What is Bellows Pressure Switch?

Bellows Pressure Switch is a sophisticated control instrument designed to monitor and regulate pressure levels in different environments. The core component of this device is the bellows, a flexible, collapsible tube typically made of metal. The bellows expands or contracts in response to changes in pressure, acting as a sensitive trigger for the switch mechanism.

How it works?

Bellows within the pressure switch is filled with a gas, often nitrogen, which responds to alterations in pressure. When the pressure in the system surpasses or falls below the predetermined threshold, the bellows expands or contracts accordingly. This movement is then harnessed to actuate a switch, completing or interrupting an electrical circuit.

Picture this: in a manufacturing environment, as pressure in a hydraulic system climbs to a critical point, the bellows expands, triggering the switch to shut down the machinery instantly. It’s a ballet of responsiveness, ensuring not only the safety of the equipment but also the protection of valuable resources.
