Pressure switch
Pressure switches are electromechanical devices designed to monitor and control fluid or gas pressure in industrial systems. These components typically feature adjustable set points, SPDT or DPDT contact configurations, and pressure ranges from vacuum to high-pressure applications (e.g., 0-10 bar, 0-400 bar).

Pressure switches are electromechanical devices designed to monitor and control fluid or gas pressure in industrial systems. These components typically feature adjustable set points, SPDT or DPDT contact configurations, and pressure ranges from vacuum to high-pressure applications (e.g., 0-10 bar, 0-400 bar). They are available in various housing materials like aluminum, stainless steel, or plastic, with IP65 or IP67 protection ratings for harsh environments. Common types include diaphragm, piston, and bourdon tube pressure switches, each suited for specific media compatibility and accuracy requirements. The switching capacity often ranges from 5A to 15A at 250VAC or 24VDC, with options for fixed or adjustable differential.
Pressure switches are widely deployed in industrial automation, HVAC systems, hydraulic and pneumatic circuits, water treatment plants, and compressor control panels. They serve critical functions such as pump start/stop control, safety shutdown in overpressure conditions, and monitoring of filter clogging or tank levels. In process industries, they integrate with PLCs and SCADA systems via digital inputs, ensuring real-time pressure monitoring and alarm generation. Their robust design makes them suitable for oil and gas, chemical processing, and food and beverage sectors where reliability is paramount.
Key subcategories include adjustable pressure switches, fixed differential models, and explosion-proof variants for hazardous areas. Common article codes follow patterns like PS-XXX-YYY, where XXX denotes pressure range (e.g., 010 for 0-10 bar) and YYY indicates contact type (e.g., SPD for SPDT). Examples include PS-010-SPD for low-pressure applications and PS-400-DPD for high-pressure hydraulic systems. Some manufacturers use codes like 9012-XXX or 69XXX series, referencing standardized pressure switch families. Accessories like mounting brackets, cable glands, and pressure ports are often listed separately.
