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 of the set time, along with an alarm prompt.

3. Temperature-sensing wire, Type K

Output: 3-32V

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

6. Heating Method: Uses a three-sided radiant heat method (left, right, and bottom sides).

7. Heating materials include: high-temperature stainless steel heating tubes.

8. Temperature Range: room temperature +30℃ to 250℃ (adjustable and controllable in between)

9. Control Accuracy: ±0.5℃

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 is sealed with a high-density silicone seal.

2. Vacuum Display Method: Vacuum gauge is used to indicate vacuum level.

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 continues this cycle to maintain a constant vacuum state.

4. Pressure Relief Method: After the test, manually activate the pressure relief function for pressure release; controlled by an electromagnetic valve.

5. Vacuum degree range of machine: ≤1.0×10^5 to 1.0×10^1 (Pa), [i.e., 10 Pa]

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

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

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

9. Vacuum Setting Method: The vacuum level can be freely set according to requirements, such as for a vacuum level of (100Pa), the gauge is set to (1.0 E 2), for a vacuum level of (10Pa), the gauge is set to (1.0 E 1), and so on. It employs upper and lower limits to control vacuum extraction and stoppage.

10. Vacuum Control Valve: Utilizing KF40 fitting high vacuum with pressure differential valve.

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

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