Dwyer 616KX-025-110-IN Differential Pressure Transmitter 10 to 35 Vdc (0 to 20 in w.c., 0.25% FSO)

Product Description

The Dwyer 616KX-025-110-IN is a differential pressure transmitter providing 0.25% FSO accuracy for a unidirectional 0 to 20 in w.c. range. It supports field-selectable current and voltage outputs (including 4 to 20 mA and multiple Vdc ranges), accepts 10 to 35 Vdc supply, and features a compact molded housing with stepped barb process connections and an edge-mounted push-button zero for HVAC and OEM pressure monitoring.

• Accuracy ±0.25% FSO for 0 to 20 in w.c.; unidirectional differential pressure measurement
• Field-selectable outputs: 4 to 20 mA, 0 to 5 Vdc, 1 to 5 Vdc, 0 to 10 Vdc, 2 to 10 Vdc; loop resistance 0 to 1250 Ω
• Stepped barb fitting (1/8, 3/16, 1/4 in) for tubing, screw terminal electrical connection, edge-mounted push-button zero

Product Highlights

Compact differential pressure transmitter with 0.25% FSO accuracy, multiple selectable output signals, 10 to 35 Vdc supply, and stepped barb process connections for HVAC and OEM applications.
