Pressure Switch Excellence by SNS Pneumatic
In modern industrial automation and pneumatic control systems, the pressure switch plays a crucial role. Acting as both a “guardian” for equipment safety and an “intelligent manager” for production efficiency, pressure switches are indispensable components.
The SNS Pneumatic QPM/QPF series pressure switch stands out for its high accuracy, reliability, and broad applicability, earning the trust of enterprises worldwide.
This article provides a detailed analysis of the technical features, applications, purchasing considerations, and FAQs, helping you make informed purchasing decisions.
What Is a Pressure Switch?
Definition
A pressure switch is an automated control device used to monitor the pressure of gas or liquid in a system.
When the pressure reaches a preset threshold, the switch automatically triggers an electrical circuit, enabling equipment to start, stop, or send out an alarm.
Its primary function is to ensure equipment operates within safe pressure limits, preventing damage or accidents caused by excessive or insufficient pressure.
How It Works
Inside a pressure switch, an elastic element (such as a diaphragm or bellows) reacts to system pressure.
As the element deforms, it activates a microswitch, opening or closing the circuit. Users can adjust the preset pressure value to control equipment operation flexibly.
