Description

Dwyer Pressure Switches (Models 1638-0, 1638-1, 1638-10, 1638-2, 1638-5)

Product Introduction

The Dwyer Pressure Switches (Series 1638) are reliable, precision instruments designed for pressure-based control in HVAC and industrial processes. With models covering a range of pressure spans (e.g., 0–1 psi to 0–10 psi), these switches feature a visible set-point indicator for easy operation and troubleshooting. The large diaphragm design ensures accuracy in low-pressure ranges, enabling precise control of pumps, fans, and valves. Capable of handling current loads up to 15 amps, they directly support small electrical loads without additional relays, simplifying system design and reducing installation costs.

Product Features

Visible Set-Point Indicator:

Front-facing indicator allows quick visual confirmation of pressure set points.

Simplifies on-site adjustments and troubleshooting without specialized tools.

Large Diaphragm Design:

Enhances sensitivity and accuracy in low-pressure applications (e.g., 0–1 psi range).

Enables precise pressure threshold detection for reliable system control.

High Current Load Capacity:

Supports up to 15 amps, suitable for direct connection to small motors, solenoids, and alarms.

Eliminates the need for intermediate relays, reducing component costs and system complexity.

Versatile Pressure Ranges:

Models cover different pressure spans:

1638-0: 0–1 psi

1638-1: 0–2 psi

1638-2: 0–5 psi

1638-5: 0–10 psi

1638-10: (consult datasheet for specific range)

Rugged Construction:

Durable housing suitable for indoor HVAC and general industrial environments.

Reliable performance in typical operating temperatures and humidity ranges.
