Visualizing processing points! Load sensors that enable real-time anomaly detection.

PiezoBolt is a load sensor that incorporates a piezoelectric sensor unit embedded within a bolt that meets JIS standards. By utilizing the piezoelectric effect, which generates voltage when force (pressure) is applied, it is capable of measuring minute changes in load. When combined with a measurement system, it enables real-time monitoring of equipment and tools, as well as anomaly detection. ◎ High Sensitivity Excellent responsiveness, allowing for highly sensitive measurements. ◎ Ease of Use Compliant with JIS standard bolt sizes, it can be installed directly in place of existing bolts for measurement. ◎ Durability With a dust and water protection rating equivalent to IP65, it can be used up to 80°C. A high-performance sensor suitable for mass production environments. ◎ Flexibility The piezoelectric element responds to axial forces, detecting changes not only in compression but also in tension.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers. For more details, please refer to the related link.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
