What kind of meter is the laser tension meter?


Laser tension meter is another name for infrared tension  meter. In fact, there is no laser tension meter, but infrared tension  meters. Infrared tension meter is an instrument used to detect the tension of belts such as timing belts and transmission belts. Rely on infrared to measure the vibration frequency of the belt, and calculate the tension of the belt through a formula.

The following is the NBT-800 infrared tension meter produced by Betten Technology Co., Ltd.


The Infrared Belt Tension Meter can measure the belt tension of motor and other machines quickly.

Using laser sensor, direct measurement, more convenient than mechanical sensor.

The size of the split sensor is small, which is suitable for measuring in a narrow space.

Metric or imperial units can be used to display readings.

With automatic power off function.


This tensiometer can measure the natural vibration frequency of the belt through the emission and reception of the laser, and then calculate the tension value of the belt by combining the input belt mass and the free belt length.
