Product Overview

Description and Application
The KMC SSS-1000 sensors are designed to sense
dierential pressure in the inlet section of VAV (Vari-
able Air Volume) terminal units and fan terminal
units. They can also be used to sense dierential
pressure at other locations in the main or branch
duct systems. The dierential pressure read between
the high “H” port and the low “L” port can be used
to determine the air ow. Static pressure can also be
measured using just one of the ports rotated 90°. (See
Sample Applications on page 4.)
Models oer up to four sensing points and sensing
lengths of 3-5/32 to 9-29/32 inches to accommodate
box size diameters of 4 to 16 inches.
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 pos-
sible, 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.
To nd the appropriate sensor “K” factor:
• For digital VAV controllers needing K
CFM
for
setup, see “Cubic Feet Per Minute” K Factors on
page 2.
• For CSC-2000 series, CSC-3000 series, and CSP-
4000 series controllers (needing K
FPM
for setup),
see “Feet Per Minute” K Factors on page 3.
• For CSP-5000, KMD-7000, and BAC-7000 series
that operate dierently—see their respective in-
stallation guides and application guides for more
information.
