The pressure sensor 33X achieves an extremely high accuracy of 0.05% full scale (FS) in the temperature range of 10 to 40°C through a mathematical correction method. An additional option for high precision of 0.01% FS is also available. 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

Recently, we held technical training sessions for the MilkoScan FT3 at five locations nationwide. In this training, we provided a wide range of useful information for operating the equipment, including explanations of the principles and structure of the device, how to create measurement products, daily maintenance, and how to respond to issues when they arise. Additionally, this year we introduced new methods for utilizing digital services (such as FossCalibrator and IQX) and also prepared hands-on sessions where participants could experience operating the equipment using a PC. Thank you to everyone who participated. Please feel free to contact us with any questions after the training. ------- At Foss Japan, in addition to training sessions and workshops to ensure you can use our equipment with confidence, we hold many events throughout the year. In seminars and open houses tailored to specific industries and analytical techniques, we showcase Foss's latest analytical solutions. -------

We will be exhibiting at the "Monozukuri Fair 2026" held at Marine Messe Fukuoka from October 14 (Wednesday) to 16 (Friday). We will have a working model of a "small winch" powered by an electric driver equipped with our uniquely developed self-locking reduction mechanism "shoji-lock," and we will set up a corner where you can experience the actual lifting and lowering of workpieces. Please stop by. (Hall A, Booth Number AS-57)

[Lecturers] EY Strategy and Consulting Co., Ltd. Infrastructure Advisory Partner Kenichiro Fukuda Strategy Partner Ken Fujiyama Infrastructure Advisory Director Takashi Matsumura [Key Lecture Content] The water supply and sewage business is facing structural challenges such as facility aging, a shortage of workforce, and a decrease in revenue due to population decline. The government is promoting the introduction of Water PPPs, regional consolidation, and the digital transformation of water supply and sewage systems, marking a significant turning point in the way these businesses are operated. This change is expanding business opportunities for private companies in various areas, including operation and maintenance, pipeline renewal, digital technology, and the utilization of smart meters and data. Additionally, as a means of expanding business domains and enhancing competitiveness, there has been an increase in capital and operational partnerships and M&A between companies, leading to industry restructuring. In this seminar, based on the latest trends in policy and the market, we will introduce business strategies for private companies to enter and expand in the water supply and sewage market, including the use of M&A and capital operational partnerships, drawing on achievements from both public and private support.
