Special Features
top
Addtional features comparing model DTMX with basic unit model DTMB
- Memory for up to 100 tension values plus MIN, MAX, PEAK values
- automatic calculation of average and standard deviation
- all these data values can be recalled in the display or downloaded
to a printer or Personal Computer. - 2 Memory modes:
- continuous storage
- on-demand storage - Analog and serial interfaces
- Material selector switch for textile and wire applications (Tex and Wire) assures highest accuracy
- Calibration to customer supplied material is available (up to four different material calibrations)
Features model DTMB
- Microprocessor controlled tension meter for highest accuracy
- Measuring principle: double beam in bending with strain gauge
- Selectable update rates (0.5, 1, 2, or 4 seconds) to provide steady readings when tensions fluctuate (electronic damping)
- Measuring frequency: 62 measurements/second
- Built-in mounting holes permit fixed installation for online use
- The display shows averaged values calculated during the
update interval t1 e. g. every second 1 x
DIP switch
for adjustments
by operator e. g.
display update time
- Saving MIN, MAX and PEAK values during a user-selected period. These values can be recalled at the display.
- Zero adjustment feature permits use of the tension meter in various measuring positions, maintaining highest accuracy
- Calibration to customer supplied material is available (up to two different material calibrations)
- Tension meter with built-in material thickness compensator improves accuracy for changing diameters (from tension range - 500 cN)
- Hand-held unit with built-in mounting holes permit fixed installation for online use
 | Easy mounting: For online application Material thickness compensator: For better accuracy the |
Standard Features
- Everything in operator’s view:
- the guide rollers
- the measured material
- the readings - Filament guide and roller shifting mechanism ensure easy acquisition of the running material
- Ball-bearing mounted, V-grooved guide rollers
- Tension meter with rugged aluminium housing
