Rosemount 2130 Enhanced Vibrating Fork Liquid Level Switch

Based on the same vibrating short fork technology as the Emerson Rosemount 2120, the Emerson Rosemount 2130 delivers increased safety with certification to the IEC 61508 safety standard for SIL 2 safety instrumented systems with an SFF greater than 90% (subject to selected output type), and extends our coverage to include the more challenging applications in many industries.

Features include a complete range of process connections, wide choice of housing and wetted parts materials, different switching functions, extended fork lengths and hazardous area approvals, making the Emerson Rosemount 2130 suitable for virtually all liquids.

The Emerson Rosemount 2130 continuously performs advanced instrument health self-checking of the fork and sensor. These diagnostics can detect external damage to the forks, internal damage to the sensor, excessive corrosion and over-temperature.

The Emerson Rosemount 2130 can withstand liquid temperatures from -94 to 500 F (-70 to 260 C) and process pressures to 1450 psig (100 barg).

The Emerson Rosemount 2130 has been TUV tested and approved for overfill protection according to the German DiBt/ WHG regulations. It is certified under safety devices for tanks and piping related to water pollution control.

  • Function is virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids content, coating products, liquid properties, and product variations
  • No need for calibration and requires only a minimum amount of installation
  • Easy terminal access, and safe and easy hook-up with electrical protection features
  • No moving parts or crevices means virtually no maintenance
  • Advanced electronic instrument health and self-checking of the fork and sensor
  • Visible Heartbeat LED shows device status and health
  • Adjustable Switching Delay for turbulent or splashing applications
  •  Local Magnetic Test Point makes functional test easy
  • Short fork for minimized protrusion into pipework
  • Extended lengths up to 157.5-in. (4 m)
  • Fast Drip Fork Design gives quicker response time
  • General area, Explosion-proof/Flameproof and Intrinsically Safe options
  • Increased safety with certification to the IEC 61508 safety standard for SIL 2 safety instrumented systems.
