Ex evidenceMaker site lists ExdIICT6 and offers ATEX document; actual issue number, annex and ordered variant have not been independently checked
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.

LFT700 — HART and RS485 are separate choices

LEFOO’s LFT700 lists monocrystalline MEMS pressure sensing, ±0.075% FS nominal precision and multiple nominal pressure-cell ranges. The maker offers 4–20 mA, 4–20 mA HART and RS485 configurations, so the host must match the ordered electrical version rather than expecting them all concurrently. Record the configured sensor span, 100:1 turndown context and actual process fitting, and verify the Exd IIC T6 claim only against the specific approved order code and certificate.
