Portable vibration meter Balanset-1A

with touch screenfor balancingfor rotors

Balanset-1A is a portable balancer and dual-channel vibration analyzer for field balancing of mulcher and flail mower rotors, straw choppers, augers, fans and mills in one or two planes.
Works with your Windows laptop via USB — laptop not included (Windows 7/8/10/11, 32- or 64-bit, one free USB port). The rotor stays in its own bearings: no dismantling.
Uneven wear, lost flails and weld repairs can shift rotor balance.
Agricultural applications

• Mulcher and flail mower rotors, including forestry mulchers
• Combine straw choppers and threshing drums
• Augers
• Grain-dryer and ventilation fans
• Hammer and feed mills
• Forage-harvester cutterheads
• Pumps and motors on the farm

Key specifications

• Channels: 2 vibration + 1 speed · Correction planes: 1 or 2
• Rotor speed: 100–100,000 rpm
• Vibration range: 0.02–80 mm/s RMS
• Frequency range: 5–1000 Hz (balancing and FFT); amplitude error ≤10 % at 5–550 Hz, up to 20 % at 550–1000 Hz
• Phase accuracy: ±1° · RMS velocity accuracy: ±(0.1 mm/s + 10 %)
• Overall accuracy: 5 % of full scale
• Sensor cable: 5 m (10 m option) · Power: USB 5 V DC · IP54 · Weight: 4 kg (complete kit)
• Standards: ISO 21940-11 (balancing), ISO 20816 (vibration evaluation)

Full Kit includes

• Balanset-1A USB interface unit
• 2 vibration sensors
• Optical laser tachometer and reflective tape
• Windows balancing software on a USB drive
• Magnetic stand, digital scale and plastic transportation case

Have a stand, scale and case? Balanset-1A OEM has the same unit and software without them.
How it works

• 1. Setup: sensors on the bearing housings, reflective tape on the rotor, laser tachometer aimed at the tape.
• 2. Initial run: the software records baseline 1× amplitude and phase.
• 3. Trial-weight runs in plane 1, then plane 2; the software calculates the influence coefficients.
• 4. Correction: weld or bolt the calculated weights at the given angles, then check residual vibration against the ISO 21940-11 tolerance.

Typical time: 20–40 minutes per rotor. The software also has a vibrometer mode with FFT spectrum, a polar graph, saved coefficients for repeat balancing, reports and an archive.
Not sure it fits? Send the machine type, rotor speed and a photo of the bearing housings for a suitability check.
