Rosemount 2140 Level Detector Overview of the Rosemount 2140 Level Detector Emerson’s™ Rosemount 2140 Level Detectors are the newest additions to the expanding range of Rosemount 2100 Series vibrating forks. Utilizing the wired HART protocol, they can be easily integrated into automated systems without the need for additional wiring. Switch easily between HART 5 and HART 7 to further meet requirements. Measurement principle The Rosemount 2140 is a liquid point level device, and is designed to use the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency,...
