Product Overview

2 P32 Product Bulletin
Fig. 2 -- Interior view of the P32AA
Differential Pressure Switch.
The setting will change if mounted
in other positions. Mounting with
the steel housing (high pressure
connector) down will increase the
set point by about 0.07 in. W.C.
(0.017 kPa). If mounted with the
steel housing up, the switch may
be inoperative at minimum
setting.
Adjustable models can be
readjusted for other than vertical
plane position on the job.
The P32 can be factory set for a
specific mounting position if
required, on quantity orders.
The field adjustable switches
have an adjusting screw and
optional scale plate concealed by
the cover. Cover must be
removed to change the setting.
Turn the screw CW to increase
the set point or CCW to decrease
the set point.
