Manufacturer identifies ATEX and EAC options for hygienic washdown duty. Listed measuring range 100 mbar–25 bar, accuracy to ±0.10% FS, −25 to +85°C operating ambient and −25 to +100°C process temperature. ATEX model approval does not by itself establish IECEx coverage or universal zone/T-class approval.

Technical documentation

Official STS ATM/F/Ex technical catalog.

Hazardous-area verification: ATEX, IECEx, FM and EAC approvals are not interchangeable. Confirm actual order-code suffix and manufacturer certificate schedule before installation.

ATM/F/Ex hygienic hazardous-area integration

Hygienic process design and explosion protection are different acceptance criteria. Confirm the exact flush diaphragm connection, wetted materials, clean-in-place temperature and process seal for the food or chemical application, then review the order-specific ATEX/EAC approvals for the surrounding classified area. The listed 100 mbar–25 bar range and ±0.1% FS option are family values and need ordered-span verification; ambient and process temperature limits may also differ. The current page photographs the ordinary ATM/F family, not a nameplate-identifiable /Ex assembly, so its illustration cannot substantiate zone, group, gas or temperature class. Do not infer IECEx solely from an ATEX listing.
