The KMC SSS-1000 sensors are designed to sense
differential pressure in the inlet section of VAV (Variable
Air Volume) terminal units and fan terminal
units. They can also be used to sense differential
pressure at other locations in the main or branch
duct systems. The differential pressure read between
the high “H” port and the low “L” port can be used
to determine the air flow. Static pressure can also be
measured using just one of the ports rotated 90°.
These sensors are typically used in conjunction
with the CSC-1000/2000/3000 series, CSP-4000/5000
series, KMD-7000 series, and BAC-7000 series of
VAV controllers for individual zone control in HVAC
systems.
For using SSS-100x sensors with CSC-3000 series,
CSP-4000/5000 series, KMD-7000 series, and BAC-
7000 series controllers, use a 3/8" to 1/4" barb union
adapter and appropriate polyethylene tubing to the
sensor and controller. For maximum accuracy in the
CSP-5000 series, KMD-7000 series, and BAC-7000
series controllers, the 3/8" OD tubing between the
sensor and the adapter should be as short as possible,
and the 1/4" OD tubing from the adapter to
the controller should be 24" long (on both the High
and the Low sides). OR use the equivalent SSS-101x
sensor.
