2. Maklumat Keselamatan

• Had Tekanan: Do not exceed the maximum rated pressure of 400 psi. Over-pressurization can cause gauge failure and potential injury.
• Pemasangan: Ensure the gauge is installed by qualified personnel using appropriate tools and sealing methods.
• Keserasian Sistem: Verify that the gauge's wetted parts (Brass/Bronze) are compatible with the process media to prevent corrosion or damage.
• Had Suhu: Operate the gauge within the specified temperature range of -20°F to 150°F. Extreme temperatures can affect accuracy and lifespan.
• Pengendalian: Avoid dropping or subjecting the gauge to severe impact, as this can damage internal components.

4. Pemasangan dan Persediaan

1. Inspect Gauge: Before installation, visually inspect the gauge for any signs of damage. Do not install a damaged gauge.
2. Sediakan Sambungan: Ensure the system connection point is clean and free of debris.
3. Sapukan Sealant: Apply an appropriate thread sealant (e.g., PTFE tape or pipe dope) to the 1/4 inch MNPT threads of the gauge connection. Ensure sealant does not enter the gauge or system.
4. Tolok Benang: Carefully thread the gauge into the system connection by hand until finger-tight.
5. Ketatkan: Using a wrench on the wrench flats of the gauge connection (not the case), tighten the gauge until secure. Avoid over-tightening, which can damage the threads or the gauge.
6. Sahkan Orientasi: Ensure the gauge dial is oriented for easy reading.
7. System Pressurization: Slowly pressurize the system and check for leaks at the connection point.

5. Operasi

The ASHCROFT 1009AWL Pressure Gauge is designed for straightforward operation. Once properly installed, the gauge will continuously display the system pressure.

• Membaca Tolok: Observe the pointer's position on the dial. The primary scale is in psi (pounds per square inch), ranging from 0 to 400. The smallest graduation is 10 psi.
• Keadaan Operasi: Ensure the operating environment and process media remain within the gauge's specified temperature range of -20°F to 150°F.
• Ketepatan: The gauge provides readings with an accuracy of +/-1.50% of full scale.
• Denyutan: The glycerin filling helps to dampen pointer fluctuation in systems with pulsation or vibration, providing a more stable reading.

6. Penyelenggaraan

Regular maintenance ensures the longevity and accuracy of your pressure gauge.

• Pemeriksaan rutin: Periodically inspect the gauge for any physical damage, such as a cracked lens, bent pointer, or corroded case.
• Kebersihan: Keep the gauge lens clean to ensure clear visibility of the dial. Use a soft, damp kain untuk membersihkan; elakkan pembersih yang kasar.
• Penentukuran semula: While ASHCROFT gauges are built for accuracy, prolonged use or exposure to harsh conditions may necessitate recalibration. Consult a qualified technician for recalibration services if accuracy is critical and suspected to be compromised.
• Liquid Fill: The glycerin fill is sealed. If the liquid level appears significantly low or cloudy, the gauge may require replacement or professional servicing.

7. Penyelesaian masalah

Below are common issues and potential solutions for the ASHCROFT 1009AWL Pressure Gauge:

• No Reading / Pointer Stuck:
  • Verify that the system is pressurized.
  • Check for blockages in the connection line to the gauge.
  • Inspect for physical damage to the gauge.
• Inaccurate Reading:
  • Ensure the gauge is operating within its specified temperature range.
  • Confirm the gauge's range is appropriate for the system pressure.
  • Consider professional recalibration if accuracy is critical and other factors are ruled out.
• Leak at Connection:
  • Kurangkan tekanan sistem.
  • Re-apply thread sealant and re-tighten the connection.
  • Inspect threads for damage.
• Liquid Fill Discoloration/Loss:
  • This may indicate a seal compromise or internal issue. The gauge may need replacement.
