The FM style load cell provides easy and conven-
ient mounting to the roll that is being measured
(used with pillow blocks). The load cell is a strain
gauge style unit that is ideal for heavy tension
applications. It can be mounted regardless of ori-
entation, but has to work in compression. Only
the perpendicular force (resultant) is measured by
the load cell. The perpendicular force can be at a
maximum permitted angle of +/- 30 degrees.
Correct load cell sizing must be adhered to so
potential overload forces do not damage cells.

0VDC (No load)
5VDC (Rated load)
Two potentiometers and LED’s are located near
the “D” connector (See Figure 1) for visual indi-
cation. When used in the nominal range, both
LED’s are “ON”. Although the load cell has been
factory calibrated. The unit may be rescaled if
necessary. It is recommended that a qualified
technician do this procedure.
Attach a digital volt meter between the signal
lead (yellow) and 0VDC (ground). With no load
on the cell adjust the zero potentiometer for a
0VDC output. The zero setting LED should be
“OFF”. Any voltage above 0VDC, the zero LED
will turn “ON”.
Apply the mazimum load to the cell. Adjust the
gain potentiometer for a 5VDC output reading.
The gain LED should be “OFF” at a 5VDC output
level. Remove the load and insure the gain LED
is “ON”.
The zero and gain adjustments may need to be
repeated a couple of times to insure proper set-
ting.
