Series 1800 Low Differential Pressure Switch

Known for quality, reliability and accuracy, Dwyer designs and manufactures a full-line of Controllers, Data Loggers, Gages, Manometers, Monitors, Remote Displays, Switches, Transmitters, and Accessories to measure, monitor and control pressure, air velocity, flow, fan pressure, duct, and more.

Dwyer’s wide selection extends to Gages, Transmitters, Switches, Data Loggers, and Monitors for Differential Pressure. Dwyer manufactures a range of dial and digital gages to reliably measure and display pressure difference, between two pressure sources using gas or liquid in a process flow.

Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures. Applications vary between the different types of differential pressure switches. A wide variety of switches and circuit styles enables control functions needed for any system.

Essential for industrial environments, the Series 1800 Low Differential Pressure Switch combines small size and low price with 2% repeatability for all but the most demanding applications. Set point adjustment inside the mounting stud permits mounting the switch on one side of a wall or panel with adjustment easily accessible on the opposite side. UL and CSA listed, and FM approved.

Features

  • Compact size and repeatability provide a high-value switch for many industrial applications
  • Designed for panel and wall mounting to easily meet mounting requirements in most industrial settings
  • Pressure ranges from 0.07 in w.c. to 85 in w.c. make this switch suitable for a wide range of applications

Application

  • Process applications
  • Mechanical equipment control
