Description
The Carrier 48DP400492 Pilot Tube is not a large product, but it is a essentialcomponent of HVAC systems. It is a simple tubular instrument that is employed in order to determine the pressure of air or velocity of air in the system. The pressure between these two openings is the difference and this signal is the airspeed. This measured airspeed information is then used to communicate with the control board of the HVAC system to regulate its functions. For example, where the same is required for control of airflow over heat exchangers for heat exchange purposes.
