The Dwyer Model 1950-02-S Differential Pressure Switch, Type 341334, is a versatile and reliable instrument designed for monitoring and controlling differential pressure in various industrial applications. This switch offers accurate and consistent performance, ensuring optimal system efficiency and maintaining desirable process conditions.
The 1950-02-S Differential Pressure Switch is a pneumatic switch, operated by the pressure difference between two process lines. Its compact design, with an overall size of 2.125 inches (54.0 mm) in diameter and 3.125 inches (79.4 mm) in length, makes it suitable for installation in tight spaces. The switch features a sturdy, die-cast aluminum housing, providing durability and resistance to harsh industrial conditions.
This differential pressure switch operates on a spring-loaded diaphragm, which senses the pressure difference between the two process lines. When the pressure difference across the switch reaches the preset value, the diaphragm deflects, actuating the switch and triggering an output signal. The switch offers adjustable set points, allowing users to customize the pressure differential at which the switch activates.
The 1950-02-S Differential Pressure Switch comes with a variety of output options, including normally open (NO) and normally closed (NC) contacts, as well as an optional pneumatic output. The switch also features a built-in test port, which allows users to easily perform switch function tests without disrupting the process.
The switch's operating temperature range is from -40 F to 257 F (-40 C to 125 C), ensuring reliable performance in a wide range of industrial environments. It is also compatible with various process media, including water, air, and gases, making it a versatile instrument for various applications.
The Dwyer Model 1950-02-S Differential Pressure Switch is easy to install and maintain. It comes with a mounting template and clear markings for proper orientation, ensuring a quick and accurate installation process. The switch also features a removable diaphragm, allowing for easy cleaning and maintenance.
In summary, the Dwyer Model 1950-02-S Differential Pressure Switch, Type 341334, is a high-performance, versatile, and reliable instrument designed for monitoring and controlling differential pressure in various industrial applications. Its compact design, adjustable set points, and various output options make it a valuable asset for optimizing system efficiency and maintaining desirable process conditions.
