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

【What if a massive earthquake halts production at factories, resulting in losses of hundreds of millions of yen!?】 Revealing successful case studies of "DX × Earthquake Countermeasures" to protect the future of manufacturing! A massive earthquake is not something that "will happen someday," but rather "can happen at any time." If a major earthquake were to occur now and halt production lines in factories... businesses would face critical risks to their survival (losses ranging from millions to billions of yen) due to not only damage to buildings and equipment but also delays in delivery and withdrawal of business partners. This document presents real examples of "actual loss amounts and reconstruction costs" that occur in factories during an earthquake, based on data from the Great East Japan Earthquake and the Kumamoto Earthquake. ▼ What you will learn in this seminar Actual damages during an earthquake: Real data on sales losses and reconstruction costs associated with factory shutdowns On-site action guide: A chronological action plan and checklist to follow without hesitation from initial response to recovery Safety measures utilizing DX and AI: The mechanism and estimated costs of systems that detect shaking and automatically stop equipment and enable remote recovery Keys to successful business continuity: How to effectively use earthquake insurance to expedite recovery and case studies from advanced companies ▼ Event Overview Date: September 11, 2026 (Friday) 13:30 - 14:30 Format: Online (Teams Webinar) Participation fee: Free
