Rosemount 3102HA1FRCNA Ultrasonic Level Transmitter

Rosemount 3102HA1FRCNA is a Rosemount 3100 Series Ultrasonic Level Transmitter designed for reliable, non-contact liquid level measurement in tanks and vessels. It is powered from 12 to 30 VDC and provides a 4-20 mA current output with HART communication for two-way digital diagnostics, while the model’s two integral relays offer local alarm or control functionality. The transmitter features a 14 NPT conduit connection and a 2-inch process connection, aligning with common industrial fittings, and is built for harsh industrial environments. As part of Emerson’s Rosemount 3100 family, the 3102 variant emphasizes ultrasonic level sensing and includes two relays to support basic automation tasks, making it suitable for continuous level monitoring with remote monitoring capabilities via HART.
