Advantages of Single-wire Thermocouple Flameout Protection Technology

Single-wire thermocouple extinguishing protection technology is more suitable for gas stoves (open environment combustion), and ion induction extinguishing protection technology is more suitable for gas water heaters (closed environment combustion). This is why major gas companies designate single-wire thermocouple extinguishing to protect gas stoves.

Single-wire thermocouple extinguishing protection technology is more suitable for gas stoves (open environment combustion), and ion induction extinguishing protection technology is more suitable for gas water heaters (closed environment combustion). This is why major gas companies designate single-wire thermocouple extinguishing to protect gas stoves. In fact, the vast majority of gas cooker manufacturers choose single-wire thermocouple extinguishing protection. The combustion environment of the cooker is open, and it is impossible to avoid the influence of external air flow (wind).

The single-wire thermocouple cuts off the gas source immediately when the temperature is lower than the specified temperature, which belongs to the instant reaction and the extinguishing time is about 9 seconds. The ionic induction type needs to extend the extinguishing time, which belongs to the delayed reflection. The actual extinguishing time is not 0.1 seconds, that is, about 0.1 seconds + 6 seconds = 6.1 seconds. In order to avoid the frequent occurrence of accidental extinguishing, some manufacturers must add an additional induction needle to double the induction effect and ensure at least one contact with the flame. Extend the protection time of extinguishing by using electronic circuit. Even if the two induction needles can not sense the flame at the same time, the gas will still output in the delay range as usual.
