Barksdale Series 8000 Compact Pressure Switch

The Series 8000 mechanical switch incorporates all the manufacturing knowledge and experience that has earned Barksdale's Compact Switches the reputation of top quality and robustness in a competitive industry. With 6 different pressure ranges between 6 and 8,700 psi (0.4 to 600 bars), customers have the option to select either the diaphragm model or the piston version to meet their specific application needs. A large choice of pressure port blocks bolted on the CETOP flange provide customers the flexibility to order various pressure ports independent of the switch, keeping inventory costs low.
