This type of Load Cell is composed of a singular part, which makes it easier to use. Inside this Load Cell are two piezo sensors, one measuring Fz and the other measuring Fx.
notion image
In this example of standard assembly, you can see on the front side of the 200N load cell a sticker which is the calibration unit of each axis force, fz and fx, necessary to read correct value based on those reference value.
The 100N suspension assembled on it is used to limit the vibration induced by the sample during testing. There are several variations of suspensions depending on the maximum load it can be effective on.

Mounting the suspension


Choosing the right suspension purchased


A suspension is used to limit the vibration induced by the sample during testing.

There are several variations of suspensions depending on the maximum load it can be effective on.
notion image
 

Example


  • For a test at 30N, you would need to use the 50N suspension.
    By doing so, you will mitigate the vibrations the most.
  • If you work at 48N it would be better to use a 100N suspension as the 50N suspension would not work for vibrations above 2N.

      The labeled force represents the suspension capability, not the nominal operating force.
      The suspension must operate within this specified range.
      Exceeding this limit will lead to ineffective suspension operation.
  1. Fix the suspension then secure it by tightening the side screw using 7/64” Allen key.
    1. ⚠️
      Be careful not to overload the load cell while inserting the suspension.
      You can install the suspension into the holder first before installing the holder on the load cell.
      Or, as shown, you may insert a thin Allen key into the clamping gap during insertion to allow the part to slide in effortlessly.
  1. Install or replace the ball from the ball holder, then hand-tighten the nut or using a wrench (optional).
  1. Secure the ball holder once slide into the suspension by tightening the side screw using 3/32” Allen key.
    1. ⚠️
      The ball holder must not touch the suspension base to ensure proper suspension operation.

    For preliminary testing: The ball may be reused by rotating it to expose a unworn contact surface.
    For final measurements: It is recommended to employ a new ball for each test to ensure accuracy and reproducibility.

    Extension holder

    page icon
    • Use the extension only in particular cases where the ball holder cannot reach the sample.
    • Increasing the ball holder length can negatively affect test results, especially in reciprocating tests. Whenever possible, use the load cell extension block instead.
    ⚠️
    • This extension uses a left-hand (reverse) thread:
      • To tighten: rotate counter-clockwise
      • To loosen: rotate clockwise
