Operating principle

Rosemount 4390 Series of Corrosion and Erosion Wireless Transmitters is an Emerson™ wireless product and uses the same radio and power modules as other Emerson wireless products. The corrosion and erosion transmitter communicates through standard wireless Gateways. The gateways interface with existing host systems using industry standard protocols including OPC, Modbus TCP/IP, and Modbus RTU.

A. AMS Suite B. Plantweb™ Insight Inline Corrosion Application C. Modbus/OPC

D. HART® data

Reliable wireless architecture

■

Standard IEEE 802.15.4 radios

■

2.4 GHz ISM band sliced into 15 radio-channels

■

Allows for time-synchronized channel hopping in order to avoid interference from other radios, Wi-Fi®, and EMC sources, thereby increasing reliability

■

Delivers high reliability in challenging radio environments using Direct Sequence Spread Spectrum (DSSS) technology

High accuracy data monitoring

The transmitter can provide fast and reliable corrosion monitoring, identifying within 10 to 20 nanometers of metal loss, based on frequent measurements when using an ER probe.

Rosemount 4390 Series Transmitters

System flexibility

■

The wireless transmitter allows up to a 20 meter cable between probe and transmitter — The transmitter can be installed conveniently for battery replacement and other maintenance without a need for

scaffolding for access

— The transmitter should be installed where it is most beneficial for wireless signal routing, avoiding shadows where radio

communication would be difficult

■

Reads corrosion and erosion probes from most common manufacturers

Data Management

■

Data format (calculated metal loss data, corrosion and erosion rates, or probe raw data) is user selectable from the HART terminal, or from the Emerson Asset Management System (AMS)

■

The corrosion wireless transmitter can be seamlessly integrated with Plantweb Insight Inline Corrosion Application and Fieldwatch™ software suite

■

Calculated metal loss can be transmitted directly to and displayed in Emerson AMS system

■

Calculated metal loss can be transmitted to any historian or control system for data management

Other benefits

The integrated Emerson wireless product, can be combined with other Emerson wireless products in an integrated network, using same gateway for data communication
