Series Pressure Switch |
Our most popular series combines advanced
design and precision construction to make these switches able to perform
many of the tasks of larger, costlier units. Designed for air conditioning
service, they also serve many fluidics, refrigeration, oven and dryer applications.
For air and non combustible compatible gases, series 1900 switches have
set points from 0.07 to 20 inches of water. Set point adjustment is easy
with range screw located inside conduit enclosure. Internal location helps
prevent tampering.
Manual reset model 1900MR includes a special snap switch which latches on pressure increase above the setpoint. Switch must be manually reset after pressure drops below the setpoint. |
