INSTRUCTION MANUAL

AIR MEASURING CONTROL DAMPER

THERMAL DISPERSION
VEE BLADE
LOW LEAKAGE
STANDARD PERFORMANCE
MODEL: AMD-TD-10

The AMD-TD-10 is an all-in-one airflow measuring and control damper solution that features time-saving and cost-saving installation. In contrast to other airflow measurement products, the thermal dispersion probes offer higher accuracy, even at more turbulent and lower speed airflows. This unit meets the frequently specified leakage criteria of less than 10 cfm per sq. ft at 4″ w.g. (0.5% at 2000 fpm). The damper design features include a sturdy hat channel frame with die-formed corner gussets for reinforcement, a vee groove blade design that maximizes strength and zero maintenance concealed linkage (out of the air stream) for reduced pressure drop and air turbulence.

STANDARD CONSTRUCTION:

DESCRIPTION:

In contrast to having to source all airflow measuring and control items separately, the AMD-TD-10 is offered as an all-in-one, factory assembled and calibrated solution that relieves headaches in parts’ sourcing and installation. The AMD-TD-10 consists of a 1000 series control damper, thermal dispersion technology probes, a BACnet MS/TP capable transmitter, an optional 24 VAC modulating actuator, and an ease-of-access terminal block, all fixed to a sleeve. The probes, transmitter, and actuator are factory wired to the provided terminal block, offering easy, single-point wiring.

OPERATION:

The probes and transmitter use thermal dispersion technology to read the airflow and air temperature, which is displayed on the transmitter. The transmitter outputs a 0 – 10 VDC signal proportional to the real-time airflow and/or air temperature being read, where 10 VDC represents the programmed maximum airflow/air temperature. The factory supplied modulating actuator accepts a 0 – 10 VDC signal that corresponds to how open or closed the damper is.

Turbulent Airflow Correcting Apertures
At the heart of each thermal probe array are pairs of precision matched thermistors installed in aerodynamic apertures. These sensor aperture assemblies are specifically designed to reduce the effects of angular flow distortions found within ducted air distribution systems. The design, construction and calibration of each thermistor sensor pair ensures the accuracy and long term reliability of the measurement system.

APPLICATIONS:

Nailor’s Thermal Dispersion Air Measuring Low Leakage Control Dampers accurately measure airflow in a wide variety of commercial HVAC applications and installations.
