Differential Pressure / Air Velocity Transducer
Product Overview
KDP2M
The KDP2M transducer can measure either air pressure or velocity with the flip of a
Patent Pending
switch. The KDP2M is available in three installation configurations: duct, panel or
50
universal. Duct and panel models have two pressure and velocity options: 0-1 in. WC /
0-3,000 ft/min or 1-10 in. WC / 3,000-6,000 ft/min with four field-selectable sub-ranges.
NOTICE
The universal model comes in one pressure/velocity range: 0-10 in. WC / 0-6,000 ft/

Velocity with FXP Probe
For velocity applications, use the FXP Series air velocity/measurement probe or AA18,
AA19 or AA20 velocity pitot tubes. For use with the PX3P (panel) and PX3U (universal)
models in Velocity mode only. Sold separately.
2. For duct mount applications, thread the probe into the back of the device housing, as
shown in the dimensional drawing.
3. Configure the internal tubing for the selected installation method as described below.
Duct mount tubing configuration:
a. Connect the right-side tube to the rear brass barb marked as "-" on the
underside of the device housing.
b. Connect the left-side tube to the probe in the back of the device housing.
Panel mount tubing configuration:
a. Connect the right-side tube to the rear brass barb marked as "-" on the
underside of the device housing.
b. Connect the left-side tube to the front brass barb marked as "+" on the
underside of the device housing.

- Page 2 10. Connect desired external tubing to the KDP2M. Operation The KDP2M Series devices employ high performance sensors and sophisticated temperature compensation circuitry. The sensor achieves its best accuracy after an initial warm-up period. During the first few minutes of operation, readings at zero pressure and the lowest pressure ranges appear erroneous.
