Rosemount™ 2140 Level Detector - Vibrating Fork
rosemount 2140 detector vibrating fork
The new Rosemount™ 2140 is the world's first wired HART® vibrating fork level detector for applications including overfill prevention, high and low level alarms, and pump protection.
Providing reliable level detection of all liquids as well as sediments, the Rosemount 2140 offers greater ease-of-use and flexibility with smart diagnostics that continuously monitor electronic and mechanical device health, and a fully integrated remote proof-testing capability, helping to increase safety and efficiency of both plant and workers. The Rosemount 2140:SIS is certified to IEC 61508 (SIL 2) for safety-critical applications.

Features

  • Diagnostics for Predictive Reliability: Continuously monitors electronic and mechanical health to identify issues early and reduce unexpected downtime.
  • Remote Proof‑Testing for Safer Operations: Verify device functionality from the control room, minimizing tank climbs and improving operator safety.
  • High Safety Integrity for Critical Applications: SIL 2 certified with industry‑leading low dangerous undetected failure rates, supporting safety‑critical overfill protection.
  • Reliable Switching in Challenging Media: Fast‑drip short‑fork design drains quickly, resists buildup and provides rapid switching even in viscous, sticky liquids or when media properties are unknown.
  • Flexible and Easy Integration: Fits into wired HART loops with no extra wiring, offering simple commissioning and configuration options.​
  • Consistent Detection Regardless of Orientation: Provides a stable switch point whether installed from above, below or the side.
