China SK-500 Belt Tension Meter - Precision Belt Tension Measurement by Trusted Suppliers and Factory
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.
