Description

Dwyer 1638 Series Precision Pressure Switches

Product Introduction

and 1638-5, these switches are ideal for HVAC systems, process control, and industrial applications requiring accurate pressure activation.

Dwyer 1638 Series Precision Pressure Switch for HVAC Systems

Product Features

Visible Set Point Indicator

A clear, easy-to-read dial allows real-time visualization of the pressure set point, simplifying initial setup, operation, and troubleshooting. This feature reduces downtime by enabling quick identification of activation thresholds without additional tools.

Large Diaphragm for Low-Range Accuracy

The switches utilize a large diaphragm design to deliver precise pressure sensing in low ranges, ensuring reliable activation at exact pressure points. This makes them suitable for applications where minor pressure fluctuations require responsive control, such as fan coil systems, air handlers, or fluid level monitoring.

High Current Load Capability

With the ability to support current loads up to 15 amps, the 1638 Series eliminates the need for additional relays or components in most small electrical systems. This simplifies wiring in HVAC installations, pump control, and process equipment, reducing installation costs and complexity.

Versatile Model Selection

Available models cover a range of pressure spans to match diverse application needs:

1638-0: Ultra-low range for delicate pressure sensing

1638-1/2/5/10: Graduated ranges for medium to higher low-pressure applications

Rugged Construction

Built to withstand industrial environments, the switches offer durable performance in HVAC ducts, process lines, and mechanical systems.
