Rosemount 2140 wired HART vibrating fork level detector

Tuesday, 14 February, 2017 | Supplied by: Emerson Automation Solutions


Emerson Automation Solutions has launched the Rosemount 2140 wired HART vibrating fork level detector.

The Rosemount 2140 is designed to perform in applications with high temperatures and harsh conditions unsuitable for other level monitoring devices. The device is virtually unaffected by flow, bubbles, turbulence, foam, vibration, sediments content, coating, liquid properties and product variations. It can be used to monitor not only liquids but also liquid-to-sand interface, which enables the build-up of sand or sludge deposits in a tank to be detected.

Compatible with the HART 5 and HART 7 hosts, the Rosemount 2140 enables operators to continuously monitor electronic and mechanical health. Frequency profiling functionality immediately detects any build-up, fork blockage or excessive corrosion, indicating maintenance may be required and allowing this to be scheduled during periods of downtime. In addition, power advisory functionality monitors voltage and current drawn over the device’s lifetime with a process alert for potential issues that could become a problem, such as corrosion.

An optional integral LCD display shows switch output states and diagnostics so an operator can inspect the device locally. Also, selectable Media Density and Media Learn functions help configure appropriate density settings to calculate and maintain optimum and consistent switching points in fluids of unknown properties.

For safety-critical applications, a dedicated version of the Rosemount 2140 certified to IEC61508 is available with a 97% safe failure fraction and 96% diagnostics coverage.
