Measuring the pressure of hydrogen - In the case of hydrogen fuel cells

The pressure sensor for hydrogen applications has finally arrived!

The 23SY-H2(Ei) series is characterized by a low embrittlement rate due to an increased nickel content in the stainless steel used. The gold-plated diaphragm minimizes hydrogen diffusion. Additionally, the pressure sensor is compensated across the entire temperature range, providing excellent long-term stability. The 23SY-Ei-H2 series is a reliable solution equipped with long life, high precision, and safety, meeting various hydrogen requirements. 【Features】 〇 Adoption of stainless steel with increased nickel content as a measure against hydrogen embrittlement 〇 Use of gold-plated diaphragm widely used in hydrogen applications to minimize hydrogen diffusion 〇 Achieves ±0.7% accuracy within -10 to 80°C 〇 Excellent long-term stability 〇 Welded structure without internal seals 〇 Available in intrinsically safe explosion-proof type (23SY-Ei-H2)

The digital pressure gauge for hydrogen applications has finally arrived! With logging function.

The high-precision digital pressure gauge LEO Record H2 is a digital pressure gauge that can record pressure and temperature over long periods. By increasing the nickel content in stainless steel, it ensures a low embrittlement rate and a long service life. Additionally, the gold-plated diaphragm minimizes the diffusion of H2. With the RS485 interface, the pressure gauge can be easily connected to a PC for settings and data retrieval. Its high accuracy and safety allow the LEO Record H2 to meet the requirements for measuring instruments in the hydrogen field. 【Features】 • Use of stainless steel with increased nickel content to counter hydrogen embrittlement • Gold-plated diaphragm to minimize hydrogen diffusion • Records pressure and temperature • High data security with non-volatile memory • Ultra-low power consumption / long battery life • Various pressure units selectable (bar, mbar, hPa, kPa, MPa, PSI, kg/cm2, etc.) • Zero point calibration via button • Recording function can be manually started and stopped • Various recording function settings available • Available in intrinsically safe explosion-proof type (LEO-Record-Ei-H2)

• Pressure

High-precision pressure sensor with RS485 digital output. Atmospheric pressure range (800 to 1200 hPa) is also available!

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

Ultra-compact pressure sensor with a minimum diameter of 17mm, covering from 0 to 200kPa up to 0 to 100MPa!

The pressure sensor series 21Y features a welded structure that does not use internal seals. It has an insulation voltage of 300VDC, making it less susceptible to disturbances.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

When it comes to hyper CLT sheets, many people may have the image of sheets used at construction or civil engineering sites. However, the potential of hyper CLT sheets (NETIS registration number TH-250021-A) goes beyond that. We believe that hyper CLT sheets can be utilized not only as "site materials" but also as "materials that support gathering places." One representative scene of this utilization is event venues. At event venues, there are many situations where it is necessary to temporarily protect the ground or create a safe environment for passage, such as outdoor events, local festivals, exhibitions, around temporary stages, food truck areas, material delivery routes, and pedestrian pathways for visitors. In this way, hyper CLT sheets have the potential to contribute to creating a foundation for people to gather, move safely, and use spaces, going beyond the framework of being merely "sheets for construction." Hyper CLT sheets have the potential to be active not only at construction sites but also in various situations such as event venues and temporary spaces. We do not want to think of "sheets" as something only for sites, but rather we aim to further expand their possibilities in the future.
