The CHECK-LINE® BTM-TTC accurately measures the oscillation frequency of flat, V and ribbed belts of rubber, leather, fabric and composite materials by measuring the natural frequency (Hz). The tool operates by using a very sensitive microphone that analyses the resonance frequency. The small dimensions and the ease in use make BTM-TTC a practical and reliable tool.
- Belt Tension Is measured in Hz units (frequency)
- If tension measurement in Newtons or Lbs units is required, refer to BTM-400PLUS webpage
- It is entirely wireless and self-powered by rechargeable batteries
- It requires no additional tools as it displays the test results directly on its graphic display
- Battery charger supplied as standard
- It emits a beep once the measurement is complete
