LEFOO LFM76 Explosion-Proof Differential Pressure Transmitter

Manufacturer describes this transmitter as explosion-protected; verify precise flameproof marking and approvals. This exact model identifier appears in LEFOO’s official download list.

Manufacturer: LEFOO

Manufacturer describes Ex-proof — certification document pending model check

Manufacturer title describes this series as explosion-proof. Do not treat the site’s CE file as independent ATEX or IECEx evidence. Confirm exact flameproof certificate and ordering code.

Document-type verification — not an ATEX certificate: The maker-hosted TÜV SÜD LFM76 / LFM77 / LFS71 / LFS72 certificate E8A 108521 0018 Rev. 00 is explicitly a voluntary 2014/30/EU electromagnetic-compatibility attestation against EN IEC 61000-6-1/-6-3. It is not an ATEX / IECEx approval, and the maker file itself says it does not replace the EU declaration of conformity. Although LEFOO markets this product as explosion-proof and shows Ex d IIC T6 Gb, an original, current Ex certificate with exact model/range/output, notified body and annex has not been verified. Confirm the actual delivered marking and approval before hazardous-location deployment.

LFM76 manufacturer-described explosion protection

LEFOO describes the LFM76 as explosion-protected, but product marketing text and a generic CE document are not sufficient for a claimed ATEX/IECEx installation. Obtain the precise certificate and nameplate, Ex protection method, gas/dust group, temperature class, approved cable glands, and control-loop parameters. The DP span, static overpressure limit and electrical output must separately match the installed process configuration.
