Ferroli 39809190 Xignal NTC Temperature Sensor

The Ferroli NTC Sensor is a thermo-electronic component that changes its resistance (measured in ohms) when the temperature it detects changes. The resistance that is measured across the 2 pins of this sensor is measured in 1000?s of ohms. The hotter the temperature the less resistance there is across the two pins. The resistance across these two pins is constantly being measured by the printed circuit board within the boiler and these resistances directly effects the amount of gas that is transferred to the burner. The higher the resistance the more gas that is required, the lower the resistance the less gas that is required.

Most Ferroli sensors don?t come with their sealing washer and if fitted without one may leak, below we may have displayed a sealing washer to purchase if you require one.
