DTX Digital Tension Meter with Data Logging
Digital hand-held tension meter with colour TFT display, data logging and USB interfaceThe DTX digital tension meter measures the running tension of yarns, fibres, wires and similar materials in textile and wire manufacturing applications. Available in 12 measuring ranges, the DTX combines a three-roller measuring system with advanced recording and analysis functions for monitoring tension during production and quality control.
The colour TFT display offers three viewing modes: numeric measurement, numeric measurement with a bar graph for trend monitoring, and an X-Y diagram showing tension over time. The display can rotate automatically to suit the instrument orientation. Minimum and maximum readings can also be viewed within an adjustable time window of 2 to 60 seconds.
Five memory modes support statistical recording, frozen tension graphs, continuous logging at 2 readings per second, high-speed logging at 1,000 readings per second and individual readings recorded on demand. In modes S, C and F, recording can start automatically when a user-defined tension value is reached. The internal memory stores up to 60,000 measured values across up to 255 measurement series.
For materials that differ from the factory calibration standards, the DTX provides nine customer calibration locations and calibration fine adjustment. A material thickness compensator is available on selected models. The USB interface and supplied Tension Inspect 3 software enable measurement data to be transferred to a PC for analysis and export.

Data Recording Modes
The DTX offers five recording modes for different measurement and analysis requirements.
| Mode | Function |
|---|---|
S – Standard |
Records statistical values over a user-defined measuring period without storing the individual readings. |
H – Hold |
Freezes the graphical display and stores up to the last 128 readings with statistical values for later review. |
C – Continuous |
Records 2 readings per second over a selectable period from 1 second to 1 hour, with statistical evaluation. |
F – Fast |
Records 1,000 readings per second over a selectable period from 1 to 60 seconds, with statistical evaluation. |
D – On Demand |
Stores individual readings when initiated by the operator, together with statistical values. |
Modes S, C and F support a user-defined tension trigger for starting recording. Switching to a different recording mode deletes the data stored in the previous mode.
Guide Roller Options
Roller selection depends on the material being measured and its running speed. The standard DTX uses V-grooved, hard-coated aluminium rollers. The DTX-60K-ASYB is supplied with asymmetrically grooved, tempered-steel rollers.
