Problem
Cause
Remedy
Level to the specified position, the switch is
not activated.
1.
The ball is too heavy to float.
2.
The float ball or displacer is dented,
leaky and filled with media.
3.
Magnetic rod is caused by
ferromagnetic particles or obstacles in the
medium. Movement is blocked
4.
Malfunction of magnetic switch
assembly.
5.
Spring is damage.
6.
Rod connecting float or displacer is
broken.
1.
Confirm the density and contact the
manufacturer to replace the float ball
2.
Replace the float or displacer
3.
Remove the instrument and clean the float
and magnetic rod
4.
Replace switch components.
5.
Replace the spring.
6.
Replace the rod
There is deviation between actual alarm
position and specification.
1.
Process condition is not consistent
with design condition. (The actual density or
alarm setting value is inconsistent with the
design value);
2.
On-site heat tracing caused the
changes in medium density;
1. Determine the process parameters again, and
contact the manufacturer to replace the relevant
parts
2. Adjust the heat tracing temperature to prevent
changes in the density of the medium;
