3-COMPONENT LINK TRIAX SENSORS 

Series 261 3-component force sensors are designed for 
measuring z-axis compression loads from a fraction of a 
pound(N) to 10,000 lbs (to 45 kN), and x and y-axis radial 
forces from a few pounds (N) to 4,000 lbs (to 18 kN).   
These sensors are designed to simultaneously monitor three 
measurements in the x, y, and z-planes.  Similar to the 
piezoelectric link series, this series consists of a triaxial force 
sensor factory installed and preloaded between mounting 
hardware.  Additional customer applied preload during 
installation is not required. 
 
The mounting hardware does not loosen naturally.  

DO NOT 

ADJUST THE MOUNTING HARDWARE

 as loosening or 

tightening of the hardware will change the preload applied to  
the sensor.  Changes to the preload result in changes the 
factory supplied calibration.  In the unlikely event the 
mounting hardware becomes loose, contact PCB’s service and 

repair document for proper instructions for returning the 
sensor to PCB for recalibration.

PENETRATION 

Penetration style sensors are similar to the axial models but are 
specifically  designed  for  compression  and  impact  force 
measurements  in  materials  testing  applications.  Smooth, 
cylindrical  housings  and  curved  impact  caps  avoid  cutting 
through specimens.  This enables measurements to be taken to 
determine yield, deformation, and break point measurements of 
polymers, composites, and other materials. The axial connector 
configuration installs into force thruster apparatus and protects 
the  connector  from  potential  damage.  Versions  offering  full-
scale  measurements  to  5,000  lb  (to  22.24kN)  are  available. 
Tension  measurements  are  possible  with  units  having 
removable caps.

configurations are available, one with a tapped mounting hole 
and impact cap, and the other with tapped holes on both ends of
