LF3051T-GP/AP Smart Direct-Mount Pressure / Absolute Pressure Transmitter

The LF3051T-GP/AP monocrystalline silicon pressure transmitter is built around a single-crystal silicon sensor chip manufactured with advanced MEMS fabrication and precision production processes, delivering high accuracy and exceptional stability. An integrated smart signal processing module performs / integrates static-pressure and temperature compensation, maintaining reliable measurement accuracy and excellent long-term stability across wide ranges of static pressure and temperature variation. With ±0.05 % of span at reference conditions, 4–20 mA +HART output and a direct-mount design, the LF3051T is engineered for demanding process industries such as petrochemical, power generation and water treatment.

Applications

Oil&Gas, Chemical & Petrochemical
Used with a primary flow element (orifice plate or venturi tube) to provide accurate flow measurement, as well as pressure and level measurement for pipelines and storage tanks.

Power Plants & Gas Utilities
For pressure, flow and level measurement where high stability and high accuracy are essential.

Pulp & Paper
For furnace pressure and draft (negative pressure) measurement, and other applications requiring high stability and accuracy.

Steel, Non-ferrous Metals & Ceramics
For pressure, flow and level measurement in applications involving corrosive or chemically aggressive liquids.

Machinery & Shipbuilding
For applications where pressure, flow and level must be strictly controlled and stable measurement is critical.

Key Features

High Accuracy
High-precision monosilicon sensor chip; accuracy ≤ ±0.05 % of span.

High Overload Capability
Dual overload-protection diaphragm design; one-sided (unilateral) overpressure up to 40 MPa.

Excellent Environmental Adaptability
Intelligent static-pressure and temperature compensation eliminates the influence of temperature, static pressure and overpressure, minimizing the total measurement error under field conditions.

Excellent Long-Term Stability
Stability maintained within ±0.1 % FS over 3 years.

Flexible Remote Commissioning
Remote and local parameter setting and configuration via HART, FOUNDATION Fieldbus (FF), RS485 communication and the panel push-buttons.
