Features:
1.Cylinder structure is adopted for high temperature furnace, heating resistance wire, resistance wire distribution is reasonable, to ensure that the furnace temperature gradient and volatility resistance wire adopts three control mode, respectively Furnace wire 1.5 mm in diameter. (if you need to work long hours, lasting and creep test, can use the 5 mm diameter thick silk as heating body furnace, low voltage, high current power supply, greatly extend the life of the furnace silk, can work continuously for 5000 hours.)
2.Temperature measuring device is K type thermocouple, stable and reliable to work long hours, measurement accuracy satisfies the requirement of national standard and the line mark.
3. Electric furnace with special heat insulation measures, the external surface of the furnace temperature rise is small, energy saving and safe.
2.Temperature control measurement system
It is composed by temperature measurement component, central computing unit (PLC), temperature detection instrumentation (PID adjust, with AT function) and HIM, etc
Real time monitoring temperature data vibration, display curve, and record of curve and invoking function; Human set the abnormal data; Add short message sending module, send a police report to the standard mobile phone
3. Connection with testing machine
High temperature furnace test unit through the rotating arm which is installed on the mobile trolley column, folding arm can be adjusted according to request any height and horizontal position, and can lock after positioning.
The normal temperature test, furnace body can be removed lightly.
4. Sample clamping
Sample followed by high temperature jig, watercooling connecting rod on both ends. Only has the cooling function connecting part with the sensor
Testing machine wedge specimen jig can directly connecting with the rod .Also can be directly connected to connection accessories and the moving beam of testing machine
