Product Overview
The Foxboro IGP10‑T22F1F is a smart two‑wire gauge pressure transmitter within the I/A‑Series instrumentation platform. It converts process gauge pressure into standard 4‑20 mA analog signal superimposed with HART digital protocol, supporting remote configuration, diagnostic access and real‑time process data reading. Built‑in silicon strain‑gauge sensing capsule delivers stable measurement performance for heavy‑duty industrial environments. Widely used as replacement spare for legacy DCS‑based process plants, suitable for retrofitting and maintenance of existing measurement loops.
Series
IGP10 series is Foxboro’s intelligent direct‑mount gauge pressure transmitter family. It supports multiple output options including HART, FOUNDATION Fieldbus and FoxCom. Different code variants cover broad pressure span ranges, various process connections, wetted material selections and hazardous‑area certifications.

Function
IGP10‑T22F1F senses process gauge pressure through the pressure capsule. It converts physical pressure value into standardized 4‑20 mA loop current for DCS or PLC input. HART digital signal enables remote modification of range, damping and tag parameters, reading of device status and fault diagnostics. The transmitter provides stable measurement output under fluctuating process pressure and temperature conditions, supporting closed‑loop process control and site‑wide asset management.
Purpose
Measure gauge pressure of liquid, gas and steam in industrial process loops. Deliver accurate pressure feedback to control systems. Deployed for new spare‑part replacement and field retrofitting of existing Foxboro I/A‑Series instrumentation systems.
Application Fields
Oil & gas production, refineries, chemical processing plants, power generation, pulp‑and‑paper mills, water‑wastewater treatment, petrochemical facilities, legacy DCS site maintenance and instrumentation upgrade projects.
