Claims
- 1. A pressure sensor system suitable for HVAC airflow control applications comprising:
a) a simple probe tube located in an area of low turbulence, high velocity airflow of the HVAC airflow; b) the simple probe tube connected to a pressure sensor transducer; and c) whereby the signal from the transducer can be used to monitor the airflow of the HVAC application.
- 2. The pressure sensor system of claim 1 wherein the pressure sensor transducer is connected to a variable speed motor controller for monitoring and controlling the HVAC airflow.
- 3. The pressure sensor system of claim 1 wherein the variable speed motor controller is connected to a blower motor for controlling the HVAC airflow.
- 4. The pressure sensor system of claim 1 wherein the low turbulence, high velocity airflow area is a flow ring surrounding a blower motor.
- 5. The pressure sensor system of claim 4 wherein the blower motor is a variable speed blower motor.
- 6. The pressure sensor system of claim 1 wherein the pressure sensor transducer is a differential pressure sensor.
- 7. The pressure sensor system of claim 6 wherein the pressure sensor transducer is an electronic pressure sensor.
- 8. The pressure sensor system of claim 1 wherein the pressure sensor transducer is an electronic pressure sensor.
- 9. The pressure sensor system of claim 6 further comprising a second tube connected at a second side of the pressure sensor for a reference pressure.
- 10. The pressure sensor system of claim 4 wherein the simple probe tube is part of an assembly comprising a clip for attachment of the simple probe tube to an inside surface of the flow ring.
- 11. The pressure sensor system of claim 2 wherein the HVAC airflow is monitored and controlled directly from the pressure sensor transducer.
- 12. The pressure sensor system of claim 2 wherein the HVAC airflow is monitored and controlled from the pressure sensor transducer and in conjunction with other data.
- 13. The pressure sensor system of claim 4 wherein the flow ring has the highest velocity in the HVAC airflow.
