The sensor could be mounted in a concealed location where it will be exposed to the cabin temperature or it may be found within the air duct system to control air blend doors for individual passenger comfort. These sensors are great for people who own homes that don't have cold air return duct work, like my home. Test run (room temperature sensor selection) CAUTION The temperature sensor of the indoor unit or the remote con- troller can be used to detect the room temperature. Temperature duct sensors and averaging duct temperature sensors. Step by step guide on how an automotive mass air flow sensor (MAF) works. Customize sensor lengths and time interval settings. These holes are only there to blow hot air on the sensor every time they go by. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. Recommendations. If the ceiling below the duct is open, you could do most of the work from below. Pictures of how to replace the temperature control door if it breaks on Pontiac Torrent or Chevy Equinox. 3) – Asystem is dynamic when there is rapid thermal response from the heat source, rapid thermal transfer, and frequent changes in the workload. When the temperature changes the bi-metal expands and triggers a snap action switch and either opens or closes a circuit. A "Wireless Temperature Sensor" is placed inside your equipment, constantly measuring the temperature and transmitting a data Logs with the readings at regular intervals. What Is A Damper and What Does It Do? Air duct dampers are also commonly known as HVAC dampers and duct dampers.
