In addition to a digital RS485 interface, analog current or voltage outputs can be obtained. 【Features】 - Accuracy of ±0.05% FS in the temperature range of 10 to 40°C - Standard dual outputs of digital RS485 and analog output - Analog output can be range-adjusted via digital RS485 - Available in barometric range type (800–1200 hPa) and differential pressure range type (from 0–30 kPa to 0–3 MPa) - Temperature range of -20 to 125°C (optional -40°C also available) - Excellent long-term stability 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model to produce accurate pressure values

• Pressure

Ideal for measuring pulsations and unsteady behavior with a bandwidth of 50 kHz, temperature-resistant up to 180°C, built-in amplifier (0-10V output) high-precision pressure sensor.

The ultra-high-speed pressure sensor M5HB can measure not only static pressure but also pressure changes within a bandwidth of 0 to 50 kHz. This is achieved by the digital circuit continuously adjusting the analog signal in real-time, with an output of 0 to 10V. The compact sensor head with M5 fine thread can be used at temperatures up to 180°C. It has a pressure resistance of up to five times the measurement range and is an excellent model for vibration resistance. 【Features】 - Temperature resistance of the sensor head: 180°C - Output is an analog signal of 0 to 10V (with built-in amplifier) - Wide temperature compensation range: -20 to 125°C or -40 to 180°C - Bandwidth of 50kHz, ideal for measuring pulsations and unsteady behavior - Resistant to impacts and vibrations - Compact design, pressure connection is M5×0.5 fine thread

• Pressure

±0.05% accuracy / Digital pressure gauge with logging function, explosion-proof type available

The high-precision digital pressure gauge LEO Record can record pressure and temperature for extended periods thanks to its memory function. The data logger can be connected to a computer via an RS485 interface for reading the recorded data. The current pressure value can be displayed in multiple pressure units. It is powered by a 3.6V lithium battery. An intrinsically safe explosion-proof type is also available. 【Features】 - Can record pressure and temperature for long periods - High precision (±0.05%FS @ 20–25 °C) - Ultra-low power consumption, long battery life - Can display in various pressure units (bar, mbar, hPa, kPa, MPa, PSI, kg/cm2, cmH2O, mH2O, etc.) - Zero point calibration via button - Intrinsically safe explosion-proof type available

We will be exhibiting from Wednesday, October 1 to Friday, October 3, 2025. Makuhari Messe https://www.jagri-global.jp/hub/ja-jp/visit/feature-t/plant.html Please stop by!

To construction and civil engineering companies looking for the "next" step in digitalization. This seminar will explain the currently trending topic of "AI utilization" in 45 minutes. We will clearly introduce the latest trends, specific case studies, and steps for implementation to address questions such as "What can AI do?" and "How can it be applied to our business?" Whether your company is already advancing in DX or is just starting to consider AI, you will find hints for improving operational efficiency. 【Schedule】 1: Company introduction and instructor introduction 2: Case studies of AI utilization in the construction and civil engineering industry 3: Convincing examples! Patterns of AI utilization in construction operations 4: Three steps to avoid failure in AI implementation 5: Q&A and closing remarks

We will address the issue of young employees who, despite joining the company, leave due to reasons such as "there's no time to be taught," "I don't understand when I'm told to learn by watching," and "what is written and said varies depending on the project or person in charge." We propose a system that accumulates the know-how of veterans in AI and systems, allowing young employees to search for and solve problems on their own. 【Schedule】 1: Company introduction and instructor introduction 2: Reasons why technical inheritance is not progressing (lack of time, difficulty in verbalizing) 3: "Next-generation manual and know-how sharing methods" utilizing video and AI search 4: Examples of system construction to institutionalize technical inheritance 5: Q&A and closing remarks
