Hans-Schmidt DTMB-500 Digital Tension Meter and 27 similar items

The Schmidt DTMB Digital Tension Meter accurately measures the running line tensions of yarns, fibers, wires, cables, optic fibers and similar process materials. The DTMB provides critical process information required to meet today's strict quality reporting systems mandated under ISO 9000 guidelines. Applications: Yarns Fibers Wire Cables Optic Fibers Tire Cord Webs Warps Tapes Bands Tows Ribbons and more Features Precision Strain Gauge Sensing for Highest Accuracy A precision strain-gauge sensing system accurately measures the force on the middle sensing roller. This is converted into a highly accurate tension measurement using proprietary calibration formulas which correct for material diameters, rigidities, gravity and other critical parameters. Thickness Compensator Automatically Adjusts Calibration The microprocessor automatically fine-tunes the calibration to correct for different material diameters permitting a single DTMB or DTMX to be used on a wide range of process materials without sacrificing precision or accuracy. Field Adjustment for Fine Tuning of the Calibration Increase or decrease the displayed readings in 1.5% increments or select Special Calibration (SP). High-Speed Measurement Captures Max, Min Peak Tension Values Tensions are sampled 62 times per second and averaged over a user selected interval of 0.5, 1, 2 or 4 seconds. The maximum, minimum and peak values are stored for recall to the display. Precision V-Grooved Rollers for Line Speeds Up to 5,000 m/min Ball-bearing mounted, V-grooved rollers are hard coated aluminum for speeds up to 2,000 m/min. Optional High-Speed Rollers (U) are offered for 5,000 m/min. Hardened steel, ceramic and plastic rollers are also available. NIST-Traceable Calibration Certification optionally available Rugged Aluminum Housing For Long-Term Durability Die-cast aluminum housing and surface-mount electronics insure trouble free operation in the toughest environments. DIP switch for adjustment by operator e. g. display update rate ? Saving MIN, MAX and PEAK values during a user-selected period. These values can be recalled at the display. Material thickness compensator: For better accuracy the material to be measured or a similar material with the same diameter should be inserted Thickness Compensator Automatically Adjusts Calibration The microprocessor automatically fine-tunes the calibration to correct for different material diameters permitting a single DTMB or DTMX to be used on a wide range of process materials without sacrificing precision or accuracy.
