Autrol APT3100-D4M11F1S1-M1CPC2348A Differential Pressure Transmitter

Autrol APT3100-D4M11F1S1-M1CPC2348A is a Smart Differential Pressure Transmitter designed to deliver high-accuracy differential pressure measurements for process control, flow, and level applications. This two‑wire, loop‑powered device provides a 4–20 mA output with digital HART communication (Foundation Fieldbus optional) and is powered from 24 VDC with a load of 250–550 ohms. The transmitter supports differential pressure inputs with broad rangeability up to 100:1 and is specified for process temperatures from -40 to 120°C. It features a local LCD display for on‑site readings, self‑diagnostic functions, and zero/span/trim configuration, making setup straightforward. Rated IP66/67 and NEMA 4X, it is built for harsh environments and is certified for hazardous areas with approvals including ATEX, FM Ex d/Ex ia, and marine certifications (ABS, LR, DNV, etc.). Typical applications include measuring differential pressure for liquid, gas, or steam flows, as well as level and density measurements in oil & gas, chemical, water/wastewater, and power facilities. The APT3100 family emphasizes stability and repeatability, with accuracy around ±0.075% URL and long‑term stability, along with digital communication and self‑diagnostics that help reduce downtime.
