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
