Foxboro IAP05S Absolute Pressure Transmitter

IAP05S Pressure Transmitter

The Foxboro IAP05S is a cost-effective, intelligent absolute pressure transmitter designed for industrial applications that require dependable performance, digital diagnostics, and compatibility with modern control systems—all at a lower price point than high-end instrumentation. Part of Schneider Electric’s S Series “Value” family, the IAP05S offers essential features such as 4–20 mA output with HART® communication, SIL 2 safety certification, and rugged mechanical design. It strikes a balance between reliability, functionality, and affordability, making it ideal for facilities standardizing on smart instrumentation without the need for ultra-high accuracy or advanced multi-calibration features found in premium models like the IAP10S or IAP50S.

At its core, the IAP05S measures absolute pressure, meaning it references pressure against a perfect vacuum rather than atmospheric pressure. This is especially important for processes where vacuum conditions, sealed systems, or ambient variability would make gauge pressure unreliable. With an accuracy of ±0.075% of span and a turndown ratio up to 400:1, the IAP05S supports a wide range of applications from low to high absolute pressure conditions—making it a flexible tool for engineers trying to reduce spare parts inventory or simplify transmitter selection. Its long-term stability (<±0.05% URL/year over 5 years) ensures reliable, repeatable measurements over time, minimizing the need for frequent recalibration and maintenance interventions.
