250KPa Y047 Gas Dead Weight Tester High Precision Air Pressure Balance For Pressure Calibration

Y047 Float Pressure Gauge – High Precision Air Pressure Balance for Accurate Calibration

Product Overview
The Y047 Float Pressure Gauge is a precision pneumatic load pressure gauge designed for use with compressed air or nitrogen as the pressure source. It employs a unique floating ball mechanism to ensure stable and accurate pressure readings, making it ideal for the calibration of various pressure instruments. The gauge offers a high degree of accuracy, and its automatic flow regulation ensures precise output pressure without requiring operator intervention.

Principles of Operation
The Y047 Float Pressure Gauge works by using compressed air or nitrogen to create pressure in the lower part of the sphere. This pressure, combined with a special weight on the top of the sphere, causes the float to lift and reach a stable position within the nozzle. The system achieves equilibrium when the weight's gravitational force balances with the air pressure force, producing a reliable and constant pressure output. The output pressure is proportional to the weight applied, ensuring high measurement accuracy.

Advantages

• Automatic Flow Regulation: The built-in automatic flow regulator adjusts to changes in weight, ensuring accurate output pressure without requiring manual adjustments.
• Continuous Stable Readings: The float remains suspended, providing continuous and stable pressure signals.
• Low Friction & High Resolution: The non-contact nature of the float and nozzle results in low friction, providing high resolution and excellent repeatability.
• Self-Cleaning Feature: The air flow helps to continuously clean the float during operation, ensuring long-term reliability and minimal maintenance.
• No Need for Operator Expertise: The system automatically adjusts, meaning accuracy is independent of the operator’s skill level.

Installation & Operation Guidelines

1. Placement: The gauge should be installed in an environment where the temperature is close to 20°C, humidity is between 10% and 75%, and free from vibrations and corrosive media.
2. Connection: Connect the float pressure gauge to the gas source and the device under test using the provided connection pipe. Ensure the knurled nut on the joint is tightly fastened to prevent leaks.
3. Operation: First, adjust the air source pressure, then open the air source and output valves. Place the weight on the float ball, and when the float rises, the gauge will output the pressure value corresponding to the weight. For calibration, adjust the weight on the frame as needed to achieve the desired pressure.

Maintenance & Care

• Cleaning: Regularly inspect and clean the float and nozzle to ensure accuracy. Use alcohol or carbon tetrachloride for cleaning, and dry them with a clean, soft cloth.
• Leak Detection: To check for leaks, close the output valve after applying weight and observe if the instrument under test retains its pressure.

Daily Maintenance Tips

• Ensure the gauge remains clean to avoid contamination affecting the accuracy.
• Check for leaks in the output connection pipeline to maintain consistent pressure readings.
