- "K51" SERIES ADJUSTABLE DIAPHRAGM PRESSURE SWITCH
K51 diaphragm pressure switches maintain the electro-mechanical characteristics present in the K5 series, the only difference being the drive mechanism, substituting a diaphragm function in place of the piston. The preset pressure is adjusted by rotating a graduated knob or, for the economical version, by a setscrew located on top of the unit. Both systems are supplied with a device that permits locking the desired set pressure. Mechanical stops protect both the spring and the micro switch from over pressurization.
