Vacuum furnace temperature control system using temperature control accuracy of 0.1 percent of the intelligent temperature control instruments, according to the product process curve preparation of computer control procedures to control the vacuum furnace temperature, insulation, cooling process, temperature control instrument operation, stop Automatic control by the PC to achieve the technical requirements of the process curve temperature control.
Temperature control system can be set to store a number of temperature control curve, each curve can be divided into multi-stage control, each temperature control curve with optional PID parameters, self-tuning function to ensure that no temperature rise, the system can Suitable for a variety of sub-degree thermocouple and pre-set temperature insulation curve.
The temperature controller output 4-20mA current signal to the trigger unit, the trigger unit to the current signal into a voltage signal, the output control excitation circuit DC voltage and current, thus controlling the magnetic voltage and current to ensure that the vacuum furnace according to the set curve Heating and heat preservation. The completion of temperature control, vacuum temperature sensing and control technology is one of the key technologies of vacuum heat treatment process and equipment. The process of using vacuum furnace must be well grasped.
