The Neo-Dyn® Advantage Install It and Forget It with “SNAP” Technology

Durable, Reliable Switches for Harsh Environments Pressure Switch Design - the key to “SNAP” Technology Nega-Rate® Belleville Spring A negative rate type pressure switch (i.e., a Belleville spring) is a SNAP acting device. At a certain pressure (apex of the spring curve) the spring snaps over center. At this point, it takes less pressure (force) to continue its movement. The pressure switch set point is a function of the Belleville spring. The electrical switch is in a fixed position and is synchronized to the movement of the Belleville.

Stable Set Points Eliminates Constant Recalibration • Not affected by variables imparted by the application • No wearing elements directly attached • No changes with temperature variations STABLE SET POINTS Vibration Resistance Eliminates Contact Chatter • Belleville SNAP maintains electrical contacts • Low mass and Belleville SNAP prevent contact chatter • No spring mounted components to shake around and break contacts VIBRATION RESISTANT Over-Pressure Capability No Affect on Set Point Accuracy • Pressure isolated at the diaphragm or piston • High safety factor pressure sensing parts stop...
