Three Axis Load Cells

The TR3D family of Three Axis Load Cells provide a solution to a variety of force measurement needs. Standard models provide load capacities from 250 lb. to 100,000 lb. in three orthogonal directions. These load cells are used in a vast array of applications including motorcycle axle and suspension force measurements, force measurements at the vehicle tire patch, force sensors for feedback control of test stands, and many more. By using an array of the three axis load cells, it is also possible to measure moment loads. For more load measuring equipment, see our other transducers.

Features

  • Measures forces in three perpendicular directions
  • Environmentally protected
  • Individually calibrated and temperature compensated to ensure maximum accuracy
  • Rugged construction
  • Any model can be provided as a one-directional unit

Overview

Load Cell Design and Manufacture

Each load cell transducer is machined from a solid block of stainless steel or aluminum, which helps ensure that the load cell maintains excellent linearity throughout the entire force range, both positive and negative. Hysteresis is virtually nonexistent.

Crosstalk (the sensitivity of a given channel to loading of other measurement channels or extraneous loading) is minimized by careful arrangement of individual load paths and strain gage elements. As a result, loads applied to other axes and other extraneous loading have no effect on the signal outputs of each axis.

Weatherproof coatings are applied to all strain-gaged surfaces, which guarantees that the load cells survive in any environment experienced in industrial or automotive applications.

What Makes Michigan Scientific Corporation’s TR3D Load Cells Unique?

Michigan Scientific Three Directional Load Cell transducers offer a superior solution over traditional one-directional load cells because they provide more information in a compact package. Often, Three Directional Load Cells are used in applications where an array of one-direction load cells are simply too big and bulky. One such application is replacing engine mounts with Three Directional Load Cells. This allows the measurement of the vector force reacted by the frame without changing how the engine and vehicle attach.

Measuring Forces and Moments

When two or more Three Directional Load Cells are used in a fixturing arrangement, the user can take advantage of the known geometry that is separating the load cells in order to calculate the applied moments as well as forces to which a body is subjected. Thus, it is possible to quantify the loading on all six degrees of freedom of the object under test.

Aircraft Loading Ramp Application

One successful application example of this concept is an aircraft loading ramp that Michigan Scientific instrumented for the military. Designers of the ramp were able to quantify the loads placed on the ramp as vehicles are loaded. To do this, four Three Directional Load Cells were sandwiched between two plates. A series of these plates were then inserted into a loading ramp and vehicles were driven over them. This allowed for a complete description of the loading condition placed on the ramp by the vehicle as it moved.

Michigan Scientific Three Directional Load Cells are configured for easy mounting in a variety of applications using standard hardware. If access is limited, most models are mounted entirely from one side through the use of a bottom thread adapter.

In many applications, the use of a stand-alone force measuring device may not be the most practical solution. In these cases, Michigan Scientific Corporation works closely with the customer to develop a custom measurement device. This is done by either instrumenting production parts, or by replacing production parts with a custom transducer. If you have an application where production Load Cells are not an ideal option, please contact us about a custom solution.
