Review WEIL-MCLAIN 12k Ohm Outdoor Air Sensor

The Weil-McLain 381-356-586 12k Air Sensor is a crucial component for ensuring optimal performance and efficiency in your heating system. This sensor is specifically designed for use with Weil-McLain gas and oil boilers, and it plays a vital role in monitoring the combustion process and maintaining the correct air-fuel ratio.

The 12k Air Sensor is an electro-pneumatic device that converts the electrical signal from the boiler's control into a pneumatic signal that actuates the draft diaphragm. This sensor continuously measures the air flow entering the burner and sends that information to the boiler's control system. Based on this data, the control system makes adjustments to the fuel input and combustion air flow to maintain the desired operating conditions.

This sensor is made of high-quality materials, ensuring durability and longevity. The sensor body is constructed of brass for superior corrosion resistance, while the diaphragm and other internal components are made of stainless steel to prevent rusting and wear. The sensor is also equipped with a protective cover that shields it from dirt and debris, helping to extend its lifespan.

Installing the Weil-McLain 381-356-586 12k Air Sensor is a straightforward process. It simply replaces the existing sensor on your boiler, and no additional wiring is required. The sensor comes with a clear instruction manual that outlines the steps for removal and installation.

In summary, the Weil-McLain 381-356-586 12k Air Sensor is an essential accessory for maintaining the optimal performance and efficiency of your heating system. Its durable construction, ease of installation, and ability to monitor and adjust the air-fuel ratio make it an invaluable addition to your boiler setup.
