Product Description

Detail Information

Product Description

The LF3051T-GT/AT single-flange process pressure transmitter uses an advanced MEMS single-crystal silicon sensor chip. Its modular design and precision manufacturing deliver high accuracy and exceptional long-term stability. The integrated intelligent signal-processing module performs temperature and pressure compensation, ensuring stable measurement over wide ranges of process temperature and pressure variation.

The LF3051T-GT/AT measures the gauge or absolute pressure of liquids, gases and steam and provides a two-wire 4–20 mA DC output with HART communication. In addition to HART, PROFIBUS PA, RS-485 (Modbus RTU) and FOUNDATION Fieldbus are available.

Applications

Oil & Gas, Chemical & Petrochemical
Accurate flow measurement when combined with a primary flow element; pressure and level measurement for pipelines and storage tanks.

Power Generation & Gas Utilities
High-stability, high-accuracy measurement of pressure, flow and level.

Pulp & Paper
Furnace draft (slightly negative pressure) measurement requiring high stability and repeatability.

Steel, Non-Ferrous Metals & Ceramics
Pressure, flow and level measurement in corrosive or aggressive media service; diaphragm seals available in 316L, Hastelloy C-276 and tantalum.

Machinery & Shipbuilding
Stable pressure, flow and level measurement where tight process control is required.

Key Benefits

High Accuracy — ±0.05 % of span
Advanced monosilicon sensor chip delivers reference accuracy of ±0.05 % of span.

High Overpressure Capability — up to 40 MPa
Dual overload-protection diaphragms withstand one-sided overpressure up to 40 MPa.

Excellent Environmental Adaptability
Intelligent temperature and static-pressure compensation offsets the effects of temperature, static pressure and overpressure, minimizing total measurement error in the field.

Outstanding Long-Term Stability — ±0.25 % FS over 3 years
Performance remains within ±0.25 % FS over three years of operation.

Flexible Remote Configuration & Commissioning
Configure and commission locally or remotely via HART, FOUNDATION Fieldbus and RS-485 (Modbus RTU), or with the panel push-buttons.
