Dwyer Instruments 1823-10 Low Differential Pressure Switch w.c. - 2.0-10

The Dwyer Instruments 1823-10 is a low differential pressure switch designed for HVAC, clean room, and building automation applications where precise monitoring of air pressure differentials is critical. This unit is factory set to activate within the 2.0 to 10 inches water column (w.c.) range, making it ideal for filter monitoring, duct pressure control, and air flow verification systems.

Key Features:

• Adjustable setpoint range: 2.0 to 10 inches water column
• SPDT snap-action switch provides reliable contact operation
• Compact, flush-mount design for easy installation in tight spaces
• Durable diaphragm construction ensures long service life
• Clear cover allows visual inspection of setpoint adjustment
• Two pressure ports with 1/8" NPT female connections
• Suitable for air and compatible non-combustible gases

This differential pressure switch is commonly used to monitor filter conditions, detect blocked filters, control fan operation, and maintain proper building pressurization. The adjustable setpoint allows for precise calibration to meet specific application requirements, while the snap-action switch mechanism provides consistent, repeatable performance.
