Load Cells and Load Cell Accessories

We have developed a series of easy to use products to meet your load sensing needs. We offer a range of load cells,indicators and software options to enable you to quickly measure loads,forces and weights. If you are designing a new product you can prototype your products with these standard products and contact us to customize for your specific requirements.

Load Cell Calibration

We calibrate all our iLoad Series capacitive load cells in house using either a deadweight tester (up to 100 lbs) or using a high quality reference load cell that has been calibrated within the last one year and is traceable to NIST standards.

We calibrate each of our capacitive load cells (iLoad Series) using a 9 point calibration at the following load levels (as % of full scale loads):

Capacities up to 500 lb.

0%
25%
50%
75%
100%
75%

Capacities greater than 1000 lb.

0%
12.5%

37.5%

A typical calibration run looks like this:

Capacity: 100 lb.

Load Raw Counts
0 5000000
10 5100000
20 5200000
40 5400000
60 5600000
80 5800000
100 6000000
50 5500000
0 5000000

load cell calibration curve

 


We fit cubic best fit curves and compute the load as follows:

Raw Weight = A*Count^3+B*Count^2+C*Count+D

Computed Weight = Raw Weight – Tared Weight

We provide a calibration certificate with each of our shipped sensors showing applied loads vs. computed loads. You can view a sample calibration certificate here.

We recommend that users recalibrate at least once a year and sooner if the sensor seems to be have been overloaded or damaged during use. Loadstar Sensors provides economical recalibration services for your convenience. Please contact one of our sales representatives for help with calibration services.
