The switch comes with a threaded connection, specifically a 1/4 NPT (National Pipe Taper) female inlet, allowing for easy installation and integration with existing systems.
The pressure switch features a rugged and durable construction, ensuring it can withstand harsh industrial environments. It is made of high-quality materials, including a brass housing and stainless steel diaphragms, providing excellent corrosion resistance. The switch's operating pressure range is from 3 to 10 bar (43.5 to 145 psi), making it suitable for a wide range of applications.
This pressure switch is easy to install and operate. It includes a built-in adjustable spring, allowing you to set the desired pressure point within a range from 0.5 to 10 bar (7 to 145 psi). The switch's operating principle is simple: when the pressure in the system reaches the set point, the diaphragm deflects, which in turn activates the switch contacts.
