Tackling Hydrogen Permeation

🌟 Such failure mechanism caused as a result of sensing membrane
🌟 Oil-filled sensors employ very thin isolation diaphragm typically with 0.025mm thickness
🌟 Hydrogen "plus" ions will escape through diaphragm with such thickness
🌟 As thickness increases (say 0.18mm) such permeation tends to stop subject to the operating temperature

Application - PEM Fuel Cell for Vehicles

🌟 MEMs-Based Bulk Silicon Piezo-Resistive Pressure Sensing
🌟 Sensors be used for measuring tank and hydrogen pressures before release into fuel cell
🌟 The one-piece 316L sensing element is capable to pass all standards for hydrogen pressure cycles and burst pressure requirements.
🌟 Meet environmental conditions such as high pressure wash-down, salt water submersion, dust conditions, shock and vibration.
🌟 Electrical conditions simulated for up to 300V/m of EMI protection.

Application - Hydrogen Storage

🌟 Due to the small size of hydrogen ions, correct material compatibility and construction of components exposed to hydrogen is critical.
🌟 Our sensors able to eliminate leak paths common to other pressure sensor designs
🌟 Sensing elements applicable to ultra-high pressure ranges common to hydrogen storage
🌟 Storage tanks be smaller by compressing hydrogen at higher pressures, creating lighter and mobile system

Warranty

🔮 Workmanship - Avery Instrument Limited (AVERY) pressure sensors have a limited one-year warranty to the original purchaser. AVERY will replace or repair, free of charge, any defective sensor. This warranty does not apply to any units that have been modified; misused, neglected or installed where the application exceeds published ratings; the label getting lost, broken,or unrecognizable when return.
Installation/Applications - The purchaser is responsible for media compatibility, functional adequacy, and correct installation of the sensor.
