BTM-400PLUS Belt Tension Meter


Made in GermanySupplied with both plug-in and cable-connected sensors

The CHECK-LINE® BTM-400PLUS accurately measures the static tension of flat, V and ribbed belts of rubber, leather, fabric and composite materials by measuring the natural frequency (Hz) of a segment of the belt that has been tapped and then converting it into tension units of newtons (N) or pounds force (lbf).

The instrument uses a pulsed ruby red light source to measure the natural frequency of the vibrating belt. Unlike competitive models, the BTM-400PLUS is NOT affected by ambient noise, providing quick reliable results in all production and field applications.


Features
  • Includes two (2) separate Sensors – a plug-in type for one-handed operation and a cable-connected type for measuring belts with limited access space
  • Compact, easy-to-use design
  • Readings unaffected by nearby magnetic fields or noise
  • Displays tension in newtons (N) or pounds force (lbf) or natural frequency in Hertz (Hz) - selectable
  • Displays Menu in English, German, Spanish, Portuguese, French or Italian & others - selectable

*BTM-400PLUS can measure up to 800 Hz, however most belts will break near 400Hz

**Static tension (T) accuracy depends on the precision of entered values for free belt span (L), density (d) and natural frequency (f) of the vibrating free belt span, that has been plucked or struck, as noted in the relationship: T = 4dL2f2. Note that highest accuracy is achieved in the frequency mode where readings are accurate to <1%, ± 1 Hz.
