The VTH73 Hydrogen Pressure Sensor features a safe and reliable structural design specifically crafted for high-pressure hydrogen storage. By utilizing a one-body AISI 316L stainless steel design with no oil-filled cavities, it eliminates the risk of internal leakage and hydrogen permeation. This all-welded hydrogen sensor avoids welding diaphragms entirely to enhance overpressure resistance in hydrogen refueling stations. It delivers up to ±0.25% Accuracy and operates reliably in extreme temperatures from -40°C to +120°C. With a compact, weatherproof outline and short circuit protection, it provides a stable, long-term solution for PEM fuel cells and hydrogen fuel vehicle test benches.
