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.

LFT2021 — hygienic diaphragm and CIP boundary

LFT2021’s electropolished 316L hygienic diaphragm is relevant where process cleanability and media contamination matter. Choose the actual vacuum-to-positive pressure span, cleaning temperature and gasket/port design together; the cited 150°C medium capability is not the transmitter electronics’ ambient limit. Confirm whether the supplied output is current, voltage or digital and whether any pressure/temperature seal supports repeated SIP cycles.
