Honeywell Pressuretrol PA404A Pressure Controller with additive differential, 0.5 - 9 psi, 3-3/8 Inch W x 4-15/32 Inch H x 2-1/4 Inch D
  • Pressure actuated high limit, safety control for steam heating boilers, It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level
  • Contains an SPST Micro switch snap-acting switch
  • Sensitive pressure actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
  • A screw on top of the case allows setpoint adjustment without removing the cover
  • Differential is adjusted by means of a dial located inside the case
  • Recommended minimum setpoint is differential setting plus 1-1/2 psi
  • Stainless steel diaphragm sensor element
  • Makes at setpoint on pressure fall breaks at setpoint plus differential on pressure rise Honeywell Pressuretrol PA404A Pressure Controller with additive differential, 0.5 - 9 psi, 3-3/8 Inch W x 4-15/32 Inch H x 2-1/4 Inch D

Sid Harvey C354-1R Pressuretrol Controller, SPST, 0.5-9 psi Adjustable, 3-3/8" W x 4-15/32" H x 2-1/4" D, Remanufactured
  • The PA404 is a series 40 (2-wire, SPST) pressuretrol controller for use in 24, 120, 240 or 277 volt control circuits or in self powered (millivoltage) applications
  • The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam
  • Each model contains an SPST micro-switch snap-acting switch
  • Sensitive pressure-actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
  • A screw on top of the case allows set point adjustment without removing the cover
  • Differential is adjusted by means of a dial located inside the case
  • Recommended minimum set point is differential setting plus 1-1/2 psi
  • Tradeline value
  • Stainless steel diaphragm sensor element
  • Additive or subtractive differential type
  • Makes at set point plus differential on pressure rise, breaks at set point on pressure fall
  • 50 psi pressure surge
  • 0.5-9 psi adjustable scale range
