Tension2Go App to Measure Pretension Using a Smartphone

This app is temporarily unavailable.

With the Tension2Go app, users can employ their smartphones to quickly verify the correct pretensioning of industrial belts from the ContiTech Power Transmission Group - whether it be a case of initial installation, a maintanance job or fault diagnostics.

In order for the belt to run properly, it is crucial that the belt tension be correct and this is a practical tool for use on-site.

The application Tension2Go can be downloaded in the App Store or at Google Play free of charge.

How Does It Work?

The app measures the natural frequency of the belt.

  1. The opening of the smartphone microphone should be held 1-5 cm above the span length. It must be directed toward the belt.
  2. The belt should be set into vibration so that the airborne noise can be recorded.
  3. Using the frequency value that is determined, the user can then select the pretensioning force. As an alternative, Tension2Go can also calculate the tension of the belt directly if the belt type and the length of the free belt section has been entered before the measurement is taken.

While the measurement is being taken, there must not be any contact between belt and smarphone.

The belt must be standing still for the measurement.

For the most precise value, ensure a quiet environment since noises can influence the result. In such cases, simply repeat the measuring process for better results.

Parameters

  • The measurement picks up frequences in the 20-to-1000-Hz range.
  • The measurable free span length fluctuates within a range of 200 mm to 800 mm.
