In this post I would like to share some random notes on flame sensor rods. My hope is you will find this post interesting… In principle we can use a regular infrared diode or phototransistor to sense ...

This method is usually known as “flame rectification.” Many servicers believe the flame sensor takes an active role in proving flame, and because of this, believe the sensors sometimes fail. Let’s ...

The sensor allows the pilot light to be automatically re-ignited if the flame is no longer present. The circuit is a surprisingly simple one, with a PNP transistor being turned on by the flame ...

The FS-2000 flame sensor from Takex is a UL-rated UV Flame detector for schools, server rooms or other critical environments where early detection of flame presence is essential to an effective ...

The FS-5000E Flame Sensor from Takex immediately detects ultraviolet rays contained in flames and activates an external output. With faster detection than conventional smoke alarms, they are ideal ...

Step 5: Unscrew the flame sensor mounting bracket screw and gently pull the sensor out from inside the furnace. Step 6: Check the porcelain base of the sensor for cracks or chips.
