Digital Pressure Gauge Guide

Digital Pressure GaugeThis guide will help you choose a digital pressure gauge by pointing you to the best product with a particular feature or function you need for testing, monitoring or recording pressures.

Digital pressures gauges are more accurate and easier to read to a higher level of precision than mechanical dial pressure gauges.

Analogue dial pressure gauges are not as accurate as solid state pressure gauges due to the accuracy and stability of strain gage sensing technology over the bourdon tube technology used in most dial pressure gages.

There is no ambiguity when reading a digital pressure gauge, because unlike analogue dial pressure gauges, there is no parallax error caused by viewing a needle on a dial with limited resolution at different angles.

Select Application Type

Pressure range type

Choose the range of pressure which your required range falls within to view matching product details.

High Precision

High precision pressure test gaugeHigh precision pressure test gauge for accurately monitoring test pressures or using as a master test gauge to calibrate other pressure instruments. This gauge can be used with pneumatic or hydraulic hand pumps to accurately set calibration pressures as part of ISO9000 quality calibration procedures. This instrument can be provided with a UKAS accreditation calibration certificate for traceability purposes.

Intrinsically Safe

EEx certified digital pressure gaugesEEx certified digital pressure gauges for use with potential flammable gases and liquids. These gauges have been approved to the European ATEX regulatory standard for limiting electrical discharge or excessive heat to prevent the ignition of a volatile gas or liquid.

Pressure ranges

Flush Diaphragm

Flush diaphragm digital pressure gaugeFlush diaphragm digital pressure gauges for use on viscous media to prevent blocking of process connection and allow the removal of any residual process material.

BSP P Thread

BSP P parallel thread connection pressure gaugeBSP P parallel thread connection pressure gauge with different size & style of BSP-P (British Standard Pipe Parallel) threaded process connections such as 1/4 inch BSP and 1/2 inch BSP. Choose DIN3852 style connections for sealing with dowty or bonded seals around the outside of the thread or with EN837 (DIN16288) which use smaller O ring gaskets on the tip of the male BSP process connection.

NPT Thread

NPT tapered thread connector pressure gaugeNPT tapered thread connector pressure gauge with 1/4 or 1/2 inch NPT (National Pipe Thread Tapered) male thread process connectors for sealing with thread sealant or PTFE tape.

Hygienic / Sanitary

Hygienic & sanitary pressure gaugeHygienic & sanitary pressure gauge for measuring the pressure & hydrostatic level in food & pharmaceutical applications. The is pressure gauges has an all stainless steel 316L front end construction with the option for food grade oil fill for full compliance with food, dairy, beverage, medical & biotech requirements for cleaning and prevention of contamination.

LCD display

LCD digital display pressure gaugeLCD digital display pressure gauge with a liquid crystal display which extends the battery life allowing continuous use over long periods of time to monitor process pressures.

LED display

LED readout electronic pressure gaugeLED readout electronic pressure gauge with highly visible light emitting diode readouts to enable easy reading of pressure from a distance or in areas where there are poor lighting conditions. Due to the increased power consumption of the LED digital display, this gauge require an external low voltage DC power supply.

Features & Functions

Digital pressure gauges open up a wealth of functionality that will help you enhance your pressure test results and analysis.

Changing Pressure Units

LEX1 plus displayThe most requested feature for digital pressure gauges is the ability to change pressure units and most gauges provide this function. Not all gauges will convert every pressure unit though, it can vary from a choice of just bar/psi, to many more, so it is worth checking the spec first to make sure all the units that you need to convert are included.

The LEX1 is a multi-unit pressure gauge used for displaying pressure readings in different units.

Max/Min Values

LEO1 Peak modeYou can’t always be present to check the pressure of a process, so how do you know whether the pressure has risen or fallen while you were away? A maximum/minimum or peak/valley hold feature would give you some idea of what has happened between visual checks. This feature will continually monitor the pressure and update the memory with the highest and lowest reading reached.

The LEO1 is a max/min hold pressure gauge used in pressure testing to record the lowest and highest reading.

Internal Data Storage

Standard version of LEO RecordA step up from the max/min hold is a full data logging capability where you can manually or automatically set intervals for storing each pressure reading in a larger capacity memory. Some gauges will allow you to review the test results via the gauge’s digital display or upload them via a computer interface for detailed analysis.

The LEO Record is a battery powered logging pressure gauge used to store data within the device and uploading to a computer for analysis at a later time.

Linking to a Computer

LEO3 Current or Digital Output Pressure GaugeA similar function is to provide a USB or RS232 interface for gauges which do not have sufficient internal memory for logging. This enables readings to be logged remotely from the gauge onto a computer, but you must maintain a live connection between the gauge and computer otherwise nothing will be recorded.

The LEO3 is a computer connection pressure gauge used for logging directly to the computer screen.

Reference Standard

ADT672Higher end pressure gauges incorporate displays with a high digit resolution and solid state high precision pressure sensors, which makes them useful for checking performance of other pressure measurement equipment. For example a dial gauge has very low resolution especially if the dial is small, so it is difficult to discern an error, but with a precise digital gauge there are plenty of digits to measure even the slightest error.

The ADT672 is a reference standard pressure gauge used for calibration.

Switch and Signal Output

DS200 Combined Pressure Switch, Gauge and SensorIf external power is available at the intended location for the pressure gauge, you can consider using an output signal such as a switched voltage signal that triggers at values programmed via the front panel display. Alternatively you could also use a variable voltage or current signal for transmitting the pressure reading back to control instrumentation.

The DS200 is a switch and signal output pressure gauge which is used for process control as well as local reading indication.
