Pressure & Differential Pressure Switches
Dwyer pressure and differential pressure switches provide reliable on/off control and alarm signaling at user-set pressure points.
Dwyer's pressure switch lines, including the well-known photohelic and switch-equipped gauge designs, deliver dependable set-point control for air and compatible gases. They are used to start and stop equipment, trigger alarms and protect systems when pressure exceeds or falls below preset limits.
Robust construction and adjustable set points make them suitable for filter monitoring, fan interlock and a wide range of HVAC and process safety functions.
- Adjustable set-point pressure control
- SPDT and DPDT switch output options across the range
- Models for positive, negative and differential pressure
- Combined indicate-and-switch designs available
- Durable construction for demanding environments
- Filter clog and fan failure alarms
- HVAC equipment interlock and safety
- Pump and compressor protection
- Process pressure limit control
