What is a Force Probe?

A force probe (also known as a load cell or strain gauge-based force sensor) is a device that converts a mechanical pressure, tension, compression, or weight into an electrical signal. They are commonly used for automotive applications, industrial automation, and aerospace.

They can be used to determine the stiffness of a sample, to characterize biomembrane interfaces and other mechanical properties of cells, organelles and macromolecules. They can also be used to understand the mechanisms of biological reaction kinetics based on the restoring force of a stretching or compressing molecular system.

The program enables the user to set tracking intervals and parameters, visualize the results in several different ways, precisely measure the probe geometry and perform basic analysis of deformation and force time courses. In the event that the SD2 contrast metric and/or tracking metrics decrease below certain threshold values, the program issues warnings and logs the frame of incident. In the event that the axial deviations and/or geometrical parameters do not return to their pre-experiment values, the program automatically invokes generic probe geometry to provide deformation and uncalibrated force time courses.

To prevent output drift, overload and damage from environmental conditions, FUTEK recommends a yearly recalibration of your force measurement sensor. This can be done in our onsite laboratory or on your own site with one of our turnkey calibration packages. Please contact our Technical Support team for more information on how to best calibrate your force sensor. They can assist with determining the most cost-effective recalibration service interval for your specific application.
