Digital Pressure Gauges for Industrial Measurement

GNW digital pressure gauges provide clear electronic pressure indication for industrial monitoring, maintenance, testing and calibration applications. The collection includes compact 63 mm gauges, 100 mm industrial models and a 105 mm high-accuracy reference gauge, with measuring ranges extending from vacuum through to 1600 bar.

The GNW260 series provides ±1.0% full-scale accuracy for general pressure monitoring and equipment checks. The GNW200 series offers ±0.4% full-scale accuracy for more demanding industrial measurement and pressure comparison tasks, while the GNW210 provides ±0.05% full-scale accuracy for calibration and instrument verification work.

Available models include gauge pressure, vacuum, compound pressure and absolute pressure versions. Depending on the product, connection options include 1/4-inch BSP, 1/2-inch BSP and 1/4-inch NPT, with bottom-entry configurations and stainless steel case, bezel and wetted parts.

Pressure ranges, accuracy, connection options, power supplies and calibration certification vary by model. Review the individual product specification to select a digital pressure gauge that suits the expected operating pressure, required accuracy and installation.

Digital Pressure Gauges vs Analogue Pressure Gauges

Digital and analogue pressure gauges both provide local pressure indication, but they display and measure pressure in different ways. Analogue gauges use a mechanical movement and pointer, while digital pressure gauges convert the pressure signal into a numerical reading shown on an electronic display.

A digital display can make readings easier to interpret and removes the need to estimate values between scale divisions. Digital gauges are often useful for maintenance, pressure testing, equipment setup and applications where small changes in pressure need to be clearly observed.

Analogue pressure gauges remain suitable for many permanent installations where simple mechanical indication is required and no electrical power supply is available. They can provide a straightforward and cost-effective solution for routine pressure monitoring.

The most suitable type depends on the required pressure range, accuracy, operating environment, power supply and installation. Digital models may be preferred where clear numerical indication or a specified higher level of accuracy is required, while analogue gauges remain practical for many general industrial applications.

Clear Numerical Pressure Readings

Digital pressure gauges display pressure as a direct numerical value, reducing the need to estimate readings between the scale divisions found on an analogue dial.

Battery-Powered Measurement

Battery-powered digital gauges can provide convenient local pressure indication for maintenance, equipment checks and test work where a fixed power supply is unavailable.

Digital and Analogue Options

Digital gauges are useful where clear numerical indication is required, while analogue gauges remain a practical choice for simple, permanently installed mechanical pressure indication.

Digital Pressure Gauge Applications

Digital pressure gauges are used across industrial applications where clear electronic pressure indication is required. Models are available for general monitoring, maintenance, pressure testing and higher-accuracy reference measurement.

Hydraulic Systems and Power Units

Digital pressure gauges provide clear local indication on compatible hydraulic systems and power units during pressure monitoring, equipment setup and maintenance checks.

Pneumatic and Compressor Systems

Suitable models can be used on compressors, pneumatic equipment and air systems for operating-pressure checks, system monitoring and diagnostic work.

Calibration and Instrument Verification

Selected higher-accuracy and reference models can support pressure gauge calibration, comparison and instrument verification when used with suitable pressure generation equipment and procedures.

How to Choose the Right Digital Pressure Gauge

Selecting the correct digital pressure gauge depends on the pressure range, required accuracy, process connection, operating environment and intended application.

Choose the Correct Pressure Range

Select a measuring range that comfortably exceeds the highest pressure expected during normal operation, including anticipated pressure fluctuations or short-duration peaks.

Consider the Required Accuracy

Different digital gauges provide different levels of measurement accuracy. Calibration and instrument verification may require a higher accuracy specification than routine pressure monitoring or maintenance checks.

Check the Connection and Materials

Confirm that the process connection matches the system and that the wetted materials are compatible with the pressure medium. Available connection sizes and materials vary by model.

Review the Display and Power Supply

Consider the case size, display format and available power options. Battery-powered gauges support portable use, while selected models also provide USB power for workshop and test-bench applications.

Digital Pressure Gauge FAQs

Find answers to common questions about digital pressure gauges, including how they work, where they are used, accuracy considerations and calibration certification.

What is a digital pressure gauge?

A digital pressure gauge uses an electronic pressure sensor to measure pressure and displays the result as a numerical reading on an LCD screen.

What are digital pressure gauges used for?

Digital pressure gauges are used for industrial pressure monitoring, hydraulic and pneumatic system checks, maintenance, pressure testing and equipment setup. Selected higher-accuracy models are also suitable for calibration and instrument verification work.

Are digital pressure gauges more accurate than analogue gauges?

Not necessarily. Accuracy depends on the specification of the individual instrument. Digital gauges provide clear numerical readings and may offer higher accuracy or resolution, while analogue gauges remain suitable for many general pressure-monitoring applications.

Can digital pressure gauges be supplied with a calibration certificate?

Yes. Calibration certification is available for selected digital pressure gauges. It may be supplied as standard or offered as an optional extra depending on the model, so check the individual product specification before ordering.
