We will exhibit at the Japan Society of Earthquake Engineering Conference - 2024 (December 4-5).

Seismic measurement is possible in extreme environments such as places where power cannot be supplied, environments where electronic components do not operate, and plant equipment with explosion-proof requirements!

The "Optical Sensor Seismometer System" enables high-precision seismic measurements in extreme environments where conventional equipment cannot operate, such as locations without power supply, environments where electronic components do not function, and plant facilities with explosion-proof requirements. 【Features】 ■ No power supply or electronic components required (from fiber optic cable to sensor unit) ■ High temperature, high pressure, lightning resistance, explosion-proof, and radiation resistance ■ Capable of long-distance and wide-area observation ■ Long-term stable operation in the field ■ Reduced construction time and cost *For more details, please check the related links below or contact us.

• Other measurement, recording and measuring instruments
• Vibration Inspection

Compact, lightweight, and low power consumption telemeters packed with multifunctionality!

The "LT-7700" maintains the low power consumption of the "7000 series" while achieving multifunctionality with DATAMARK's telemetry. It enables new observation styles even in environments where temporary observations of earthquakes and volcanic eruptions are needed, or where commercial power sources are unavailable. Compatibility with different conventional products in terms of sampling timing and frequency characteristics can be achieved. 【Features】 ■ High functionality and low power consumption ■ Compatibility mode with conventional products ■ All 6 channels × high-speed sampling ■ Redundancy in data centers *For more details, please refer to the PDF document or feel free to contact us.

• Other measurement, recording and measuring instruments

Easy mobile observation! Observations that require mobility outdoors can be conducted smoothly.

The JU410 is a micro-motion observation device that incorporates a servo accelerometer, AD device, GPS receiver function, wireless LAN communication function, and battery within its housing. It features a portable, integrated housing that is suitable for observations requiring mobility. Additionally, it can be customized for long-term observations by connecting external batteries and external sensors. 【Features】 ■ Uses a servo accelerometer ■ Compact integrated housing ■ Operates solely on the built-in battery ■ Data transmission via wireless LAN ■ Small and lightweight at 2.98 kg ■ Ideal for outdoor mobile observations *For more details, please refer to the PDF materials or feel free to contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
