Key Features & Advantages

High Accuracy & Stability: Offers exceptional measurement accuracy up to ±0.075% and excellent long-term stability of ±0.1% over three years, ensuring consistent and reliable data.

Robust & Versatile: Built to withstand harsh conditions with a wide operating temperature range, high IP67 enclosure rating, and multiple explosion-proof certifications.

Flexible Configuration: Zero and span can be adjusted arbitrarily within the measuring range. Users can select between linear or square root output and adjust damping time to suit specific application needs.

Intelligent Communication: Features 4-20 mA output with superimposed HART protocol for easy remote configuration, calibration, and diagnostics.

Quick Start-up: Fast pre-heating time of less than 15 seconds allows for rapid system commissioning.


Typical Applications

The YD3051 is ideal for various industrial sectors, including:

Process Industries: Flow measurement (orifice plates, venturi tubes), level measurement in tanks and vessels, and filter monitoring.

Water & Wastewater Treatment: Monitoring pump performance, filter clogging, and differential pressure across valves.

HVAC Systems: Measuring air and liquid flow rates for energy management and control.

Power Generation: Monitoring critical pressure differentials in boilers, turbines, and filtration systems.
