Product Features
temperature control system
- The 7-inch large-screen touch intelligent PID temperature controller features self-tuning function that automatically optimizes PID parameters for different loads, eliminating manual adjustment and ensuring precise control.
- Built-in over-temperature alarm triggers instantly when the set limit is exceeded, protecting both the equipment and processed materials from thermal damage.
- It supports storage of up to 16 independent heating processes, each containing 31 editable temperature segments, allowing complex thermal profiles for annealing, sintering, and other multi-step cycles.
- Fully automatic operation enables the system to heat to target temperature, hold insulation for the preset duration, and stop automatically without manual intervention throughout the entire cycle.
- Real-time curve recording displays live heating data on the touch screen and stores historical data for later review, enabling users to track and compare each run's performance.
- Data can be exported anytime via USB interface, then viewed and printed on a computer as temperature data reports for quality documentation and traceability.
- Temperature control accuracy reaches ±1°C, meeting strict industrial and laboratory requirements for continuous constant temperature and precise ramp/soak control.
control
- Closed-loop control technology is adopted, including thyristor module trigger control, phase-shift trigger control or zero-crossing trigger method, enabling continuously adjustable output voltage, current or power.
- The system features constant voltage, constant current or constant power characteristics, providing stable and precise output for various heating applications.
- A dual-loop structure is designed with current loop as the inner loop and voltage loop as the outer loop, ensuring fast response and accurate regulation.
- When a sudden load is applied or load current exceeds the current limit, the output current of the voltage regulator is restricted within the rated range, protecting both the regulator and the load.
- The voltage loop actively participates in regulation, maintaining constant output current and voltage while keeping sufficient regulation margin for stable operation under varying conditions.
- This closed-loop design effectively protects heating elements from excessive current and voltage surges, achieving safe, reliable control and high control accuracy.
Application areas
- Application areas for precision heat treatment in metallurgy industry, including annealing, quenching and tempering of steel and alloy components requiring uniform temperature distribution.
- Application areas for ceramic sintering and glass processing where controlled heating and cooling rates are critical to prevent cracking and ensure product consistency.
- Application areas for laboratory research and material testing, supporting thermal cycling experiments, aging tests and calibration procedures with ±1°C accuracy.
