WHAT IS LOAD CELL CALIBRATION?
Load cell calibration checks that a load cell and its readout display the true force applied. The cell is placed in a calibrated compression frame and loaded in steps against a certified reference standard, with readings recorded on the way up and on the way down. Any error, non-linearity or hysteresis is documented, and a calibration certificate traceable to NIST is issued. Accurate load cells are essential for pile load tests, tieback proof tests, bridge jacking, structural monitoring and weighing.

LOAD CELL CALIBRATION SPECIFICATIONS
📘 What Is Load Cell Calibration?
A load cell converts force into an electrical signal using strain gauges or a vibrating wire. Over time, overloads, temperature cycles and wear can change its output.
Calibration applies known loads in steps across the cell range and compares the readout to a reference standard, establishing the cell accuracy and calibration factor.
For results to be NIST traceable, the reference standards must have documented calibrations linking back to NIST, with the measurement uncertainty stated.
⭐ Key Features & Benefits of Load Cell Calibration

Load Cell Calibration at WB Equipment
We calibrate compression load cells and their digital readouts from 1 to 1,500 tons in our own test frames, using reference standards traceable to NIST. Each load cell is calibrated with the readout it will be used with, so the numbers on site match the certificate.
Readings are taken at several load steps, loading and unloading, and the certificate shows any error so engineers can rely on the results. Load cells and readouts are also available to rent, already calibrated.
Where Are Calibrated Load Cells Used?
Load cells measure force directly, so they are used wherever an accurate load reading is needed, for example:
● Pile load tests: measuring the true load applied to a test pile.
● Tieback and anchor testing: confirming proof and performance loads.
● Bridge and structure weighing: finding the weight and center of gravity before a lift.
● Jack calibration: acting as the reference when jacks and gauges are checked.
● Long-term monitoring: tracking loads in props, struts and anchors over time.
Many specifications require a load cell calibration within the last 12 months, and we can turn it around quickly.
Your Questions Answered - Load Cell Calibrations
What is load cell calibration?
It is the process of applying known loads to a load cell and comparing its readings to a reference standard, so its accuracy is known and documented.
Why do load cells need calibration?
Overloads, temperature, moisture, cable damage and age can change a load cell output. Calibration confirms it still reads correctly.
How often should load cells be calibrated?
Usually every 12 months, before critical tests and after any overload or damage, or as required by your specification.
What does NIST traceable mean?
The calibration links through documented reference standards back to the National Institute of Standards and Technology.
Do you calibrate the readout too?
Yes. We calibrate the load cell and its digital readout together so the whole system reads correctly.
What types of load cells can you calibrate?
Resistance (strain gauge) and vibrating wire load cells, both solid and center-hole designs.
What capacities do you calibrate?
From about 1 ton up to 1,500 tons.
What is a center-hole load cell?
An annular load cell with a hole through the middle, used on tiebacks, rock bolts and anchors with the bar passing through it.
Why are bearing plates important?
Load cells are sensitive to eccentric loading. Correct bearing plates keep the load axial both in calibration and on site.
Can you repair a damaged load cell?
Contact us. Cables and connectors can often be repaired. Damaged strain gauges may require replacement.
Do you rent load cells?
Yes. We rent load cells with digital readouts, supplied with current calibration certificates.
How do I send load cells for calibration?
Call 866-522-5464 to book, then ship the cells, cables and readouts securely packed.
