Foxboro SRI986-BIDS7ZZZNA Transmitter | Ultrasonic, Guided Wave Radar, 4-20mA+HART, 5m, 2"

Foxboro SRI986-BIDS7ZZZNA specifications. Ultrasonic/Guided Wave Radar hybrid level transmitter, 4-20mA+HART, 5m, 2" NPT.

Product Overview

The Foxboro SRI986-BIDS7ZZZNA is a hybrid level transmitter combining ultrasonic and guided wave radar (GWR) technologies, part of the Foxboro SRI986 series. Configured for a 5-meter range, it provides a 4-20mA output with HART communication and features a 2" NPT process connection. The device utilizes both non-contact ultrasonic and contact GWR measurements for enhanced reliability and diagnostics in challenging level applications for liquids and interfaces, even in presence of foam, vapor, or low dielectric media.
