S-TYPE LOAD CELL OPERATION MANUAL
2
1.0 INTRODUCTION
S-type load cells manufactured by PCB Load & Torque, Inc.
are accurate strain gage sensors used for weighing and force
measurement. Their high accuracy makes them ideally suited
for critical weighing applications. S-type load cells are
typically used to measure tensile loads, however, compression
loads can also be measured when compression loads are
guided and any resultant extraneous loads are minimized.
Standard 1/4”-28 female threads facilitate ease of installation.
The following document explains the characteristics and
installation of the S-type load cells.
2.0 SAFETY PRECAUTIONS
Failure of the load cell structure may cause personal injury
and equipment damage.
The load cell can withstand loads of at least 150% of the full-
scale capacity before any damage occurs to the sensing
element. Be sure that the load cell and any fixturing used is
properly designed, fabricated, and securely installed prior to
use.
3.0 OVERVIEW
S-type load cells come in a variety of capacities to handle
loads ranging from 50 lbf to 5k lbf.

4.0 MECHANICAL INSTALLATION
Loads applied to S-type load cells must be even and centered.
Compensation linkages (e.g. rod end bearing, alignment
couplers) are recommended to help minimize load
misalignment. When installing fixtures, be sure to thread the
fixture to the load cell, and not the load cell to the fixture. If
alignment fixtures are not used, ensure loading surfaces are
flat and parallel, with loads applied in-line with the sensor.
