Dwyer Instruments 1911-00 Differential Pressure Switch WC - 0.07-0.15

The Dwyer Instruments 1911-00 is a compact differential pressure switch designed for HVAC and low-pressure air monitoring applications. This unit operates on a differential pressure range of 0.07 to 0.15 inches of water column, making it ideal for filter monitoring, duct pressure control, and static pressure applications.

Key Features:

• Differential pressure range: 0.07-0.15" WC (water column)
• No enclosure design for installation in protected environments
• Compact switch mechanism for space-limited applications
• Single pole double throw (SPDT) switching output
• Suitable for air and non-combustible, compatible gases
• Factory set differential pressure setpoint

This pressure switch is commonly used in building automation systems, air handling units, and cleanroom applications where precise low-pressure monitoring is required. The unit requires installation in a suitable enclosure or protected environment as it ships without an external housing.
