Description
The Weil McLain 640-000-011 Flue Temperature Sensor Kit-S W/Mount identifies the exhaust gas conditions inside boiler flue passages and sends readings to the control system to support safe combustion regulation and efficient heat operation. allowing the system to adjust burner activity and prevent unsafe operating conditions caused by overheating or improper draft behavior. The sensor includes a flue temperature probe with mounting hardware for secure positioning on compatible boiler sections and is built to withstand high heat exposure and continuous operation in combustion pathways. In HVAC systems, housed within boiler heating units to track flue gas conditions.
