🔮 Avery Instrument Niche Applications

      Waste Water Treatment
     
      🌟 Pressure sensors needed to ensure high reliability, stability, 
  chemical compatibility and quality control for protection of waste water system

🌟 Sensors to be deployed for performing:

⚪ Water level monitoring (to access degree of system utilization)

⚪ Flow measurement (to prevent overloading caused by heavy rain)

⚪ Differential water level measurement (to prevent clogging and abrasion)

      Viscous Media Tanks
      
⚡ Examples of viscous media: melted plastics, paper pulp, bitumen, 
rubber, asphalt, crude oil, paint, sealants, certain foods and pharmaceutical products

⚡ Sensors needed measure level and flow rate of viscous fluid

⚡ Special pressure sensors needed for viscous media to prevent clogging, chemical 
compatibility and to handle extremely harsh environments.
Steel Mills
⚡ Pressure sensors needed at different processes in steel mills to monitor:

⚪ Hydraulic pressure

⚪ Pressure of gas supply and air inlet

⚪ Pump and water pressure of cooler

⚪ Pressure of compressed air

⚪ Flow measurement of air

⚪ Hydraulic level measurement, etc.

🎡 AV40HT High Temperature Pressure Sensor

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

Oil and Gas Tanks
 ⚡ Pressure sensors needed so as to keep operations running smoothly and safely

    ⚡ Processes which need pressure sensing include wellheads, hydraulic fracturing, 
    service trucks, drilling tools, mud systems, compression systems and vapor recovery units, etc.

    ⚡ Special sensor needed to monitor viscous flow in some processes (e.g. mud flow)

       All of these sensors are designed
