• Other measurement, recording and measuring instruments

For temperature monitoring of transformers, reliable temperature monitoring is possible without being affected by noise from EMI/RFI and high voltage environments.

OSENSA's fiber optic temperature sensor for transformers enables real-time temperature monitoring of transformers without being affected by noise in environments with EMI/RFI or high voltage. The basic configuration of this product consists of a temperature sensor probe, a transmitter, and software. The probe PRB-230 is designed for temperature measurement in oil-filled transformers and accommodates immersion and removal processes for various types of transformer oil. The transmitter is available in a type that can connect multiple probes with a single unit, allowing for simultaneous measurement of temperatures at multiple points.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Environmental Industry Expo 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition aims to pave the way for a sustainable future from the local community. It is a trade fair for environmental-related industries originating from the Minami-Shinshu region of Nagano Prefecture. Our company will introduce next-generation solutions for reducing environmental impact and effectively utilizing energy, including our "smokeless small incinerator" and "stove," along with product panels and case studies. No pre-registration is required, and admission is free. We sincerely look forward to your visit.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
