I presented at the 2025 public symposium (13th edition) of the Self-Medication Research Laboratory at Meiji Pharmaceutical University.

KELLER Pressure is a leading manufacturer of piezoresistive pressure sensors. We will showcase high-precision pressure sensors, compact pressure sensors, and high-speed response pressure sensors with the specifications listed below, focusing on pressure sensors and digital pressure gauges that have a proven track record in the aerospace and aviation fields. We will explain why KELLER Pressure products are chosen in the aerospace and aviation sectors and what sets them apart from competitors using the exhibited products. 【Example of Achievements】 Rocket (fuel, oxidizer), satellites (atmospheric pressure measurement during re-entry), combustion pressure measurement, aircraft attitude control, detonation, International Space Station (ISS), etc. For those who wish to have meetings or product introductions at our booth on the day of the event, we are accepting reservations in advance. Interested parties can contact us at sales.jp@keller-pressure.com. 【Exhibition Content】 We offer a variety of pressure sensors suitable for a wide range of measurements: 　〇 Low pressure to high pressure (0.5 kPa to 200 MPa) 　〇 Low temperature to ultra-high temperature (-50℃ to 1000℃) 　〇 High precision (± 0.01%FS and above) 　〇 Compact (Φ 1.4 x 3.1 cm and above) 　〇 Ultra-fast response 　〇 Digital display pressure gauges

● What is a hydrogen leak detector? It can measure leaks in small areas that could not be detected in air leak tests and can also identify the leak locations. It is a detector that uses a mixture of 5% hydrogen and 95% nitrogen (non-flammable gas: ISO10156:2017) as the tracer gas. ● What is a helium leak test system? It is a leak test system suitable for high-precision or high-pressure leak inspections. The helium leak test system uses helium gas as the detection gas (tracer gas) and detects the helium that has leaked out. It is the leak test method among Fukuda's leak testers that can detect the smallest leaks.

We are pleased to announce that our employees have newly passed various levels of the "Machine Inspection" certification in the second half of the 2023 fiscal year. ■ Breakdown of Successful Candidates Special Level of Machine Inspection: 1 person Third Level of Machine Inspection: 3 people The special level requires more than five years of practical experience after passing the first level. The pass rate is very low, and it demands advanced and extensive specialized knowledge. Our company has many other certified professionals as well. You can view them through the link below. We will continue to strive for further technical improvement, strengthen our quality assurance system, and assist everyone in the manufacturing industry.

We would like to introduce the Rooster camera solution provided by San Electronics Co., Ltd. This solution goes beyond traditional surveillance cameras and is an integrated monitoring system that contributes to "crime prevention," "safety management," and "business efficiency" through advanced image analysis using AI and collaboration with various sensors. ■ Background In recent years, issues have become apparent in factories, construction sites, and commercial facilities, such as: - Prevention of labor accidents - Response to labor shortages - Advancement of crime prevention and risk management These challenges are difficult to address with conventional "recording-centered surveillance cameras," and there is a growing demand for AI solutions that enable real-time detection and notification. ■ Features 1. Advanced safety management using AI → Contributes to the prevention of accidents and improvement of on-site safety. 2. Crime prevention and security functions → Enables rapid response through real-time anomaly detection. 3. Collaboration with environmental sensors → Achieves both visualization of the on-site environment and risk management simultaneously. 4. Centralized management via the cloud → Supports reduction of operational burden and rapid decision-making. For more details, please refer to the related products and catalogs on this page.
