    Balanset-1A: Cutting-edge Compact Balancer & Vibration Analyzer Next-generation Dynamic Balancing Solution Balanset-1A serves as an innovative solution for dynamic balancing of rotors in their own bearings, manufactured by Estonian company Vibromera OU. The device ensures professional equipment balancing at €1,751, which is significantly cheaper than traditional vibration analyzers while preserving high measurement accuracy. The system enables in-place balancing directly at the equipment's working position without requiring removal, which is essential for preventing production downtime. About the Manufacturer Vibromera OU is an Estonian company focusing in the creation and manufacturing of devices for technical diagnostics of industrial equipment. The company is incorporated in Estonia (registration number 14317077) and has offices in Portugal. Contact Information: Official website: https://vibromera.eu/shop/2/ Technical Specifications Measurement Parameters Balanset-1A provides precise measurements using a dual-channel vibration analysis system. The device measures RMS vibration velocity in the range of 0-80 mm/s with an accuracy of ±(0.1 + 0.1?Vi) mm/s. The working frequency range is 5-550 Hz with potential extension to 1000 Hz. The system supports RPM measurement from 250 to 90,000 RPM with phase angle determination accuracy of ±1 degree. Operating Principle The device employs phase-sensitive vibration measurement technology with MEMS accelerometers ADXL335 and laser tachometry. Two uniaxial accelerometers measure mechanical vibrations proportional to acceleration, while a laser tachometer generates impulse signals for computing RPM and phase angle. Digital signal processing includes FFT analysis for frequency analysis and custom algorithms for automatic computation of correction masses. Full Kit Package The standard Balanset-1A delivery includes: Measurement unit with USB interface - central module with integrated preamplifiers, integrators, and ADC 2 vibration sensors (accelerometers) with 4m cables (optionally 10m) Optical sensor (laser tachometer) with 50-500mm measuring distance Magnetic stand for sensor mounting Electronic scales for accurate measurement of corrective masses Software for Windows 7-11 (32/64-bit) Plastic transport case Complete set of cables and documentation Functional Capabilities Vibrometer Mode Balanset-1A works as a complete vibration analyzer with capabilities for measuring overall vibration level, FFT spectrum analysis up to 1000 Hz, measuring amplitude and phase of the fundamental frequency (1x), and continuous data recording. The system delivers display of time signals and spectral analysis for equipment condition diagnostics. Balancing Mode The device supports single-plane (static) and dual-plane (dynamic) balancing with automatic calculation of correction masses and their installation angles. The unique influence coefficient saving function allows substantial acceleration of subsequent balancing of identical equipment. A dedicated grinding wheel balancing mode uses the three-correction-weight method. Software The intuitive program interface offers step-by-step guidance through the balancing process, making the device accessible to personnel without specific training. Key functions include: Automatic tolerance calculation per ISO 1940 Polar diagrams for imbalance visualization Result archiving with report generation capability Metric and imperial system support Multilingual interface (English, German, French, Polish, Russian) Fields of Use and Equipment Types Industrial Equipment Balanset-1A is effectively applied for balancing fans (centrifugal, axial), pumps (hydraulic, centrifugal), turbines (steam, gas), centrifuges, compressors, and electric motors. In production facilities, the device is used for balancing grinding wheels, machine spindles, and drive shafts. Agricultural Machinery The device represents exceptional value for agriculture, where uninterrupted operation during season is essential. Balanset-1A is used for balancing combine threshing drums, shredders, mulchers, mowers, and augers. The ability to balance on-site without equipment disassembly allows preventing costly downtime during critical harvest periods. Specialized Equipment The device is successfully used for balancing crushers of various types, turbochargers, drone propellers, and other high-speed equipment. The RPM frequency range from 250 to 90,000 RPM covers essentially all types of industrial equipment. Benefits Over Competitors Economic Efficiency At a price of €1,751, Balanset-1A offers the functionality of devices costing €10,000-25,000. The investment breaks even after preventing just 2-3 bearing failures. Savings on outsourced balancing specialist services totals thousands of euros annually. Ease of Use Unlike complicated vibration analyzers requiring months of training, mastering Balanset-1A takes 3-4 hours. The step-by-step guide in the software allows professional balancing by personnel without specific vibration diagnostics training. Mobility and Independence The complete kit weighs only 4 kg, with power supplied through the laptop's USB port. This allows balancing in outdoor conditions, at remote sites, and in hard-to-reach locations without additional power supply. Versatile Application One device is suitable for balancing the most extensive spectrum of equipment - from small electric motors to large industrial fans and turbines. Support for single and dual-plane balancing covers all typical tasks. Real Application Results Drone Propeller Balancing A user achieved vibration reduction from 0.74 mm/s to 0.014 mm/s - a 50-fold improvement. This demonstrates the remarkable accuracy of the device even on small rotors. Shopping Center Ventilation Systems Engineers effectively balanced radial fans, achieving lower energy consumption, removed excessive noise, and extended equipment lifespan. Energy savings paid for the device cost within several months. Agricultural Equipment Farmers note that Balanset-1A has become an vital tool preventing costly breakdowns during peak season. Reduced vibration of threshing drums led to reduced fuel consumption and bearing wear. Cost and Delivery Terms Current Prices Complete Balanset-1A Kit: €1,751 OEM Kit (without case, stand, and scales): €1,561 Special Offer: €50 discount for newsletter subscribers Volume Discounts: up to 15% for orders of 4+ units Acquisition Options Official Website: vibromera.eu (recommended) eBay: certified sellers with 100% rating Industrial Distributors: through B2B channels Payment and Shipping Terms Payment Methods: PayPal, bank cards, bank transfer Shipping: 10-20 business days by international mail Shipping Cost: from $10 (economy) to $95 (express) Warranty: factory warranty Technical Support: included in price Final Assessment Balanset-1A constitutes an perfect solution for organizations striving to implement an successful equipment balancing system without substantial capital expenditure. The device makes accessible access to professional balancing, permitting small businesses and service centers to offer services at the level of large industrial companies. The blend of affordable price, ease of use, and professional features makes Balanset-1A an indispensable tool for modern technical maintenance. Investment in this device is an investment in equipment dependability, lower operating costs, and increased competitiveness of your enterprise.
