Rosemount 5402AH1NA4SPVJAM1Q4 Radar Level Transmitter

Feature & Principle

It belongs to Rosemount 5400 series two-wire FMCW radar level transmitter. It emits microwave pulses to the liquid surface, calculates distance by measuring time-of-flight of reflected signal, and converts to liquid level value. Non-contact design avoids medium corrosion and fouling impact. It supports HART communication for remote configuration and device diagnostics, suitable for most liquid media. Built-in echo processing algorithm suppresses tank wall disturbance and foam interference.
