Pressuretrol Controller SPST 0.5-9 psi Adjustable REMANUFACTURED

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,
