Differential Pressure Switches

Differential Pressure Switches act when the pressure difference between two ports reaches a set point. Products in this category span ACI, Omega Engineering, and Dwyer Instruments metal and plastic differential switches, industrial SPDT and DPDT switches, OEM mechanical switches, air-control switches, low differential switches, floating-contact designs, and adjustable inH2O or Pa ranges.

Applications include:

• Filter blockage and airflow proof alarms
• Duct static pressure and damper control
• Fan, blower, and equipment status interlocks
• Industrial differential pressure alarm points

Choose by setpoint range, repeatability, deadband, contact rating, enclosure, media compatibility, and whether the switch is used for alarm or control.
