Electrical Testing for Quartz Tubes in Heating Devices

Quartz tubes, made from high-purity silicon dioxide, are a specialized form of industrial glass with exceptional physical and chemical properties. Due to their efficient heat-generating capabilities, they are commonly used in devices such as electric heaters, ovens, and other heating equipment.

Key Testing Methods for Quartz Tubes

1. Resistance Testing

Resistance testing helps determine whether a quartz tube is functioning properly.

• Equipment: Use a multimeter set to “continuity test” mode.
• Postupak:
  • Attach the red and black probes to each end of the quartz tube.
  • A properly functioning quartz tube should cause the multimeter’s buzzer to sound, with the needle pointing to zero, indicating continuity.
  • If there is no sound and the needle points to infinity, it suggests internal damage within the quartz tube.

2. Power Supply Voltage Testing

This test ensures that the quartz tube receives the correct voltage for optimal performance.

• Equipment: Set the multimeter to the “AC 250V” range.
• Postupak:
  • Place the probes at the power supply terminals of the quartz tube.
  • A reading close to 220V AC indicates that the power supply voltage is normal.
  • Deviations from this reading may signal issues with the power supply or the tube’s connections.

Handling and Maintenance Tips

Safe Handling

Quartz tubes are fragile and require careful handling:

• Always carry them gently to avoid breakage.
• Consider the tube’s coefficient of thermal expansion when used with other materials to prevent cracking or damage under heat.

Post-Use Cleaning

To maintain the quartz tube’s high purity and prolong its service life:

• Rinse with deionized water after use.
• Avoid direct hand contact after cleaning, as it may reduce the tube’s purity and impact its performance.
