Description
The factory is specialized in the manufactury, research of the safety protection facilities for burning appliances such as Magnet Unit, Thermocouple, Millivolt Power Generator and other magnet control units.

The matched application of the thermocouple and magnet unit makes up of the protection device for ensuring the flameout safety of the burning appliance. Thermocouple is a sensing element that may provide micro-power. The magnet unit is a control element. When its top end is heated by flame, thermo-electrical potential is generated by temperature difference between the cold and hot ends and a closed loop current is formed. The solenold valve under the combined action of outside force and magnetic field actuation is in the attracted state and the passage of fuel gas is open. When the flame is out, the temperature at the top end of the thermocouple is lowered, and the thermo-electrical potential and current gradually reduce. The magnet unit resets under the action of compressed spring and the passage of fuel gas is closed. Thus the safety protection function is achieved.
Technical Characteristics
1. Type of conection to magnet unit: Nut, Coaxial, Faston

2. Lengths: 170-1850mm

3. Maximun temperature (head): Depending on the head type, up to 700°C maximun.

4. xxxxx in open circult: ≥30mV(Normal) ≥16mv(Fast action)

5. Inner resistance: 8.5+0.22*L(mΩ)

Install with the protection request
1. The maximun torque of the thermocouple connected with thread under the installation function should not exceed 5 xxxxx
2. All parts in contact or connection with the magnet unit components should be separated from dust, oil stain and metal scraps to avoid from block in current inside the circuit.
3. The bend radius of the tubular mode thermocouple should not be less than 20 mm. Two-wire system thermocouple should have a minimum radius of 5 mm. These two types of thermocouple should avoid from fricition or contact with sharppointed objects in installation.
