Leia atentamente este manual antes de usar o produto para garantir uma operação segura e eficiente.

2. Informações de segurança

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

3. Produto acabadoview e Componentes

The ASHCROFT 1009AWL Pressure Gauge is constructed for durability and accurate readings. Key components include:

• Discar: 2-1/2 inch diameter, clearly marked with 0-400 psi scale.
• Ponteiro: Indicates the measured pressure.
• Caso: Made from 304 Stainless Steel for corrosion resistance.
• Lente: Polycarbonate material for visibility and protection.
• Conexão: 1/4 inch MNPT (Male National Pipe Taper) located at the bottom of the gauge.
• Partes úmidas: Brass/Bronze construction ensures compatibility with various media.
• Enchimento líquido: Glycerin-filled for dampening pulsation and vibration, enhancing pointer stability and extending gauge life.

4. Instalação e configuração

1. Inspect Gauge: Before installation, visually inspect the gauge for any signs of damage. Do not install a damaged gauge.
2. Prepare Connection: Ensure the system connection point is clean and free of debris.
3. Aplicar selante: 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. Thread Gauge: Carefully thread the gauge into the system connection by hand until finger-tight.
5. Apertar: 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. Verificar Orientação: Ensure the gauge dial is oriented for easy reading.
7. Pressurização do sistema: Slowly pressurize the system and check for leaks at the connection point.

5. Operação

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

• Lendo o indicador: 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.
• Condições de operação: Ensure the operating environment and process media remain within the gauge's specified temperature range of -20°F to 150°F.
• Precisão: The gauge provides readings with an accuracy of +/-1.50% of full scale.
• Pulsação: The glycerin filling helps to dampen pointer fluctuation in systems with pulsation or vibration, providing a more stable reading.

6. Manutenção

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

• Inspeção de rotina: Periodically inspect the gauge for any physical damage, such as a cracked lens, bent pointer, or corroded case.
• Limpeza: Keep the gauge lens clean to ensure clear visibility of the dial. Use a soft, damp Pano para limpeza; evite produtos de limpeza abrasivos.
• Recalibração: 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. Solução De Problemas

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.
• Leitura Incorreta:
  • 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:
  • Despressurize o sistema.
  • 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.
