Precise Pressure and Vacuum Measurement Critical for Aerospace, Aviation, and Wind Tunnel Applications

Common Pressure & Vacuum Measurement Applications

Precise pressure and vacuum measurement is critical across many industries and applications. Some of the most common uses for pressure and vacuum monitoring include:

HVAC Systems

In HVAC (heating, ventilation and air conditioning) systems, pressure sensors monitor the airflow and duct pressure to ensure proper ventilation, heating and cooling. Typical HVAC pressure ranges are 25 Pa to 2500 Pa. Sensors such as differential pressure transmitters and switches are used to measure:

  • Filter status
  • Fan and blower operation
  • Presence of leaks

Manufacturing Processes

Industrial manufacturing relies on pressure measurement for quality control and process monitoring. Pressure sensors are built into equipment like autoclaves, reactors, and hydraulic presses. Vacuum sensors also help monitor vacuum-based processes like food and pharmaceutical lyophilization. Common ranges are -100 kPa to 30 MPa.

Automotive Systems

In automobiles, the engine manifold pressure is monitored along with tire pressure. Pressure sensors help optimize combustion, reduce emissions, and prevent tire blowouts. Pressure ranges are typically 7 kPa to 700 kPa. Vacuum sensors check for intake manifold leaks.


Altimeters measure air pressure to determine aircraft altitude. Barometers forecast weather based on pressure changes. Ranges are 20 kPa to 115 kPa. Pitot tubes use differential pressure to calculate airspeed. Hydraulic pressure in landing gear and flight controls is also monitored.

In addition, vacuum sensors verify pressurization in cabins and test wind tunnels for aerodynamic simulation. Vacuum ranges used are typically 1 Pa to 5 kPa.

Across these applications, the choice of pressure or vacuum measurement device depends on factors like the required range, accuracy, environment, and cost. Proper setup and calibration is key to achieving reliable measurements.

With the growth of automation and IoT, pressure and vacuum monitoring is becoming more digital, networked and predictive. Smart sensors provide continuous diagnostics and data analysis for improved uptime and process optimization.

Manufacturing Processes

Manufacturing involves creating products from raw materials through different physical and chemical transformations. Manufacturing processes utilize specialized equipment, tools and energy to turn materials into finished goods. Some key manufacturing processes include:

Casting and Molding

Casting pours molten metal into a mold cavity to form parts like engine blocks or machine housings. Molding injects or compresses material into preset mold shapes. Types of molding include:

  • Injection molding for plastics
  • Blow molding for hollow plastic parts
  • Compression molding for heated plastics or composites


Machining cuts away material using power-driven machine tools. Common machining operations include:

  • Turning - rotates workpiece against a cutting tool
  • Milling - rotates cutter against stationary work
  • Drilling - penetrates straight holes
  • Boring - enlarges existing holes

Welding and Joining

Welding uses heat or pressure to fuse materials together. Main techniques are:

  • Arc welding - uses electrical arc to melt and join metals
  • Resistance welding - uses electric current and force to heat metals
  • Soldering - flows filler metal between close-fitting parts

Adhesives chemically bind components and fasteners mechanically join them.

Additive Manufacturing

Additive processes build up parts layer-by-layer from 3D model data. Additive methods include:

  • 3D printing - binds powder or solidifies liquid material
  • Stereolithography - cures photosensitive resin with lasers

These techniques enable rapid prototyping and creation of intricate, lightweight geometries.

Sheet Metal Working

Sheet metal is formed into parts using mechanical force. Common sheet metal processes are:

  • Bending - produces V, U and channel shapes
  • Drawing - stretches sheet metal over a die
  • Stamping - uses dies to cut specific outlines

Presses provide the necessary forces for sheet metal working. Sheet hydroforming uses fluid pressure instead.

Manufacturing processes must be selected based on product requirements, materials, production volumes and cost targets. Automated manufacturing maximizes precision and efficiency. Sensors monitor key process parameters like position, force, temperature and pressure.

Automotive Systems

Modern automobiles consist of complex interconnected systems that work together to power, steer, stop, and control the vehicle. Some key automotive systems include:


The engine generates power by burning fuel within cylinders. Major engine components are:

  • Cylinder block and head
  • Crankshaft and pistons
  • Valvetrain (camshaft, valves)
  • Fuel injection and ignition

Sensors monitor parameters like engine speed, temperature, knock, and emissions to optimize performance.


The drivetrain transmits engine power to the wheels. Main elements are:

  • Clutch and transmission - vary torque and speed
  • Driveshaft and axles - route power to wheels
  • Differential - allows wheels to rotate at different speeds


The suspension provides a smooth ride and stable handling by absorbing bumps and vibrations. Key components are:

  • Shock absorbers and struts
  • Control arms
  • Leaf or coil springs
  • Anti-roll bars

Steering System

The steering changes wheel direction to maneuver the vehicle. It has:

  • Steering wheel
  • Steering column and shaft
  • Rack and pinion or recirculating ball mechanism
  • Linkages to wheels

Power steering uses hydraulic or electric assist for easier turning. Advanced systems add computerized controls and sensors for automation.

These and other essential systems like brakes, electrical, HVAC, and safety are interconnected in modern network-controlled vehicles. Integrated operation and diagnostics optimize overall vehicle performance.

Aerospace/Aviation Applications

Advanced pressure and vacuum measurement technologies play critical roles in aerospace and aviation. Some key applications include:

Aircraft Altitude

Altimeters measure air pressure changes to determine aircraft altitude. Typical altimeters contain:

  • An aneroid capsule that expands/contracts with pressure
  • A calibrated spring to oppose capsule motion
  • Pointers to indicate altitude

Radio altimeters use radar signals to measure height above terrain. Ranges up to 30,000 ft are common.

Airspeed Measurement

Differential pressure sensing with a Pitot static tube calculates airspeed. The tube has two openings:

  • Pitot - Measures total (static + dynamic) pressure
  • Static - Measures ambient static pressure

The difference between the two readings determines airspeed. Typical range is 100-700 mph.

Engine Monitoring

Sensors measure intake and exhaust pressures for engine health monitoring and fuel optimization. Parameters monitored include:

  • Manifold pressure
  • Turbine discharge pressure
  • Bleed air pressure

Vacuum sensors also check for air leaks in the intake manifold.

Aircraft Cabin Pressurization

Vacuum pumps and controllers maintain cabin pressure during flight. This allows people to breathe normally at high altitudes. Cabin differential pressure is typically maintained at around 8 psi.

Wind Tunnels

Wind tunnels recreate flight conditions on the ground for testing. Vacuum pumps are used to simulate high altitude conditions. Typical pressures range from 150 psi down to near vacuum.

Advanced pressure and vacuum measurement technologies continue to support aviation safety, efficiency, and performance. Smart sensors, remote diagnostics, and condition monitoring provide further benefits.

Vacuum System PDF

A basic vacuum system is composed of essential elements that are required to obtain high vacuum. The system typically includes a vacuum pump, a vacuum gauge, a vacuum valve, and a vacuum chamber. To achieve ultra-high vacuum (UHV) conditions, metal gaskets are necessary, allowing baking of the whole chamber to about 520 K while the vacuum pumps operate. The materials used inside vacuum chambers have to be chosen very carefully to avoid high vapor pressure. Vacuum technology is growing in importance as more industries introduce advanced materials and devices and as technology advances. There are different types of vacuum pumps available, such as mechanical pumps, diffusion pumps, and ion pumps, each with its own advantages and disadvantages. The pumping speed is one of the critical parameters in vacuum system operation, which is the rate at which the atoms flow from the regions of high pressure.
