Message from Us

(1) We are specialized manufacturer of accelerometers and vibration sensors with 30 years of history. For over 30 years, we have been engaged in design, development and manufacture of vibration meters and accelerometers. Since establishment, we have had it as our philosophy that we make vibration meters that are easy to use, easy to understand and reliable. We deal with not only vibration meters, but also designing and manufacturing of meters that have an analog circuit in it, which requires know-how accumulated for a long time. Long period of experience is needed to design an analog circuit and choose the right components. The digitalization of meters is an inevitable tendency, but sensor signal is very small sensitive analog data. Before doing digitalize measured signals of an analog sensor or processing signals, you need to make a signal adjustment at the analog front end, in terms of low noise and high stability of temperature, which will make the whole measurement system highly precise. We are knowledgeable about this delicate signal and have developed a lot of customized and specialized analog circuits, so we believe you will be satisfied with our efficiency and cost. If you have any problem with your analog circuit of a meter or a signal adjuster, please contact us.

(2) Consult us on control software and analysis application

We have been tackling new measurement systems using new technology such as development of LabVIEW software, microcontroller etc. We are trying hard to make real time analysis and signal processing easier and more efficient. We use the standard of measurement software, LabVIEW from National Instruments Corporation, for measurement control and analysis application software. It enables data analysis or data acquisition that the conventional meters cannot handle–such as simultaneous measurement of several sensors, simultaneous vibration frequency analysis and saving synchronized data. In our company, certified LabVIEW developers are in charge of designing and development. By designing and developing important software application in-house, we provide you easy-to-use, highly functional products and are always ready for customization. We have been building measurement systems that are highly usable, functional and cost efficiency, by combining our three developing technologies: Developing technology of measurement analysis software application by using LabVIEW, developing technology of highly functional embedded firmware and designing technology of an analog circuit at the analog front end (signal adjusting part) that plays an important part in high precision measurement. We adjust everything in-house from sensor specifications to user interface, and realize great cost performance as well as high functionality and usability. By making the development period short and cutting down the cost, we are making measurement systems that satisfy customers.
