DTMX
For applications requiring additional process data |
Electronic tension meters manufactured by Schmidt. Providing detailed process data and analysis. Available in two models: DTMB and DTMX
|
 2 Memory modes:
- Continuous storage
- On-demand storage | | Analog and serial interfaces | | Calibration to customer supplied material is available (up to four different material calibrations) | | Measuring frequency:
62 measurements/second | 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. |
| | Material selector switch for textile and wire applications (Tex and Wire) assures highest accuracy | | Selectable update rates
(0.5, 1, 2, or 4 seconds) to
provide steady readings
when tensions fluctuate
(electronic damping) | | Built-in mounting holes
permit fixed installation
for online use | | can be connected to a PC or printer |
