How to Select the Right Load Cell

Selecting a sensor can be difficult since each offers its own advantages. The right supplier can help you select the best equipment for your application. You should choose a supplier with the knowledge and experience to assist before, during and after the purchase. After you’ve identified the right load cell, in order to obtain accurate measurement, you still need to install it correctly and you will need instrumentation to go with it. Here are some guidelines to help you identify the right load cell for your application.

 

Understand your Application

Decide how you want to conduct the measurement and how you will apply the load (will you be measuring tension, compression, tension and compression, multi-axis, bending, etc.) Some examples of load cell applications include tank weighing, bite force measurement, break point tests, durability studies and many more.

 

Define your Capacity Requirements

Before selecting the capacity, you must consider all extraneous load and moments. You’ll want to select a capacity over the maximum operating load. You should also determine what engineering units you require.

 

Define your Needs

Do you have static or dynamic load? Will this load cell be used in-line or side mounted? Is it Female/Male thread, In-line, Side Mount, Flange Mount, Thru-hole, or Compression Washer?

 

Define your Size & Specification Requirements

  • width, height, length, weight, etc.
  • special cabling lengths or other requirements
  • overall accuracy, output, nonlinearity, hysteresis, creep, bridge resistance, resolution, frequency response, etc.
  • submersible, cryogenic, high temperature, etc.
  • special calibration requirements, certifications, labeling considerations, frequency response, etc.

 

Select Instrumentation (if necessary)

If you need an instrument for your application, select it at the same time you select the load cell. This will help ensure compatibility of the entire system. Don’t forget to purchase system calibration with your order. This integrates your sensor and instrument as one system.
