Switch/monitor is designed for airflow safety-related applications

Built for industrial-grade ovens and furnaces, the FCI FS10i airflow switch/monitor meets the requirements of the National Fire Prevention Association Standard 86 and is SIL 2 rated for safety instrumented systems. The unit provides relay output or low-flow trip point detection and a continuous 4-20mA flow monitoring output. It includes a top-/front-mounted 10-LED array that provides a visual indication the trip point has been exceeded and of relative flow rate across the flow range. Operating over a flow range from 0.25 fps to 400 fps, the flow switch/monitor has a repeatability of 0.5 percent of reading.
