Flange-Mounted Differential Pressure Transmitter with 4–20 mA + HART Output
Industrial-grade flange-mounted differential pressure transmitter designed for accurate measurement of liquid level, flow, and process pressure. Features a high-precision MEMS silicon sensor, HART communication, and a backlit display — ideal for liquids, gases, and steam applications.
The Flange-Mounted Differential Pressure Transmitter is designed for precise and reliable measurement of liquid level, flow, and process pressure in industrial applications.
Built from the same high-performance foundation as the LFT710 differential pressure series, this model incorporates a welded liquid-level flange filled with silicone oil or inert transfer fluid. This design ensures accurate pressure transmission while isolating the sensing element from direct contact with the process medium — protecting it from crystallisation, solidification, condensation, or vaporisation effects that can affect measurement stability.
The device converts differential pressure into a standard 4–20 mA output with HART communication, allowing easy connection to PLCs, DCS, or SCADA systems. It supports remote configuration and diagnostics via HART 375/475 communicators and includes a high-brightness LCD display for clear local indication of measured values.
With its MEMS monocrystalline silicon sensor, robust construction, and high measurement accuracy, this transmitter is ideally suited for tank level monitoring, steam systems, flow measurement, and pressurised process applications.
