By analyzing sound waves, belt tension can be analyzed non-contactly.
**Features** - Expanded pre-installed unit mass values for belt types You can display the unit mass value simply by specifying the belt type. - High-sensitivity microphone Improved microphone sensitivity in the low-frequency range. It is particularly effective for long spans of large belts. - Enhanced data selector function The number of data selectors that can store input data has increased. - Adoption of graphic LCD The graphic LCD allows for a significantly larger amount of information to be displayed compared to previous models. - Backlight included Improved usability for work in dark environments. - Other basic specifications - Automatic cancellation of background noise through auto gain adjustment - Auto trigger function - Auto power-off function - Graphic LCD with backlight

basic information
【Main Specifications】 ■ Measurement Range: 10Hz to 5,000Hz ■ Power Supply: 2 AA alkaline batteries ■ RoHS Directive: Compliant ■ Weight: Approximately 120g 【Measurement Specifications】 1. Gain Adjustment (Automatic Cancellation of Background Noise) After powering on, the surrounding noise environment is periodically measured until the "MEASURE" button is pressed, and the microphone sensitivity is automatically adjusted. After pressing the "MEASURE" button, the microphone sensitivity is fixed. 2. Detection of Vibration Waveform Sound waves generated by flicking a stationary belt with fingers are detected by the microphone. 3. Noise Component Removal Noise components are automatically removed by an internal filter. 4. Period Measurement The period of each cycle of the input waveform is measured by the period measurement circuit. 5. Signal Processing Basic waveforms are measured from different vibration waveform patterns established through simulation data processing based on conditions. 6. Frequency Conversion Processing Continuous stable waveforms are converted to frequency. 7. Tension Calculation Processing By inputting the unit weight, width, and span length values of the target belt using the numeric keypad, the belt tension is calculated.
