Level switch has huge temperature range

New vibrating-fork liquid level switch provides point readings in extreme applications.


Emerson Process Management has launched a new version of its Rosemount 2130 vibrating-fork liquid level switch, designed especially for use in extreme high and low process temperatures. The new design can operate from -94 to 500 °F (-70 to 260 °C), so it can be used in many challenging applications.

The Rosemount 2130 level switch has become a popular choice for high and low level alarm and pump control duties. Emerson attributes this to its simple but reliable design with no need for on-site calibration. Addition of the extreme temperature version allows site managers the possibility to standardize on the Rosemount 2130 across a wide range of process environments.

Each unit has a heart-beat LED that gives an instant visual indication that the unit is operational. Moreover, the built-in fault monitoring and self diagnostic functions can detect any corrosion of the forks or any other internal or external damage or breaks in the internal electrical wiring, which triggers a warning LED and fail-safe handling of the load.

Additional options include a low-density version suitable for liquids with a specific gravity down to 0.5 (500 kg/m3), plus a wide choice of electronic output options for use as part of an analog or digital plant monitoring network. The new model is available with 316L stainless steel as standard or corrosion resistant alloy C wetted parts, as well as a choice of aluminum or stainless steel housing options.
