Emerson Process Management announces that its Rosemount 5300 Series Guided Wave Radar (GWR) and 5400 Series non-contacting level transmitters now include the ability to communicate via the Modbus communications protocol.
The addition of Modbus enables the transmitter to emulate the LevelMaster – sometimes known as ROS or tank – protocol. This broadens the application range for these devices even further and enables them to be retrofitted into existing Modbus and LevelMaster networks.
The new transmitters feature an integral HART to Modbus converter (HMC). This enables up to four external HART transmitters of any type to be connected, and their signals communicated via the Modbus network.
The devices can be configured using Emerson’s Radar Master software, point-to-point via HART communications, or remotely by using HART Tunnelling over the Modbus network. Configuring remotely eliminates the need for technicians to climb up vessels, enhancing safety.
