YWD Series Dual Piston Pressure Gauge – High Precision Oil-Based Self-Weight Tester for Pressure Calibration

Product Application: The YWD Dual Piston Pressure Gauge is primarily used for calibrating pressure sensors, pressure transmitters, digital pressure gauges, and other precision pressure instruments. It can also be used to calibrate mercury manometers, various non-corrosive industrial pressure gauges, or other types of precision pressure measurement instruments.

The main advantages are its wide measurement range, large measurement capacity, and the ability to use a single set of weights, which helps reduce procurement costs. This model is widely applicable in industries such as petroleum, chemicals, metallurgy, coal mining, shipbuilding, instrumentation, and other industrial enterprises.

Product Features:

• Each weight comes with an adjustable cavity for easy periodic inspection and adjustment.
• Each piston is equipped with a protective breakage device, ensuring safe use for the user.
• Weights are designed with a hanging basket structure for low center of gravity and excellent stability.
• Equipped with quick pressure connectors to eliminate the risk of oil leakage.
• Every unit comes with a legal metrological certificate (CNAS).
