Description

  • Designed to sense low differential pressures between high pressure sources
  • Cast-aluminum housing available in explosion-proof or weather-tight options
  • Frictionless switching mechanism, which amplifies the movement of the switching element, resulting in improved life, repeatability, and lower deadbands.
  • Accommodates up to four full size SPDT electric switches, which are available in a variety of configurations, including:  adjustable deadband, DPDT, high/low operation, & manual reset
  • Switch configurations can be supplied with low deadband, high direct current ratings, gold contacts, hermetically-sealed contacts
