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.
