China SK-500 Belt Tension Meter: Top Suppliers & Factory for Precise Belt Tension Measurement
Advanced Optical Measurement Technology
The SK-500 utilizes an advanced optical measuring principle. By simply tapping the non-moving belt to induce oscillation, the integrated red LED light source precisely determines the natural frequency of the strand vibration. Unlike acoustic-based meters, the SK-500’s readings are completely unaffected by ambient noise or nearby magnetic fields, ensuring reliable data even in the busiest factory environments.
The unit displays readings clearly on an easy-to-read LCD screen in your choice of frequency (Hz) or actual strand force (Newtons or pound-force). To calculate force values, the meter allows for the input of two critical parameters: free strand length (up to 9.99 meters) and belt mass (up to 9.999 kg/m). This flexibility makes the SK-500 an indispensable tool for a wide variety of drive setups.
Designed for Versatile Field Use
Understanding that access to belts can often be restricted, the SK-500 comes equipped with two distinct probe options. Use the plug-in probe for convenient one-hand operation during routine inspections. For confined spaces where the display unit cannot fit directly over the belt, simply attach the included probe with cable to take measurements in limited access areas with ease.
The user interface is designed for global operation with a multi-language menu, and the rugged, compact ABS plastic housing protects the internal microprocessor from the rigors of daily industrial use. Powered by a standard 9V battery, this lightweight instrument (approx. 170g) is fully portable.

Frequently Asked Questions
How does the SK-500 measure belt tension?
The SK-500 uses an optical measuring principle. By tapping the non-moving belt to induce oscillation, an integrated red LED light source precisely detects the natural vibration frequency of the belt strand.
Is the SK-500 affected by noisy factory environments?
No. Because it utilizes optical sensing instead of acoustic sensors, the readings are completely unaffected by ambient shop noise or nearby magnetic fields.
What data must be entered to calculate the actual tension force?
To calculate and display the tension force, the user must input the free strand length (up to 9.99 meters) and the belt mass (up to 9.999 kg/m).
What probe options are included with the SK-500?
The device comes with two probes: a rigid plug-in probe for convenient one-hand operation, and a flexible probe with a cable for measuring in tight or hard-to-reach spaces.
What units of measurement does the device support?
The SK-500 displays readings on its LCD screen in frequency (Hz), Newtons (N), or pound-force (lbf).
What type of battery powers the SK-500?
The instrument is powered by a standard 9V battery, contributing to its lightweight (approx. 170g) and highly portable design.
