Rosemount 5402 radar level transmitter for bulk solids

Click2Contact

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 unique 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 2-wire radar overcomes this by a signal processing algorithm that has been developed to address this specific challenge. For applications involving dry solids with low dielectric properties that create very 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.

Innovations such as Dual Port technology, which ensures a strong signal back to the transmitter, advanced surface tracking, and condensation-resistant antennas make the radar reliable, even in the most 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.

The radar 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.
