Description
Dwyer 1638 Series Precision Pressure Switches
Product Overview

The Dwyer 1638 Series Precision Pressure Switches, including models 1638-0, 1638-1, 1638-2, 1638-5, and 1638-10, are engineered for HVAC systems, process control, and industrial applications requiring accurate pressure activation.

Dwyer 1638 Series Precision Pressure Switch with Visible Set Point Indicator, Large Diaphragm for Low-Range Accuracy, and High Current Load Capability
Key Features
  • Visible Set Point Indicator: Clear, easy-to-read dial allows real-time visualization of pressure set points, simplifying setup, operation, and troubleshooting while reducing downtime.
  • Large Diaphragm for Low-Range Accuracy: Precise pressure sensing in low ranges ensures reliable activation at exact pressure points, ideal for applications with minor pressure fluctuations.
  • High Current Load Capability: Supports current loads up to 15 amps, eliminating the need for additional relays in most small electrical systems and reducing installation complexity.
  • Versatile Model Selection: Multiple models cover various pressure spans to match diverse application requirements.
  • Rugged Construction: Built to withstand industrial environments with durable performance in HVAC ducts, process lines, and mechanical systems.
Available Models
  • 1638-0: Ultra-low range for delicate pressure sensing
  • 1638-1/2/5/10: Graduated ranges for medium to higher low-pressure applications
Applications

Ideal for fan coil systems, air handlers, fluid level monitoring, HVAC installations, pump control, and process equipment where responsive pressure control is essential.
