DIFFERENTIAL PRESSURE SWITCHES

ITT Neo Dyn's temperature switches come in two different types: 

  • 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 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. Our Neo-Dyn switches feature a negative rate Belleville spring snap acting device which offers greater set point stability, vibration resistance, over-pressure capability and cycle life.
  • A hermetically sealed enclosure is completely sealed from the environment and our Neo-Dyn hermetically sealed electrical assemblies are all metal with a glass header. All joints are soldered or welded to insure sealing integrity. Our explosion-proof enclosure is capable of withstanding an explosion which may occur within, and capable of preventing the ignition of an explosive atmosphere which may surround it. Plus you get the same benefits from our Belleville spring; greater set-point, vibration resistance, capability and cycle life.
