LEFOO LFT2800 Oil-Filled Diffused Silicon Pressure Transmitter
Original LEFOO model-family technical profile. Manufacturer values refer to listed choices and must be matched to the exact selected order-code and source revision.
Maker-published specifications
| Sensor | Oil-filled silicon piezoresistive |
|---|---|
| Pressure range | Maker live page −100 kPa / as low as 1 kPa selectable to 60 MPa; published PDF revision has low endpoint 5 kPa. Verify suffix/revision. |
| Accuracy | ±1%, ±0.5%, ±0.25% FS dependent on span/range option |
| Signal | 4–20mA, 0.5–4.5 V, 0–5V, 0–10V, RS485 variant choices |
| Operating temperature | −20…+85°C; IP54 or IP65 by connector |
| Safety | Manufacturer lists an E explosion-protection selection but correct order code + ATEX/IECEx certificate not established |

Original manufacturer ordering codes and document reconciliation
LEFOO LFT2800 manufacturer datasheet issued as a 2026 upload describes a separate order-code field for each measurement range, output, pressure unit, accuracy, electrical connector, thread and cable length. Original published selection example: LFT2800 0-16 A4 B 1.0 D1 G 1.0 (this is a printed example, not a claim of current stock). Output: A4 = 4–20mA two-wire; V05 = 0.5–4.5V three-wire; V0 = 0–5V three-wire; V10 = 0–10V three-wire; RS = RS485 four-wire. Accuracy: 0.25, 0.5, 1.0 = % full scale, with allowable lower pressure span differing. Connector: D1 = DIN43650A; M = M12; C3/C4 = GX12; H = M12 four-core. Pressure threads: G/G2 = G1/4 or G1/2; N = NPT1/4; M20 = M20×1.5; R = R1/4; U = 7/16–20 UNF.
Document revision conflict: Original LEFOO 2026-02-12 file and live model website specify minimum selectable range starting at 1 kPa for certain ±1% options, with ±0.5% at 3 kPa and ±0.25% at 10 kPa. Original 2026-01-29 model file describes the earlier 5 kPa minimum family. The correct device tolerance depends on original order-code and actual maker revision; do not select the smallest universal range or best accuracy for every unit.
Safety: A maker marketing phrase “explosion-proof type E” and TÜV SÜD E8A 108521 0005 Rev.00 EMC sample attestation do not establish ATEX or IECEx certification for an LFT2800 order code. An exact certificate, certificate issue and operating conditions remain open.
LFT2800 — pressure range source discrepancy
LEFOO’s LFT2800 live catalog and a published PDF disagree over the low end of the family pressure-range offering; do not silently select one endpoint as universal. Specify the actual oil-filled silicon cell, working pressure, connector ingress protection and ±0.25/0.5/1% full-scale accuracy option. Analog versus RS485 versions have different host interfaces; a maker-stated E safety option is not an independently verified ATEX/IECEx certificate.
