SDP-PC10AU Gold-Plated Piezoresistive Silicon Pressure Sensor Core
The SDP-PC10AU is a Ø19 mm piezoresistive silicon pressure sensor core designed for hydrogen pressure measurement. A gold-plated 316L stainless steel diaphragm helps reduce hydrogen permeation, while its silicone-oil-filled construction transfers pressure to the sensing element. With pressure ranges from 100 kPa to 40 MPa, it supports OEM integration into hydrogen pressure sensors and transmitters.
Features
• Gold-Plated Diaphragm — Helps reduce hydrogen permeation for hydrogen pressure measurement.
• Standard Ø19 mm Design — Compact Ø19 × 14 mm construction for OEM integration.
• 316L Stainless Steel — Gold-plated 316L diaphragm and 316L housing with welded sealing.
