SK-500 Belt Tension Meter
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.
