Rosemount 2140 (photo) is said to be the world’s first wired HART vibrating-fork level detector. The Rosemount 2140 detects level in applications with high temperatures and harsh conditions that are unsuitable for other level-monitoring devices. It is easy to install and maintain, as there are no moving parts. The device is virtually unaffected by flow, bubbles, turbulence, foam, vibration, sediments content, coating, liquid properties and product variations, according to the manufacturer. It can be used to monitor not only liquids, but also liquid-to-sand interfaces, which enables the detection of buildup of sand or sludge deposits in a tank. For safety-critical applications, a dedicated version of the Rosemount 2140 certified to IEC61508 is available. For installations within safety instrumented systems (SIS), a fully integrated remote proof-testing capability eliminates the need to access the top of the vessel for extracting the device from the process. This saves time and increases process availability, worker safety and efficiency. — Emerson Automation Solutions, St. Louis, Mo.
