BTM-400PLUS Belt Tension Meter

CHECK-LINE^® BTM-400PLUS

The BTM-400PLUS measures the static tension of flat, V and ribbed belts of rubber, leather, fabric and composite materials accurately by measuring the natural frequency (Hz) of a segment of the belt. Just tap the section you want to measure while facing the sensor to that section then convert 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.

Maximum measurement frequency 800 Hz, however most belts will break near 400Hz

Supplied with both plug-in and cable-connected sensors

*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.
