The Checkline BTM-400Plus Digital Belt Tension Meter, Belt Frequency Meter, Sonic Tension Tester, Range 3 - 800 Hz is supplied with both plug-in and cable-connected sensors. The BTM-4000PLUS Belt Tension Meter, also called a Sonic Tension Meter, 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 BTM-4000PLUS 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.
3 - 800 Hz (BTM-400PLUS can measure up to 800 Hz, however most belts will break near 400Hz)
Accuracy
± 5% or better (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
Sensing Distance
0.200" - 1.6" (5 - 40 mm), typically (2.5"/60 mm max, depending upon ambient light & surface of belt to be measured)
Casing
ABS Plastic
Display
2 line LCD, 16 character per line
Input Range
free span length
Power Supply
9V battery
Kit Contents
The BTM-400PLUS is supplied as a complete kit, including two (2) separate Sensors – a plug-in type for one-handed operation and a cable-connected type for measuring belts with limited access space
