Usage Examples

• (A device measuring the air pressure in the compressor.)
• (A gauge that indicates the air pressure inside a tire.)
• (An instrument monitoring the pressure inside the boiler.)

Advanced Usage

• "to read a pressure-gauge": to interpret the measurement displayed on the gauge.

  • The engineer read the pressure-gauge carefully to avoid overpressurization. (He looked at the gauge and understood the pressure level.)

• "to calibrate a pressure-gauge": to adjust the gauge so that it provides accurate readings.

  • The technician calibrated the pressure-gauge against a standard reference. (He fine-tuned the device for precision.)

Variants and Related Words

• Pressure (n): the continuous physical force exerted on or against an object.
  • The pressure in the tank increased as the gas was added. (The force per unit area.)
• Gauge (n): an instrument that measures and displays a quantity, such as pressure, temperature, or level.
  • The fuel gauge indicated the tank was nearly empty. (A measuring device.)

Synonyms

• Manometer: a specific type of pressure-gauge that uses a column of liquid to measure pressure.
• Pressure meter: a general term for any instrument that measures pressure.
