Emerson Process Management has released a version of its Rosemount 5400 series of non-contacting radar level transmitters aimed specifically at demanding bulk solids level measurement applications. The Rosemount 5402 high-frequency 2-wire radar uses Rosemount Radar Master software and algorithms to overcome the specific challenges of solids level measurement in vessels, bins and silos, such as inclining or sloping surfaces, low dielectric properties and high filling rates.

Inclining or sloping surfaces deflect energy away from the radar and can generate several small reflections. The product’s signal processing algorithm has been developed to address this specific challenge. For applications involving dry solids with low dielectric properties that create low reflections and thereby can result in an unstable level measurement, sensitivity is increased, noise cancelled out and echo strength increased. The measurement difficulties caused by high filling rates are met by increased sensitivity and echo traceability.

The 2-wire technology enables fast installation by taking advantage of existing cabling, while still providing the same high levels of data and diagnostics that would normally require 4-wire connections. Innovations such as Dual Port Technology, which ensures a strong signal back to the transmitter, advanced surface tracking and condensation-resistant antennas make the product suitable for even demanding applications.

User-friendly graphical interfaces with wizards and suggestions for application-specific configuration help users easily integrate the transmitter into new or existing control systems. This, in addition to reduced maintenance operation and advanced diagnostics, results in overall improved uptime and enhanced safety.

The product offers connectivity to a range of communications protocols including HART, Foundation fieldbus, FISCO and Modbus. The device has ATEX, IECEx, FM, CSA, CRN, Inmetro, DIBt, GOST and NEPSI approvals.
