The difference between single-wire thermocouple quenching and ion induction quenching
Flame extinguishing protection device is that when the flame is extinguished, the gas stove can automatically cut off the protection function of the gas source. Flameout protection is one of the most common safety protection modes for gas stoves. There are two kinds of flameout protection modes on the market: single-wire thermocouple flameout and ion induction flameout.
The principle of single-wire thermocouple is based on the application of metal physical properties, which belongs to temperature difference induction. The extinguishing protection is controlled by temperature induction. The principle of ion induction is to apply the photoelectric property of flame, which requires electronic circuit to support operation, and no electricity is invalid; the ignition speed is fast, once the flame deviates from the induction needle, it will be cut off immediately. Comparatively speaking, the single-wire thermocouple has more stable service performance and longer service life.
