LFT2100 — ceramic pressure sensor accuracy by span
LFT2100 uses a ceramic pressure element with model-specific voltage or loop output options. The maker’s quoted ±0.5% FS applies to selected pressure ranges above 0.3 MPa, whereas other selections have different error figures. Review pressure reference, liquid wetted seals, connector option and overpressure margin before substitution. A4 4–20 mA and V05 0.5–4.5 V need different host wiring and supply; the latter is a ratiometric 5 V design, not an industrial current loop.
