LEFOO LFT710 Monocrystalline Silicon Differential Pressure Transmitter

LEFOO LFT710 Monocrystalline Silicon Differential Pressure Transmitter. Technical family profile based on the original manufacturer’s current model description; options and approvals must be verified against the exact ordered suffix and delivered nameplate.

Manufacturer specifications

PrincipleMonocrystalline silicon MEMS differential pressure transmitter for process gases and liquids
Range choicesMaker product table includes 6 kPa, 40 kPa, 250 kPa, 1 MPa and 3 MPa reference pressure ranges; actual span and static rating model-dependent
Accuracy±0.075% FS manufacturer-listed family figure
Signal4–20 mA, HART and RS485 alternatives, 12–36 VDC
Pressure protection10, 16 or 25 MPa static-pressure configurations; stated one-side overload varies by document/variant
Ex evidenceManufacturer lists ExdIICT6; current ATEX/IECEx certificate issue and option schedule not independently verified
Photo / Ex approval verification: No independently selected and model-matched original manufacturer image has been attached to this AirAlign page. For hazardous area claims, original ATEX/IECEx certificate numbers and scope must be established for the ordered model. General CE/EMC conformity is not an explosion protection approval. Model-level evidence only; SKU and original image QA open.

LFT710 — DP manifold and loop configuration

LFT710 is the differential-pressure companion to LFT700; it requires high/low process connections and a suitable 3/5-valve manifold or equivalent isolation where the application demands it. A 6 kPa cell and a 3 MPa family cell have different useful DP resolutions, so select range and static pressure separately. Commission zero/equalization and the exact 4–20 mA/HART or RS485 interface. Manufacturer literature’s model-family certification must be checked against the purchased enclosure and diaphragm configuration.

Original manufacturer ordering table: explosion-protection selection (23 October 2026)

The original LEFOO LFT710 ordering table lists a separate Code 9 — Explosion-proof grade with option N = ordinary, not explosion-proof, D = manufacturer-described flameproof Ex d IIC T6, and I = manufacturer-described intrinsic safety Ex ia IIC T6. These ordering-code distinctions are not interchangeable and the Ex statements are supplier declarations, not independently validated ATEX/IECEx certificates. A delivered model with Code 9 = N must never be presented as approved for a hazardous area because the family brochure also lists an Ex option.

The same original selection table gives static pressure options A = 10 MPa, B = 16 MPa and C = 20 MPa, and accuracy selections 2 = 0.2, 5 = 0.5, 7 = 0.075, 6 = 0.065 and 8 = 0.05. These are model selectable accuracy options, not a promise that all options can be ordered with all pressure ranges. The manufacturer’s legacy group product page mentions IP66 / 0.05% accuracy whereas the current branded LFT710 product page specifies IP65 / 0.075% FS; source revision and final ordered configuration must govern.
