The VTMH530 hydrogen pressure sensor provides vital functions and is certified for measuring hydrogen pressure. This pressure sensor has been tested and approved for use in automotive applications based on the EC79 standard. The sensor has a 316L stainless steel sensing element that can fully control the hydrogen pressure. This primary sensor uses a cavity without welds or liquid filling to ensure long-term stability and operational functions. VTMH530 can be packaged for various storage tank pressure and fuel cell regulator applications.
The VTMH530 features VORTORQ’s proprietary micro-fused technology pressure sensing element. The thread, hex, and diaphragm are machined from one piece of 316L SS, eliminating the risks associated with other sensor technologies, including media compatibility, weld failures, and contamination through an oil-filled cavity. The MP5300 pressure sensors passed all tests, including media compatibility, ageing, corrosion resistance, endurance testing, pressure cycling, leakage testing, isolation, noise compatibility, and hydraulic strength. The thick diaphragm of the 900 bar (13,053.4 PSI) pressure sensors held the 1,800 bar burst pressure test and continued to operate above 2,400 bar until the O-ring was extruded.
