Pressure switches and sensors can be used to automatically monitor pressure levels in a pneumatic system, or be used for more complex monitoring functions in air, water, hydraulic or any neutral fluid applications.
Electro-Mechanical Pressure Switches offer an economical way of sensing the pressure in a system, giving a digital signal as an output.

For all the cable, plug and mounting options available for our pressure switch or sensors.
A mechanical pressure switch operates with a spring-set switching point — simple, reliable, and requires no electrical power for measurement. An electronic pressure switch features a digital display, programmable switching points, and analog output — more precise, flexible, and integrable into remote monitoring systems. In industrial automation, electronic versions are increasingly preferred due to better diagnostics and remote parameterization capabilities.
For mechanical pressure switches, use the adjustment screw to set the desired switching pressure. Some models allow the differential (hysteresis — the difference between on and off switching points) to be adjusted with a separate screw, but many simpler models have fixed hysteresis. For electronic versions, the switching point, hysteresis, and delay are programmable via the digital display. Important: always perform setup under pressure, in actual operating conditions.
Typical applications: compressor on/off control, pneumatic system pressure monitoring, emergency machine shutdown on overpressure, filter clogging indication, and process control tasks. NorTrade’s range includes everything from basic mechanical switches to high-precision electronic sensor-type variants — request a quote.
The range depends on the application: for pneumatic systems typically 0-10 bar, for hydraulics up to 0-600 bar. NorTrade’s range includes pressure switches from -1 bar (vacuum) to +600 bar. Overpressure safety is also important — choose a device whose maximum pressure rating is at least 1.5 times the nominal pressure.
When designing and operating pneumatic systems in the EU, the following standards apply: ISO 4414 (general pneumatic safety requirements), EN ISO 13849 (safety controls within machines), and compliance with the 2006/42/EC Machinery Directive. Key principles: the system must always be depressurized before maintenance, maximum operating pressure is determined by the weakest component, and the pressure rating of pipes/hoses must be regularly inspected.
According to the lockout/tagout (LOTO) procedure: shut off the air supply at the main valve, then release residual pressure from the system through the exhaust valve. Verify with a pressure gauge that the pressure is truly zero, and only then perform any work. Never work on a pressurized system.
Send us the original part’s manufacturer code (part number) via the Get a Quote form or email to info@nortrade.hu. Our engineers will identify the product and provide the exact Norgren equivalent, price, and delivery time.
Norgren products are manufactured according to ISO and other international standards, so ISO-standard cylinders, fittings, and valves are physically compatible with same standard products from other manufacturers. NorTrade engineers help with cross-referencing — we provide exact cross-references and technical comparisons. Request a quote.
