Features list
The Rosemount 2130, version with 2130***E in the model number, is designed for operating in high
process temperatures of –94 to 500 °F (–70 to 260 °C).
The Rosemount 2130, version with 2130***M in the model number, is designed for operating in
mid-range process temperatures of –40 to 356 °F (–40 to 180 °C).
Based on vibrating short fork technology, the level switch is suitable for many liquid applications.
It is virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids content, coating
products, liquid properties, and product variations.
Dry
(1)
1.
The switching point does vary with different liquid densities (see
).

Normal mode
The operating mode in which the Rosemount 2130 considers a 0 Hz fork frequency to
represent a wet condition (and not a fault).
Enhanced mode
The operating mode in which the Rosemount 2130 considers a 0 Hz fork frequency to
represent a fault condition.
