Electronic Pressure Switches

Electronic pressure switches are used where the application calls for a high level of accuracy and repeatability, they are robust and reliable and are easy to use with a large display and push button set up procedure. These switches are available either as a PNP or NPN switched output or a combination of a switched output and an analogue output so that pressure can be continuously monitored.View products

About our Pressure Switches Product Range

Pressure switches are widely used for a large range of applications throughout industry and manufacturing. Their function is to provide systems with electrical feedback in response to measuring a rise or fall in pressure. A pressure switch is usually adjustable with regard to the chosen set point of operation.

Also known as pressure sensors, they are used to respond to fluid pressure. For example, a pneumatic pressure switch in compressors and pumps, or hydraulic pressure switches in automotive engineering.

As a leader in the industry, Applications Engineering specialise in providing pressure switches for a huge variety of measurement applications. For simple monitoring systems we offer single pole single throw switches, while for more complicated and advanced requirements we offer a range of single pole double throw switches.

Depending on the application of the pressure switch we can provide different models to best suit your requirements. Whichever of our pressure switches that you choose, you can be sure that it will provide fast, dependable and consistent response regardless of its function.

We supply to a huge variety of companies and business across a broad range of requirements. This could include anything from highly robust and accurate electronic pressure switches to differential pressure switches. If you are not sure which kind of pressure switch is best suited to you, don’t hesitate to get in contact with us today. You can speak to a member of the team who will be able to provide you with expert advice and guidance on choosing a pressure switch.

What is a pressure switch?

Pressure switches, or pressure sensors, are used to provide electrical feedback in response to a chamber either rising or falling to a pre‑determined pressure level being reached.

Where are pressure switches used?

Pressure switches are used in a wide range of industrial and manufacturing applications, such as:

– Well water pumps
– Electronic gas compressors
– In-cell charge control inside a battery
– Activating an alarm if aircraft cabin pressure drops
– Pressure panels on sliding doors
– Switching high currents, e.g., pumps and drives

How do pressure switches work?

Mechanical pressure switches use fluid pressure inside a chamber to activate a physical mechanism, which triggers two contacts within the switch device, either opening or closing the connected apparatus. The pressure point is pre-set as part of factory manufacture, and cannot be adjusted.

Electronic pressure switches will use electronic signals to trigger the switch, and often provide a secondary signal to monitor the pressure within the designated chamber. Switch actuation points are often determined during factory manufacture, but can be adjusted as required via an interface on the device, along with other functionalities.
