The Dayton Part Number 12T084 is a 1/4 NPT (National Pipe Thread) pressure switch designed for applications requiring a normally open, double pole, single throw (DPST) contact mechanism. This pressure switch is suitable for use with various fluid mediums and can be utilized in various industries such as HVAC, water treatment, and process control systems.
The 12T084 pressure switch features a compact, robust design, making it an ideal solution for space-constrained installations. It is constructed of brass, ensuring durability and resistance to corrosion. The switch housing is threaded with a 1/4 NPT connection, allowing for easy installation and integration with existing piping systems.
The switch operates on a differential pressure principle, meaning it requires a difference in pressure between two ports to activate the contacts. The switch is factory set to activate at a specific differential pressure, but it can be easily adjusted to meet the requirements of various applications. The adjustment range for the 12T084 model is 0-25 PSIG (pounds per square inch, gauge).
The contacts on the Dayton 12T084 pressure switch are rated for a maximum current of 1.5 amps at 125V AC or DC, making it suitable for a wide range of applications. The contacts are gold plated to ensure optimal conductivity and prolonged service life.
The switch also includes a built-in test button, which allows users to manually test the switch's functionality without the need for external tools or equipment. This feature is particularly useful during installation, commissioning, or maintenance activities to ensure the switch is operating correctly.
In summary, the Dayton 12T084 pressure switch is a versatile and reliable solution for applications requiring a compact, 1/4 NPT, DPST pressure switch with a differential pressure operating principle. Its robust construction, adjustable setting, and easy-to-use test button make it a valuable addition to various industrial and commercial systems.
