Here are the most common frequently asked questions on the calibration of our force sensors for customers working on research, control, testing and weighing applications. We’ll be providing a series of FAQ posts to cover other aspects of the calibration process.

How long is the calibration valid?

Answer: NIST recommends re-calibration after 1 year. A calibration expiration date is supplied on the calibration data sheet. An in place calibration can extend this period if your internal quality requirements allow, see “re-calibration extended.”

Can the time for recalibration be extended?

Answer: Yes, by performing an in place calibration using a reference load cell, known load or other repeatable methods. You can establish a specific procedure that can be used to evaluate the performance of your sensor. This would be something that should be part or your quality polices which dictate requirements for re-calibration.

What does in place calibration mean on my customer drawing?

Answer: The in place calibration refers to the application of a known load to the transducer after being installed into the final assembly. Variations between the calibration fixtures and final assembly components can result in variations from the factory calibration data, which can be quantified by an in-place calibration.
