The IDP05S is Schneider Electric's value-tier differential pressure transmitter - a piezoresistive silicon cell in a welded stainless cavity that delivers dependable DP measurement for flow, level, and filter monitoring.

Why pay for the 05S instead of the 10S?

The IDP10S adds FoxCal multi-curve accuracy and FOUNDATION Fieldbus; the IDP05S keeps it simple at ±0.075% span with HART and still carries SIL 2 - the right call where the loop does not need eleven calibration curves. The alternative - the 10S - spends budget on accuracy the application never uses.

What jobs does it actually do?

Square-root extraction turns it into an orifice-plate flow meter, while the same cell reads pressurized-tank level, filter differential, or pump efficiency, with 316L wetted parts in an IP66/IP67, ATEX-approved housing. The alternative - a single-purpose meter - covers one of those jobs.

How stable over the years?

Drift stays under ±0.05% URL per year with a 5-year warranty, so recalibration intervals stretch and spare-part inventory stays small. The alternative - an analog cell - offers no drift trend to plan around.
