J21K232

The United Electric J21K-232 Differential Pressure Switch is a versatile and reliable instrument designed for measuring the differential pressure between two fluid lines. This switch is part of United Electric's J21K Series, known for its accuracy, durability, and ease of use.

The J21K-232 is constructed with high-quality materials, ensuring its ability to withstand harsh industrial environments. It features a stainless steel body and a borosilicate glass element, providing excellent corrosion resistance and ensuring a long service life. The switch operates on a bimetallic principle, with two disks of different coefficients of thermal expansion connected by a temperature-sensitive spring. When the differential pressure across the switch reaches the preset value, the bimetallic element deflects, causing the switch contacts to open or close.

The J21K-232 can be used to monitor a wide range of applications, including level measurement in tanks, pressure relief in hydraulic systems, and flow measurement in pumps and compressors. The switch comes with adjustable setpoints, allowing users to customize the operating pressure range to suit their specific application requirements. The switch has a maximum working pressure of 60 psi (4.1 bar) and a temperature range of -40 F to 257 F (-40 C to 125 C).

The J21K-232 is an electric switch, meaning it requires a power source to operate. It has normally open (NO) contacts, which close when the switch is activated. The switch also features a built-in LED indicator, which illuminates when the contacts are closed, providing visual confirmation of switch operation.

Installation of the J21K-232 is simple and straightforward. The switch can be mounted horizontally or vertically, and it requires a minimum of wiring connections. The switch comes with a 1/4-20 UNF threaded connection, allowing it to be easily connected to the fluid lines. The switch also includes a gasket to ensure a leak-free connection.

The J21K-232 is a robust and reliable instrument, designed for use in demanding industrial applications. Its accuracy, durability, and ease of use make it an excellent choice for measuring differential pressure in a wide range of applications. With its adjustable setpoints, built-in LED indicator, and simple installation process, the United Electric J21K-232 Differential Pressure Switch is an essential tool for any industrial process control system.
