Pressure Switches for Industrial Applications
Industrial pressure switches provide reliable on/off control and safety shutdown based on preset pressure thresholds. They are widely used for pump protection, filter monitoring, compressor control and safety interlocks across mining, water treatment, chemical, food and general industrial plants. Available in both mechanical and electronic designs, pressure switches offer simple, robust and cost‑effective pressure monitoring.
Types of Pressure Switches
- Mechanical Pressure Switches – Simple, rugged and ideal for pump control, compressors and general industrial use.
- Electronic Pressure Switches – Digital switching, display options and higher accuracy for modern automation systems.
- Differential Pressure Switches – For filters, strainers and ventilation systems.
- High‑Pressure Switches – For hydraulic systems and heavy industrial applications.
