DA-21-3-5S MERCOID Differential Pressure Switch

The Mercoid DA-21-3-5S Differential Pressure Switch is an essential device designed for monitoring and controlling systems where pressure differences need to be maintained within a specific range. This switch is suitable for applications involving liquids or gases and can handle a maximum working pressure of 60 psi (pounds per square inch).

The Mercoid DA-21-3-5S is a pneumatically operated switch that comes with a 3-way solenoid valve. It features a differential pressure range of 0.5 to 10 psi, which allows it to accurately detect small pressure differences in the system. The switch body is constructed from robust brass material, ensuring durability and resistance to corrosion.

The switch operates by maintaining a balanced pressure on both sides of a diaphragm. When the pressure difference across the diaphragm exceeds the set point, the diaphragm moves, actuating the solenoid valve. This results in the valve opening or closing, depending on the application, to signal an alarm or activate an auxiliary device.

The Mercoid DA-21-3-5S Differential Pressure Switch is easy to install, with a simple wiring configuration that includes three terminals: common, normally open, and normally closed. The switch also comes with an adjustable spring, allowing users to set the pressure point according to their specific application requirements.

This Mercoid switch is also designed with a fail-safe feature, ensuring that it returns to its normal position when the pressure difference is within the acceptable range. It features a compact size, making it an ideal choice for space-constrained installations.

In summary, the Mercoid DA-21-3-5S Differential Pressure Switch is a reliable and versatile device that enables users to monitor and control pressure differences in their systems. Its robust construction, easy installation, adjustable spring, and fail-safe feature make it an excellent choice for various industries, including HVAC, water treatment, and manufacturing.
