DTMB
Basic unit for many applications |
Electronic tension meter manufactured by Schmidt for applications with yarns, fibers, wires, cables, optic fibers, tire cord, webs & warps, tapes & bands, tows, ribbons etc.
Easy mounting
For online application, built-in material thickness
compensator with material sample inserted
Field adjustment function
for fine tuning of the calibration for materials which differ from factory standard calibration material; the
displayed value can be increased or decreased in ±1.5% increments.
The DTMB provides critical process information required to meet today's strict quality reporting systems mandated under ISO 9000 guidelines. |
 Precision strain gauge sensing for highest accuracy measures force on middle sensing roller | | Selectable update rates (0.5, 1, 2 or 4 seconds) to provide steady readings when tensions fluctuate (electronic damping) | | Recall of measured
MIN, MAX and PEAK values | | Zero adjustment feature permits use of the tension meter in various measuring positions, maintaining highest accuracy | | Built-in mounting holes permit fixed
installation for online use | Everything in operator's view:
the guide rollers
the measured material
the readings | | Measuring frequency: 62 measurements/second | | The display shows averaged
values calculated during
the update interval t1 |
| | Calibration to customer supplied
material is available (up to two
different material calibrations) | | Filament guide and roller shifting mechanism ensure easy acquisition of the running material | | Ball-bearing mounted, V-grooved guide rollers for Line Speeds up to 2,000 m/min | | Rugged aluminium housing for long-term durability | | Battery operated (AC adapter for continuous operation available) | | Specific Test Report with Calibration report optionally available
| | Material thickness compensator for better accuracy | | Microprocessor automatically fine-tunes the calibration to correct for different material diameters. |
