3. Поставување и инсталација

Proper installation is crucial for accurate readings and the longevity of the WIKA 732.26 Differential Pressure Gauge. It is recommended that installation be performed by qualified personnel.

1. Отпакување: Carefully remove the gauge from its packaging. Inspect for any visible damage that may have occurred during transit. Do not use if damaged.
2. Монтирање: The gauge should be mounted in a location where it is easily accessible for reading and maintenance, and protected from excessive vibration, temperature fluctuations, and direct sunlight. Ensure the mounting surface is stable and secure.
3. Процесна врска: Connect the gauge to the process lines using appropriate fittings. Ensure all connections are tight to prevent leaks. Refer to the specific connection type of your gauge model for proper fitting selection.
4. Pressure Equalization: Before applying differential pressure, ensure that both high and low pressure ports are open to the same pressure or are properly vented to atmosphere to prevent damage from sudden pressure surges.
5. Системска интеграција: Integrate the gauge into your system according to your specific application requirements. Ensure that the pressure limits of the gauge (0-100"WC) are not exceeded.

Внимание: Exceeding the maximum static or overpressure safe limit (500 psi) can cause permanent damage to the gauge and may lead to system failure or injury.

4. Упатства за работа

The WIKA 732.26 Differential Pressure Gauge provides a clear analog display for differential pressure readings.

1. Understanding the Dial: The gauge dial is marked from 0 to 100 in.H2O (inches of water column). The needle indicates the current differential pressure.
2. Примена на притисок: Once installed, apply the differential pressure across the high and low ports. The gauge will respond by moving the needle to the corresponding pressure value.
3. Читање на мерачот: Read the value indicated by the tip of the needle on the scale. For optimal accuracy, read the gauge directly from the front to avoid parallax error.
4. Нормално работење: During normal operation, monitor the gauge regularly to ensure the system is functioning within desired pressure parameters.

Забелешка: The gauge is marked "US NO OIL," indicating it is suitable for applications where oil-free measurement is required or preferred.

5. Одржување

Regular maintenance ensures the continued accuracy and reliability of your WIKA differential pressure gauge.

• Чистење: Clean the acrylic lens and stainless steel case with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the materials.
• Инспекција: Periodically inspect the gauge for any signs of physical damage, corrosion, or leaks at the connections.
• Калибрација: While the gauge is factory calibrated, periodic re-calibration by a qualified technician may be necessary depending on application requirements and industry standards.
• Складирање: If storing the gauge, ensure it is kept in a clean, dry environment within its specified temperature range.

6 Смена на проблеми

This section addresses common issues you might encounter with your differential pressure gauge.

• Нема отчитување или е неточно отчитување:
  • Check if the gauge is properly connected to both high and low pressure ports.
  • Ensure there is actual differential pressure being applied.
  • Verify that the pressure range of the gauge matches the expected process pressure.
  • Inspect for blockages in the pressure lines leading to the gauge.
• Gauge Needle Fluctuates Excessively:
  • This may indicate pulsations in the process pressure. Consider installing a snubber or dampener if not already present.
  • Check for vibrations in the mounting location.
• Visible Damage or Leaks:
  • If the gauge casing or lens is cracked, or if leaks are detected at the connections, the gauge may need to be replaced or professionally repaired. Do not attempt to repair internal components.

For issues not covered here, or for complex problems, contact WIKA technical support or a certified instrument technician.
