ABSTRACT:
A restriction sensor system for identifying the existence of blockages in exhaust conduits of clothes dryers. The restriction sensor system may be used as a retrofit system that is capable of being installed on existing clothes dryers. The restriction sensor system may include a fitting configured to be coupled to an exhaust conduit of a clothes dryer and a blockage indicator housing positioned remote from a clothes dryer. The pressure sensing device may be capable of determining changes in air pressure in the exhaust conduit. Once the air pressure present in the exhaust conduit exceeds a threshold air pressure, the pressure sensing device may send a signal to an indicator to generate an alarm, which may be a visual alarm or audible alarm, or both.
