How to handle the level switch
Handle the level switch with great care
The weight of a 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.
Use both hands to carry the high-temperature versions (2130***E) and extended length versions
(2130***M) of the level switch. Do not hold using the forks.
For hygienic applications, the level switch must be hygienically cleaned before installation and handled in
strict accordance with hygienic standards.

Installation recommendations

Test the system by using the magnetic test point (see

Avoid installing near the liquid entering the tank at the fill point.

Avoid heavy splashing on the forks. Increasing the time delay reduces accidental switching.

Ensure that the forks do not come into contact with the tank wall, any internal fittings, or obstructions.

Allow for a sufficient distance between product build-up and fork (see

Ensure the installation does not create tank crevices around the forks where liquid may collect.

This can happen with high-viscosity and high-density liquids.
Extra consideration is needed if the plant vibration is close to the 1400 Hz operating frequency

of the level switch.
Supporting the extended fork avoids long fork length vibration
