Pressure Measurement

Pressure measurement instruments play an important role in process management and control, they’re designed to be used with both gases and liquids to accurately measure and check pressure. From preventing temperatures raising out of permitted ranges to stopping potential explosions from gas build up, we have the equipment to help ensure accuracy and safety in your processes.

How is pressure measured?

Pressure is classified into three types:

  • Fluid pressure – the measurement of force per unit area of a fluid, either liquid or gas.
  • Absolute pressure – the absolute value of force per unit on a surface exerted by a fluid.
  • Gauge pressur e – the difference between atmospheric pressure and absolute. This can differ based on altitude, weather, and ambient temperature. This means pressure gauges readouts can vary at different heights.

Types of pressure measuring devices

There are is a wide range of types of pressure measurement instruments, that can perform here are some of the most commonly used types and what they are used for:

  • Pressure gauges – can be used to measure all types of pressure. They are available in analogue format that uses a scale and needle on a gauge for a readout. Digital pressure gauges are also available that feature a digital screen that provides a reading of higher accuracy. They're commonly used in general industrial applications as well as test applications and calibration.
  • Pressure pumps - pneumatic, vacuum and hydraulic pressure pumps are used to generate pressure quickly and easily to the required level, ideal for calibration applications or machinery maintenance.
  • Pressure meters - are used to measure absolute pressure, negative pressure or differential pressure in air and liquids. They give extremely fast and highly accurate measurements that make them ideal for use in the field of research and development.
  • Pressure calibrators - are devices that not only measure pressure but are used to calibrate (verify) other pressure measurement instrument's readings. They are highly accurate instruments and can have multiple advanced features running at one time, such as a regulator.

Innovations over recent years have allowed for improved technologies to be integrated into devices to allow more data to be collected, take more accurate readings and operate more effectively in challenging environments.
