Product Overview

The Dwyer 1638 Series Precision Pressure Switches are designed for HVAC systems, process control, and industrial applications requiring accurate pressure activation. Available in models including 1638-5, these switches deliver reliable performance in demanding environments.

Key Features

Visible Set Point Indicator: Clear, easy-to-read dial enables real-time visualization of pressure set points for simplified setup, operation, and troubleshooting.
Large Diaphragm Design: Provides precise pressure sensing in low ranges for reliable activation at exact pressure points, ideal for applications with minor pressure fluctuations.
High Current Load Capability: Supports up to 15 amps, eliminating the need for additional relays in most small electrical systems.
Versatile Model Selection: Includes models for various pressure ranges from ultra-low (1638-0) to higher low-pressure applications (1638-1/2/5/10).
Rugged Construction: Built to withstand industrial environments in HVAC ducts, process lines, and mechanical systems.

Typical Applications

Fan coil systems, air handlers, fluid level monitoring, HVAC installations, pump control, and process equipment.
