Frequently asked questions:

What is a pressure switch?
A pressure switch is used to control and monitor the pressure in pneumatic or hydraulic systems. Pressure limits for any application are programmable with the use of our pressure switches. When the pressure reaches its set pressure point, an output of pressure is implemented, improving the operation and its safety.
We offer electronic, vacuum, filtration and mechanical pressure switches. Our wide range of pressure switches is sourced from world-leading brands, to deliver high performance, long life and optimise operations.
What is a pressure switch used for?
It is to control and monitor hydraulic and pneumatic pressures in a system, to ensure that the minimum and maximum programmed pressures for the specific application are maintained. This results in an optimisation for a safe increase in production and efficiency.
What is a pressure switch on a pump?
A pump pressure switch signals the pump in question to start or stop pumping, according to the programming of the switch.
How does a pressure switch activate?
The hydraulic or pneumatic pressure proceeds up the diaphragm which presses against a piston and spring, allowing the outlet to open or close.
How do you calibrate a pressure switch?
It is important to ensure that your pressure switch offers an accurate pressure reading to increase the safety of your operation and prevent downtime. Contact our experts for assistance.
What are two types of pressure switches?
Mechanical and electronic pressure switches. We offer both, as well as vacuum and filtration pressure switches. This table explains the difference between the two types of pressure switches:

 
Mechanical pressure switches
Mechanical pressure switches convert fluid pressure into mechanical movement and are a cost-effective and reliable solution. It is used in a range of applications, especially those which require conversions of high currents such as those in pumps and drives.

A mechanical pressure switch is typically used in single-switch contact applications, and in safety critical applications as a redundant component, instantly kicking into action when pressure crosses a critical, pre-set point. Our range of mechanical pressure switches caters for both low demand (few switching cycles) and high demand (frequent switching cycles). Switches have a pre-set or configurable mechanical adjustment of the switch point.

Our mechanical pressure switches offer a range of features, including optional leakage ports, control lamps, lockable rotary knobs and micro switches with NC/NO contact function. Electronic connections include cable gland, plug-in or large cubic connectors.

 
Electronic pressure switches
Electronic pressure switches are used in applications requiring an electronic output signal. It provides more control configurability than mechanical switches with an integrated programmable logic, so switch points and output signal can be defined according to your requirements.

The electronic pressure switch is used in applications with multiple switch points and where control flexibility is required. It features a wide range of functions, including delay time, switch point, reset switch point, and hysteresis or window function.

Additionally, our electronic pressure switches feature compact designs, stainless steel and FKM media contacts, two antivalent switching outputs (or one switching output and one analogue output), electronic connection via 4-pole M12 connector and sensor thin film measuring cells.
