Section 3: High-Temperature Test Chamber Temperature Control System

1. The temperature controller is a digital display gauge, featuring single-point temperature control, automatic calculation, simultaneous display of PV/SV, and key setting.

2. Timer Function: Equipped with an Omron timer, heating and vacuum extraction will stop upon completion, along with an alarm alert.

3. Temperature-sensing wire, Type K.

4. Output: 3-32V

5. The current controller is a PID + SSR solid-state relay.

6. Heating Method: Utilizes three-sided radiant heating (left, right, and bottom sides).

10. Display Accuracy: 0.1℃

11. Internal Temperature Deviation: ±5.0℃ (no vacuum, unloaded test)

4. High-Temperature Test Chamber Vacuum System:

1. Door sealing method: The machine door uses a high-density silicone sealing strip for sealing.

2. Vacuum Display Method: Vacuum gauge for vacuum level indication.

3. The vacuum control method is: automatic control. The vacuum pump stops working when the vacuum reaches the set value, automatically replenishes vacuum when it falls below the upper limit, and operates in this cycle to maintain a constant vacuum state.

4. Pressure relief method: After testing, manually initiate the pressure relief function for pressure release, controlled by an electromagnetic valve.

5. Machine vacuum range: ≤1.0×10^5 ~ 1.0×10^1 (Pa), [i.e., 10 Pa]

6. Vacuum Preservation Pressure Leak Rate: 0.01 Pa/L per second

7. Vacuum Tube: Made with stainless steel vacuum corrugated tube.

8. Vacuum Sensor: Utilizing KF16 vacuum resistance gauge tube.

9. Vacuum Setting Method: The vacuum level can be freely set according to requirements, such as for a vacuum of (100Pa), the gauge setting is (1.0 E 2), for a vacuum of (10Pa), the gauge setting is (1.0 E 1), and so on. The vacuum and stop vacuum processes are controlled using upper and lower limits.

10. Vacuum Control Valve: Equipped with KF40 connection, high vacuum with pressure difference valve for filling gas.

11. Vacuum Pump Configuration: Double-stage direct-connected oil pump used.

12. Vacuum Degree Display: Utilizes a resistance vacuum gauge to display the vacuum level, with the display in scientific notation.
