Product Overview

The KDP2M transducer can measure either air pressure or velocity with the ip of a

switch. The KDP2M is available in three installation congurations: duct, panel or

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 eld-selectable sub-ranges.

The universal model comes in one pressure/velocity range: 0-10 in. WC / 0-6,000 ft/

min with seven eld-selectable sub-ranges. All variants are available with and without

display. The KDP2M has an IP65/NEMA 4 environmental rating and a 5-year limited

warranty.

Operation

9. Wait ve seconds, then press and hold the ZERO pushbutton for two

seconds or provide contact closure on the AUX ZERO terminal. This will reset

the output and display to zero pressure. For best accuracy, press the ZERO

button while both ports are open to atmospheric pressure. To protect the unit

from accidental zero, this feature is enabled only when the detected pressure

is within about 0.1 in. WC (25 Pa) of factory calibration.

10. Connect desired external tubing to the KDP2M.

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 rst few minutes of operation, readings at

zero pressure and the lowest pressure ranges appear erroneous. Following this

initial warm-up period, the KPDM2 device maintains its specied accuracy and

stability.

The LCD momentarily indicates range ‘SET’ when a selection is made. Pressure

is normally indicated on the display. Units are in inches water column (in. WC),

Pascals (Pa) or kilopascals (kPa) as indicated on the display. The display shows

‘OVER’ when the pressure is over range.

8. Connect the transmitter to the control system and power supply as indicated

below. Optional: Connect the ZERO terminals to the digital output (contact

closure) of the control system.
