Abstract

A remote zone balancing damper and air flow sensor system comprising a differential pressure air flow sensor, a damper having an actuator, a remote terminal connected to the air flow sensor and the actuator, the remote terminal disposed a predetermined distance from the duct, the air flow sensor and damper mounted in a duct, and a detachable controller that is connectable to the remote terminal, the detachable controller configured to receive a signal from the remote terminal and to provide power to the actuator and thereby position the damper according to the calculated air flow.

Claims

1. A remote zone balancing damper and air flow sensor system comprising:

a differential pressure air flow sensor;

a damper having an actuator;

a remote terminal connected to the air flow sensor and the actuator, the remote terminal disposed a predetermined distance from the duct;

the air flow sensor and damper mounted in a duct; and

a detachable controller that is connectable to the remote terminal, the detachable controller configured to receive a signal from the remote terminal and to provide power to the actuator and thereby position the damper according to the calculated air flow.

2. The system as in claim 1, wherein the controller comprises an energy source for energizing the actuator.

3. The system as in claim 1, where in the controller comprises a visual display.

4. The system as in claim 3, wherein the controller comprises:

a processor connected to the visual display;

a pressure transducer connected to the air flow sensor and to the processor; and

the processor using a signal from the pressure transducer to calculate an air flow rate, the air flow rate displayable on the visual display.

5. The system as in claim 1, wherein the air flow sensor is disposed upstream of the damper.
