KELLER will exhibit at the Hydrogen and Fuel Cell Exhibition! February 19-21, 2025, at Tokyo Big Sight, East Hall 1, E6-6.

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)

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensors wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ Bed exit sensors wirelessly notify in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
