OverviewLFT6800 is a compact digital display pressure transmitter featuring a high-performance ceramic or oil‑filled silicon sensing element, advanced signal processing and temperature compensation. It converts pressure into linear 4–20 mA, 0–10 V or RS‑485 signals and provides real‑time readout via a 4‑digit LCD head. The stainless steel enclosure and multiple pressure port options make it suitable for industrial installations measuring gases and liquids compatible with the wetted materials.
