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,
