Weil McLain 381-356-589 Supply Temperature Sensor

The Weil McLain 381-356-589 is a supply temperature sensor designed for use in Weil McLain boilers. This sensor, typically mounted with a flange for secure attachment, plays a vital role in regulating boiler operation and ensuring efficient heating. The sensor houses a thermistor, a temperature-sensitive resistor. As the water temperature leaving the boiler increases, the thermistor's resistance decreases. This change in resistance is converted into an electrical signal transmitted to the boiler's control board. The control board uses this temperature data to regulate burner operation and water flow. This ensures the boiler maintains the desired water temperature for optimal heating throughout your home. The Weil McLain 381-356-589 Supply Temperature Sensor helps to: Maintain Comfort: By regulating water temperature, the sensor contributes to consistent and comfortable heating throughout your living space. Improve Efficiency:The control board can optimize burner operation based on the water temperature, potentially reducing energy consumption. Safety: In some boiler models, the sensor can trigger safety features if the water temperature exceeds safe limits. While the exact package dimensions (6.26 x 5.28 x 3.54 inches) provide a sense of size, the weight (0.2 lbs) emphasizes the sensor's compact design, making it easy to integrate within the boiler system.
