The Dwyer EDPS-08-1-N Differential Pressure Switch, model J-490, is a reliable and accurate instrument designed to monitor and respond to changes in pressure differences within various industrial and commercial applications.
This pressure switch features an 8-inch (203.2 mm) differential pressure range, which makes it suitable for monitoring moderate to large pressure differences. The switch is designed with a simple yet effective construction, featuring a stainless steel diaphragm that separates the sensing chamber from the control chamber. This design ensures that the switch can effectively measure the pressure difference between two points without being affected by the process media.
The EDPS-08-1-N Differential Pressure Switch is also equipped with a rugged, all-welded, and explosion-proof enclosure that is constructed from cast aluminum. The enclosure is designed to provide maximum protection against harsh environments, making it an ideal choice for applications in the oil and gas, chemical, and pharmaceutical industries.
The switch has a standard threaded connection of NPT (National Pipe Thread) 1/2"-18 UNF (Unified National Thread) and comes with a factory-set differential pressure point of 2-6 psi (13.8-41.4 kPa). However, the differential pressure setting can be easily adjusted using the provided adjusting nut, allowing users to customize the switch to meet their specific application requirements.
The EDPS-08-1-N Differential Pressure Switch is designed to provide reliable and accurate switching action, with a quick response time and low hysteresis. It is also equipped with a built-in test port, which allows users to perform routine tests and maintenance on the switch without disrupting the process.
The switch comes with a factory-installed and adjustable 1/4"-20 UNF threaded output that can be configured for either a normally open (NO) or normally closed (NC) contact. This versatile output allows users to integrate the switch into various control systems and applications.
The Dwyer EDPS-08-1-N Differential Pressure Switch, model J-490, is a high-performance and durable instrument that is designed to provide reliable and accurate pressure monitoring and switching action in even the most demanding industrial and commercial applications. Its rugged construction, adjustable differential pressure setting, and versatile output make it an indispensable tool for process control and safety systems.
