How to avoid the failure of the internal system of the electric heater

The internal system disconnection fault monitoring and control device of the electric heater is connected between the electric heater and the electric heater in the temperature control instrument contact, and the electric current is mainly used for electric current heater breaking (burning) current detection and electric heater internal instrument Voltage detection of the switch point on and off.

If the electric heater is normally turned on and off, the device in the electric heater has no effect normally, but it will cause no signal output in the electric heater; only when the electric heater has an open circuit failure of the electric heater internal system, The device in the electric heater has a signal output, and then cooperates with devices (display, buzzer, host control, etc.) in other electric heaters to realize the electric heater control function requirements.
