A Petrobras anunciou nesta segunda-feira (5) que vai aumentar os preços da gasolina, do diesel e do gás de cozinha (GLP) a partir desta terça-feira (6). Segundo a estatal, os reajustes acompanham a elevação nos patamares internacionais de preços de petróleo e derivados.
Para a gasolina, o aumento médio será de R$ 0,16 (6,3%), fazendo com que o litro do combustível saia de R$ 2,53 e chegue a R$ 2,69 nas refinarias da estatal.
Já o diesel terá um reajuste médio de R$ 0,10 (3,7%) por litro, que passará custar R$ 2,81 nas refinarias da Petrobras.
A estatal anunciou ainda que o preço médio de venda do GLP para as distribuidoras passará a ser de R$ 3,60 por kg, refletindo um aumento médio de R$ 0,20 por kg.

Balanset-1A: Innovative Compact Balancer & Vibration Analyzer
High-precision Dynamic Balancing Solution
Balanset-1A serves as an revolutionary solution for dynamic balancing of rotors in their own bearings, created by Estonian company Vibromera OU. The device ensures professional equipment balancing at €1,751, which is substantially less expensive than traditional vibration analyzers while preserving exceptional measurement accuracy. The system allows field balancing directly at the equipment’s operational location without necessitating dismantling, which is critically important for reducing production downtime.
About the Manufacturer
Vibromera OU is an Estonian company concentrating in the development and manufacturing of instruments for technical diagnostics of industrial equipment. The company is established in Estonia (registration number 14317077) and has branches in Portugal.

Technical Specifications
Measurement Parameters
Balanset-1A ensures high-precision 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 rotational speed measurement from 250 to 90,000 RPM with phase angle determination accuracy of ±1 degree.
Working Principle
The device utilizes phase-sensitive vibration measurement technology with MEMS accelerometers ADXL335 and laser tachometry. Two mono-directional accelerometers measure mechanical vibrations proportional to acceleration, while a laser tachometer generates pulse signals for calculating rotational speed and phase angle. Digital signal processing includes FFT analysis for frequency analysis and specialized algorithms for automatic computation of corrective masses.
Full Kit Components
The standard Balanset-1A delivery includes:
Measurement unit with USB interface – main module with embedded 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 operates as a full-featured vibration analyzer with features for measuring overall vibration level, FFT spectrum analysis up to 1000 Hz, calculating amplitude and phase of the fundamental frequency (1x), and continuous data recording. The system provides visualization of time signals and spectral analysis for equipment condition diagnostics.
Balancing Mode
The device supports one-plane (static) and dual-plane (dynamic) balancing with automatic calculation of corrective masses and their installation angles. The unique influence coefficient saving function permits considerable acceleration of repeat balancing of same-type equipment. A dedicated grinding wheel balancing mode uses the three-correction-weight method.
Software
The easy-to-use program interface provides step-by-step guidance through the balancing process, making the device accessible to personnel without specialized 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 successfully 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 special value for agriculture, where uninterrupted operation during season is critically important. Balanset-1A is applied for balancing combine threshing drums, shredders, mulchers, mowers, and augers. The ability to balance on-site without equipment disassembly permits eliminating costly downtime during critical harvest periods.
Specialized Equipment
The device is effectively 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 virtually all types of industrial equipment.
Advantages Over Similar Products
Economic Effectiveness
At a price of €1,751, Balanset-1A provides the functionality of devices costing €10,000-25,000. The investment pays for itself after preventing just 2-3 bearing failures. Cost reduction on external balancing specialist services reaches thousands of euros annually.
Ease of Use
Unlike sophisticated vibration analyzers requiring months of training, mastering Balanset-1A takes 3-4 hours. The step-by-step guide in the software permits professional balancing by personnel without special vibration diagnostics training.
Mobility and Autonomy
The complete kit weighs only 4 kg, with power supplied through the laptop’s USB port. This allows balancing in field conditions, at isolated sites, and in inaccessible locations without external power supply.
Versatile Application
One device is appropriate for balancing the broadest spectrum of equipment – from small electric motors to large industrial fans and turbines. Support for one and dual-plane balancing covers all common 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 exceptional accuracy of the device even on small rotors.
Shopping Center Ventilation Systems
Engineers successfully balanced radial fans, achieving lower energy consumption, eliminated excessive noise, and increased equipment lifespan. Energy savings paid for the device cost within several months.
Agricultural Equipment
Farmers note that Balanset-1A has become an indispensable tool preventing costly breakdowns during peak season. Decreased vibration of threshing drums led to reduced fuel consumption and bearing wear.
