Hydrogen Pressure Sensor

      🌟 ISO 9001:2005 certified quality System

Hydrogen-Powered Vehicles

    🌟 Avery’s hydrogen pressure sensor is an ideal choice for hydrogen-powered fuel cell vehicles. 
    The sensors will be installed in vehicles for measuring tank pressure and the pressure of hydrogen before released to fuel cells. 
    The sensing element is made of one-piece 316L material, and has passed all standards for hydrogen pressure cycles and burst pressure requirements.
Hydrogen Storage Tank

    🌟 In order for making hydrogen storage tanks smaller and creating a lighter, 
    mobile system, high pressure is needed for compressing the volume of hydrogen occupied. 
    Avery offers a wide range of hydrogen pressure sensors covering ultra-high pressure ranges which are common to hydrogen storage tanks.

Hydrogen Filling Station

    🌟 Avery’s hydrogen pressure sensor is an ideal choice for use in hydrogen filling station, 
    no matter at conventional type of station or warehouse using hydrogen-powered fork lifts. 
    The sensors can serve the purpose to monitor storage tank pressure, compressor controls, as well as dispensing pressure.
Hydrogen Power

    🌟 Nowadays hydrogen has become a viable and feasible solution to replace conventional fossil fuels for environmentally friendly power generation. 
    In this regard Avery’s sensors will typically be installed to measure the manifold pressure of hydrogen injection, as well as the pressure of on-site storage.

Key Features - I-GLAZ Technology
🌟 MEMs-Based Bulk Silicon Piezo-Resistive Pressure Sensing

🌟  Inorganic Bonding Process of Silicon to Stainless Steel, Titanium, or Nickel / Cobalt Alloys

🌟  Digital Signal Compensated

🌟  One Piece Structure

🌟  Non-welded, No Oil-filled and No Internal O-Ring

Why I-GLAZ Matters?
 🌟 Part of compliance to TUV, UL, CSA standards involves media compatibility

🌟 Effects of hydrogen permeability and embrittlement must be tackled

🌟 Sensor material needs to be correctly selected to ensure long and trouble-free service in hydrogen

Tackling Hydrogen Embrittlement

 ⚡ 🌟Austenitic steels (e.g. 316L) with low carbon content are well suited to avoid hydrogen embrittlement

🌟 Other factors that make 316L the ideal material for pressure sensors:
Molybdenum

🧡 High nickel content

🧡 High stacking fault energy

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

⚡ Diaphragm Membrane of Avery Instrument Hydrogen Pressure Sensor

Other Key Features

    ⚡ One piece structure design

    ⚡ No oil-filled cavities - no chance of containment

    ⚡ Non-welded diaphragm - no leak paths and weak points

    ⚡ Compliant to CE EN61326

PEM Fuel Cell for Vehicles

Application

🌟 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.

Hydrogen Storage

Application

🌟 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

Hydrogen Power Generator

Application

🌟 Hydrogen becomes environmental friendly option to replace diesel for stand-by power generation
🌟 Usable to backup power generator
🌟 Pressure sensors be used to ensure containment of hydrogen to sensing element plus regulatory approvals to maintain safety
🌟 Typically to measure manifold pressure injecting hydrogen as well as on-site storage pressure

Hydrogen Filling Station

Application

🌟 Sensors designed for measuring hydrogen pressure at filling stations
🌟 Usable to monitor storage tank pressure, compressor controls and dispensing pressure
🌟 Sensors customizable for explosion-proof and non-incendive features for hydrogen filling stations

Hydrogen Forklift

Application

Benefits of hydrogen fuel cell over lead-acid battery
🌟 No pollutants emitted
🌟 Eliminate disposal of lead-acid batteries
🌟 Longer fuel cell life cycle (10-12 years vs 5 years)
🌟 Hydrogen refueling faster than battery charging (2-5 minutes vs 15-17 hours)
🌟 Longer run-time between fills (18 hours vs 4-6 hours)
🌟 Our sensors applicable to both storage tanks and forklift's fuel cell

Hydrogen Service in Oil Industry

Application

Benefits of hydrogen fuel cell over lead-acid battery
🌟 Oil companies need to develop new sources for petroleum from bituminous sands and deep below the ground
🌟 Pressure sensors needed to detect level of hydrogen emitted
🌟 Presence of hydrogen and hydrogen sulphide will cause erosion to sensor materials
🌟 Materials with high levels of cobalt and small quantity of molybdenum (e.g. 316L steel) will help to minimize erosion
