running Windows and correction weights for installation on the rotor during balancing.

Almost any modern laptop or PC with Windows 7 / 8 / 10 / 11 will work. Main requirements:

• Operating system: Windows 7, 8, 10, or 11 (32-bit and 64-bit supported)
• USB port: At least one free USB 2.0 port or higher

The device connects via USB, which serves for both data transfer and device power. No special requirements for laptop specifications.

The software supports multiple interface languages: Russian, English, German, French, Polish and others. You can select the desired language during installation or in the program settings.

Yes, Balanset-1A performs vibrometer functions in addition to balancing. The device can analyze vibrations up to 1000 Hz when used with tachometer. In "Vibrometer" mode (F5 key), you can view:

• V1s, V2s: Overall vibration level (RMS) in planes 1 and 2
• V1o, V2o: Rotational vibration component (1x frequency)
• Spectrum (FFT): Vibration distribution by frequency

Balanset-1A is universal and suitable for virtually any rotating rotors:

• Industrial fans and smoke exhausters
• Crushers (hammer, rotor, etc.)
• Mulchers and shredders
• Augers and rotors of agricultural machinery
• Cardan shafts and long drives
• Centrifuges and separators
• Turbines and compressors
• Grinding wheels and machine spindles
• Pumps and impellers
• Pulleys and flywheels
• Electric motor and generator rotors
• Propellers and air screws

Yes, Balanset-1A can be used as a measuring system for a balancing machine. If you have a stationary balancing stand with outdated electronics, you can install Balanset sensors on its supports and "digitize" the machine, getting modern balancing functionality without purchasing an expensive new stand.

1. Insert the USB drive from the delivery kit into your computer
2. Run the installation file and follow the on-screen instructions
3. After installation, connect the Balanset-1A interface unit via USB - the system will automatically recognize the device
4. Launch the program using the desktop shortcut

Connecting cables: Connect two vibration sensors to connectors X1 and X2, and the laser tachometer to connector X3.

Installing vibration sensors: Mount sensors on fixed parts of the mechanism housing, as close as possible to the bearing supports. Use magnets or threaded studs for rigid installation.

Installing the tachometer: Mount the laser tachometer on a magnetic stand, position it 50-500 mm from the rotor shaft. Apply reflective tape to the shaft. Ensure the laser beam has direct visibility to the mark.

Up to 80% of balancing success depends on thorough preparation. Before starting:

• Rotor cleanliness: Clean the rotor from dirt, rust, adhered product
• Bearing condition: Check for excessive play, foreign noises, overheating
• Foundation rigidity: Ensure the unit is securely mounted, all anchor bolts tightened
• No rubbing: Check that the rotating rotor doesn't rub against stationary parts

The device uses the classic influence method (three-run method):

1. Run #0 (Initial): Start the mechanism at operating speed. Press the button to measure initial vibration level.
2. Run #1 (Trial weight plane 1): Stop mechanism. Install trial weight in plane 1. Start and measure. Stop and remove trial weight.
3. Run #2 (Trial weight plane 2): Install same trial weight in plane 2. Start and measure. Stop and remove trial weight.
4. Calculation: Software calculates mass and angle for correction weights in both planes.
5. Verification (RunC): Install calculated correction weights. Run and verify vibration reduction.

The trial weight should cause a significant change in vibration parameters:

• Vibration amplitude changes by at least 20-30%
• OR phase angle changes by at least 20-30 degrees

If readings barely change, use a heavier weight. The manual provides a formula for approximate calculation.

1. Sensor installation: Mount two vibration sensors perpendicular to the rotation axis near bearings. Attach reflective tape to shaft for tachometer.
2. Connection: Connect sensors to Balanset-1A, connect unit to laptop, launch software.
3. Initial measurement: Select two-plane balancing mode. Start rotor at operating speed, press "Measure #0".
4. Trial weight runs: Stop rotor, attach trial weight to Plane 1, measure. Move weight to Plane 2, measure. Remove weight.
5. Calculation: Software calculates masses and angles for permanent correction weights.
6. Verification: Install correction weights, run rotor, verify vibration is within acceptable limits.
7. Save results: Save influence coefficients for future use on similar rotors.

No, in most cases there is no need to remove the rotor. Balanset-1A is designed for in-situ balancing - you perform all measurements directly on installed equipment without dismantling. This saves significant time and effort.

"Influence coefficients" are a digital "fingerprint" of how a specific rotor type responds to trial weight installation. After the first successful balancing, you can save these coefficients.

For subsequent balancing of the same rotor type, load the saved coefficients - the program will calculate corrections immediately after the first run, skipping trial weight stages. This saves up to 50% of time on each subsequent unit.

• Saving: After balancing, save all data to the archive with a unique name
• Report generation: In main menu (F6), select record and generate detailed report
• Printing: Send report directly to printer with all necessary information

• Grinding wheel balancing: Special mode using three-counterweight method
• Weight splitting: Automatically split required mass between two adjacent positions
• Drilling calculation: Calculate required diameter and depth for mass removal
• Mandrel eccentricity exclusion: Index balancing mode for high-precision work

• Foreign materials inside rotor: Water, dirt, or loose material causes changing imbalance. Clean and dry the rotor.
• Structural resonance: Change rotation speed to exit resonance zone.
• Adjacent mechanisms: Nearby machines may introduce interference. Temporarily shut them down.
• Mechanical defects: Cracks, damaged bearings, loose bolts cause variable vibration. Repair first.
• Rotor contact: Check clearances - rotor shouldn't rub against stationary parts.

• Check angle: Ensure you're counting the angle in the direction of rotation from the correct reference.
• Verify stability: Check if any fasteners loosened or resonance appeared.
• Reduce weight: Try using a weight 1.5-3 times lighter than calculated.
• Repeat cycle: Remove weight and repeat measurements, possibly with different trial weights.

• Distance: Optimal distance is 50-500 mm (5-50 cm). Adjust as needed.
• Beam angle: Laser should hit the mark perpendicular to surface.
• Obstacles: Ensure nothing blocks the laser beam.
• Mark quality: Use clear, contrasting reflective tape ~1-2 cm wide.
• Lighting: Shade the sensor from bright sunlight if working outdoors.

• Structural resonance: Move system out of resonance by changing rotation frequency.
• Faulty bearings: Replace worn or damaged bearings first.
• Shaft misalignment: Perform alignment before balancing.
• Loose mounting: Check and tighten all bolted connections.
• Rotor contact: Ensure adequate clearance between rotating and stationary parts.

Remember: balancing doesn't replace repair of faulty equipment.

Misalignment creates a characteristic vibration pattern. In "Vibrometer" mode, look at the spectrum (FFT). With misalignment, besides the peak at rotation frequency (1x), you'll see significant peaks at frequencies twice and three times the rotational (so-called 2nd and 3rd harmonics). If these peaks are comparable in height to the main one, this is a sure sign of misalignment that needs to be eliminated before balancing.

Any friction or contact of the rotor with the stator causes strong chaotic vibration and makes balancing impossible. This must be eliminated first. Check and ensure adequate clearances between all rotating and stationary parts.

If there seems to be a signal but the software reports tachometer error or rotation irregularity, there can be several reasons:

• Unstable rotor rotation speed: The program monitors rotation uniformity during measurement; if RPM floats (e.g., motor cannot maintain constant speed, or rotor is braked by load), phase measurements may be erroneous. In the software settings there is a "Irregularity" parameter - increase the allowable rotation irregularity value so the program is less sensitive to small speed fluctuations.
• False tachometer triggers: Sometimes the laser sensor can pick up reflections from other parts of the rotor (e.g., from a polished surface near the mark), causing it to register extra pulses. As a result, the program sees multiple marks and gets confused. Solution - change position or orient the sensor at a different angle so it "sees" only your reflective mark and doesn't catch parasitic reflections.
• Sensor displacement during measurement: Ensure nobody moved the tachometer stand during measurement. It happens that vibration or careless movement changed the beam direction - and it stopped "seeing" the mark correctly, although initially it was reading. Therefore, always rigidly fix the tachometer and don't touch it until all measurements are complete.

Overall, tachometer error means the program couldn't correctly link vibration phase to revolutions. You need to achieve a clear single pulse per revolution and stabilize rotation frequency - then this error will disappear and phase measurements will be reliable.
