2.0 Before installation
2.1 General considerations
The level switch is available as intrinsically safe or explosion-proof/flameproof
versions. There are also ordinary location versions of the level switch for
unclassified, safe areas, and hygienic versions. See “Product Certifications” on
page 15 for hazardous area and hygienic installation requirements.
The weight of the Rosemount 2120 Level Switch (“level switch”) with a heavy
flange and extended fork length may exceed 37 lb. (18 kg). A risk assessment
is required to be done before carrying, lifting, and installing the level switch.
Handle the Rosemount 2120 with great care (Figure 2).

This liquid level switch is designed for open or closed tanks, and pipe
