Pressure Switch - Numatics

Pressure switches open or close an electrical contact when pressure reaches a set point. They start and stop pumps and compressors, trigger alarms and shut equipment down when pressure is unsafe.

Pressure Switch Types

• Mechanical switches – simple, reliable and no power needed
• Electronic switches – adjustable set points and displays
• Differential pressure switches – filter and flow monitoring
• Vacuum switches – vacuum system control
• Explosion-proof switches – hazardous areas

Choosing a Switch

Select set point range, deadband, electrical rating and wetted materials. Fixed or adjustable deadband affects cycling. Add snubbers for pulsating systems.
