The temperature of the vacuum furnace control system
The temperature of the vacuum furnace control system
The vacuum furnace temperature control system and temperature control accuracy for zero point one percent of the intelligent temperature control instrument, computer control program control according to the product process curve of vacuum furnace heating, heat preservation, cooling process, the operation of the temperature control instrument, stop automatic control by a PC, implementation process technical requirements of temperature control curve.
Temperature control system can be set, the storage of multiple temperature control curve of each curve segment can be divided into control, temperature control of each curve with optional PID parameters, the tuning function, in order to assure heating without overshoot, the system can be suitable for a variety of dividing thermocouple and preset curve of heat insulation.
Temperature controller output 4-20 ma current signal to trigger unit, the trigger unit current signal into a voltage signal, the output control excitation circuit of dc voltage and current, so as to control the magnetic tuning voltage current, ensure set according to the curve of heating and heat preservation vacuum furnace. Complete temperature control, temperature sensing and control technology under vacuum is one of the key technologies of vacuum heat treatment technology and equipment, the use of vacuum furnace process must have a good master.
