Pressure Sensors in Hydrogen Engine Racing Cars - Hydrogen Innovation in Motorsports

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)

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.
