Sonic Tension Meter Calibration

Sonic Tension Meter measures belt tension by evaluating the harmonic characteristics of a vibrating rope or belt. Ropes and belts, vibrate at a specific natural frequency based on their mass, tension, and length.


The Sonic Tension Meter can easily be operated by a user for quick and accurate readings on all types of synchronous belt drive systems and ropes etc.  These devices are particularly useful to reach inside cramped locations where it is not easy to take measurements.  An optional flexible sensor can be bent for convenience, and one-hand operation. You can also use it in high-noise or windy environments by using an optional inductive sensor.


Procedure to find tension:
  1. Enter the data such as the mass constant, width & span length.
  2. Hold meter to belt or wire span, then strum to vibrate it.
  3. The meter will measure the vibration and convert it into tension value.


Physical characteristics of such units are:


Calibration and adjustment


A measurement error is a difference between a measured value of quantity and its true value. Such errors tend to become more frequent after the device has been used for a long time.  After some time, the deviations might be so high that they are no longer within the specifications, which means that quality is no longer assured.


By calibrating the device, the measurement error can be determined and documented. If the measurements are outside the expected range, the device needs to be adjusted. In this process, the measuring instrument is recalibrated so that measurement errors are lowered and deviations from the setpoint value are within the manufacturer’s specifications.


Why calibration is necessary?



The main purpose of calibration is to ensure the reliability of the instrument so that it can be trusted. It also determines the accuracy of the instrument and ensures the readings are consistent with other measurements.


Calibration improves assurance of precise measurements required in research, development, and innovation, as well as the manufacturing of products and services.  It could also void your warranty if your instrument is not calibrated.


There are significant costs that may arise from legal action for damages that might be filed against you for damages due to poorly calibrated instrument, as compared to the expenses of calibration.  If you wish to establish long-term business relationships, ensure that your products and services are of good quality, therefore, you need to calibrate your equipment regularly.


Accurate measuring is probably the most effective way of averting costly repairs. This applies in particular to maintaining international standards for quality management systems such as ISO 9000.
