Dwyer Series PG Gas Pressure/Differential Pressure Switch PGW-7200-804-P1

Dwyer Series PG Gas Pressure/Differential Pressure Switch PGW-7200-804-P1

Product Introduction

The Dwyer Series PG Gas Pressure/Differential Pressure Switch is engineered with a large sensitive diaphragm and a time-tested mechanical design, ensuring reliable pressure monitoring for air and compatible gases. Featuring excellent ±1% full-scale repeatability, it offers precise control with a clear, easy-to-read scale and convenient external setpoint adjustment. Designed for application flexibility, the switch supports various configurations—including SPST, SPDT, DPST, and DPDT—with options to trigger on increasing pressure, vacuum, or differential pressure. The PG series is ideal for industrial environments, offering manual reset functions (on PR/PRL models) and durable switch types (mercury or hermetically sealed snap switches) to suit different operational needs.

Product Features

Precision Sensing Design:

Large diaphragm ensures accurate pressure detection for precise control in industrial applications.

±1% full-scale repeatability guarantees consistent performance across cycles.

User-Friendly Operation:

Clear, easy-to-read scale enables quick visual monitoring of pressure settings.

External setpoint adjustment allows intuitive on-site calibration without disassembly.

Versatile Switching Configurations:

Multiple switch types: SPST, SPDT, DPST, DPDT (single/double pole, single/double throw).
