Keller Company High-Precision Pressure Sensor Series 23SX-H2 for Hydrogen Applications
High-precision pressure sensors for hydrogen applications have finally arrived!
The 23SX-H2 series is characterized by a low embrittlement rate due to an increased nickel content in the stainless steel used. The gold-plated diaphragm minimizes the diffusion of H2. Additionally, the pressure sensor is compensated across the entire temperature range and has excellent long-term stability. The 23SX-H2 series is a reliable solution that offers long life, high precision, and safety, meeting all hydrogen requirements. 【Features】 〇 Adoption of stainless steel with increased nickel content as a countermeasure against hydrogen embrittlement 〇 Use of gold-plated diaphragm widely used in hydrogen applications to minimize hydrogen diffusion 〇 Achieves ±0.25% accuracy within -10 to 80℃ 〇 Standard equipped with two outputs: digital RS485 and analog output 〇 Analog output can be range-changed via digital RS485 〇 Excellent long-term stability 〇 Welded structure without internal seals 〇 Available in intrinsically safe explosion-proof type (33X-Ei-H2)
