A longtime dream, a slip-ring-less rotating torque meter, UTMⅡ , has just become available. We developed it as a high performance sensor for embedded applications. Of course, it is also perfect for general dynamic torque measurement. This is our masterpiece, which has 1/10000-resolution, outstanding zero-point stability and 1kHz-bandwidth (sampling frequency of 6kHz). UNIPULSE was established by several young engineers in 1970 and has specialized in industrial measurement since that time. We have developed a lot of unique products and expanded our own market. Though we had wished to make a...
^ High response speed with cut-off frequency of 1kHz (sampling frequency of 6kHz). This series can be used for not only fast process monitoring but also torque feedback control. J Safe overload of 500%. 1, 2 and 5-line capacities are standardized from 0.05Nm to 10000Nm. ^ A rotational pulse generating circuit (4 pulses/revolution) is built in as standard. Lower rotational speed can be measured accurately. ^ Improved noise immunity with insulated powering and signaling system. Features of UTMI - Line-up J 1/10000 resolution. | Outstanding zero-point stability. | Max. rotational speed: 25,000...
Overview Principle of UTMⅡ UTMⅡ adopts strain gauges for detecting torsional strain, which is converted into an electric signal by a strain amplifier fixed on the rotating shaft. Electric power for the rotary electronics is supplied continuously through a wireless power system originally developed by UNIPULSE. The detected torque signal is converted into a digital signal, and it is transmitted to the main-frame electronics via a light signal. The rotating shaft is suspended with only two small bearings, resulting in very low rotational friction. Compact and easy to install High accuracy and...
