Rosemount 3408 level transmitter

Emerson has introduced the Rosemount 3408 level transmitter, a non-contacting radar device designed to optimise ease of use.

While the benefits of radar level measurement are widely acknowledged, leading to the technology’s fast-growing adoption across multiple industries, radars are still sometimes perceived as being complex to commission, operate and maintain. Addressing this concern, the device provides a range of functions that reduce complexity throughout its lifecycle, including an intuitive interface, Bluetooth wireless technology remote capabilities, predictive alerts, in-situ verification, data historian and an upgradeable design.

The user interface provides pictorial instructions, allowing operators to be guided through installation, commissioning, proof-testing, operation and maintenance.

The device is based on frequency modulated continuous wave (FMCW) technology and is also suitable for use in critical safety applications such as overfill prevention, as it is SIL 2-certified and designed according to the IEC 61508 standard.

Emerson’s proprietary Smart Meter Verification software provides an easy means of verifying the health of the device, without interrupting the process. Official records of device verification are generated, and an advanced diagnostics suite continuously monitors key device health and process parameters. A built-in historian enables users to access stored process data and alerts to gain process insights and aid troubleshooting.

The transmitter can be proof-tested remotely and in situ, which makes the procedure quick and easy, saving time and increasing plant and worker safety. In the event of device failure, its exchangeable design enables the simple replacement of a cassette within the transmitter housing, rather than replacing the entire transmitter head.
