Hot runner temperature controller system's controll object is the manifold and the nozzle,it also effect the spure area.

Thermocouple is the elements to test the tempeature.,and transfer the signal to the temperature adjustment machine.Control heater execution manifold and nozzle of warming and thermal compensation.

The principle of thermocouple testing temperature:Thermoelectric effect.Thermoelectric power E will change and change because of the temperature which tested.Therefore use thermocouple temperature as sensitive components, he or she can get it generated thermoelectric potential as a temperature measurement information.Generally in industry,the distinguish of two material groups of thermocouple called dividing number.Like S、R、B、K、N、E、J,and etc with 16 kinds.The difference of thermocouple  dividing number, the thermoelectric power
would be show different.Reflect on the meter has a few degrees on temperature,do not complex the way of connection.

 

 

First of all, we must clear dividing number, can input to the corresponding temperature regulator. Second, the thermocouple lead wire have polarity, must by cable shading and marking, the alignment wiring.Attention to the thermocouple wire weak electric potential output millivolt and can not mixed with the power line in high voltage heater In addition, heat resistance is another kind of testing temperature element. It is based on metal conductor resistance will with temperature changes.For the moment,the heat resistance is less used in the hot runner technology.At present,The mould using thermocouple has put the two metal working ends after welding.

On the external heating manifold,the thermocouple is located between the heaters and the flow port.On the internal heating manifold,the thermocouple is usually installed in the Tube great type with the heater.

 

 

In Anole hot runner,there are are two types of thermocouple.K type and J type.They are just the difference in the connection of the temperature controller box.The function and the quality are the same.
