How to Calibrate a Schmidt Tensiometer
The calibration of a Schmidt tensiometer typically involves a two-point method. When the tensiometer is not under any tension, first adjust the reading to zero. Then, apply a weight that corresponds to approximately 80% of the maximum tension range you expect to measure. For example, if the tensiometer has a range of 10 kg, use an 8 kg weight or slightly heavier, depending on the material's expected tension. Hang this weight from the material being tested, and secure the other end of the material to the tensiometer. At this point, the material experiences tension equal to the weight's value. Adjust the tensiometer reading to match the weight's value. This completes the calibration process, ensuring accurate measurements for future tests.
Some brands of tensiometers offer open calibration features, allowing users to calibrate based on the specific material they are testing. This is especially useful when the material’s diameter differs from the standard calibration diameter. For instance, German brand TENSOMETRIC offers an open calibration system, making it more flexible for different applications. However, other models, like the Schmidt (SCHMIDT) tensiometer, use a closed calibration system, meaning only authorized personnel can perform adjustments. In such cases, it's crucial to select a tensiometer that matches the material’s diameter as closely as possible. If the material is larger than the calibrated size, multiple tensiometers with different diameters may be required to ensure accuracy.
In summary, if your tensiometer supports open calibration, you have more flexibility in adjusting it according to your material’s specifications. If the material’s diameter is consistent, the manufacturer can pre-calibrate it before shipping. For smaller diameters where high precision isn’t critical, calibration based on a median diameter might suffice. Always check the tensiometer’s calibration mode before purchasing, as it can significantly impact measurement reliability and performance.
