DTVB - DTVX
Digital tension meter with measuring head rotated by 90° |
Tension meter with small rotated measuring head, where access space is limited or where filaments run close together.
The model DTVB is recommended where the standard model DTMB cannot be used. The model DTVX is a special purpose model for when the standard model DTMX cannot be used.
Note: This model does not include a material thickness compensator
|
 Turned-up outer finger edges guide the running filament into the roller grooves | | Small, ball-bearing mounted, V-grooved guide rollers
| | Filament guide and roller shifting mechanism ensure easy acquisition of the running material | | Rugged aluminium housing | | Specific Test Report with calibration report optionally available
|
| | Length of measuring head approx. 59 mm | Everything in operator's view:
- the guide rollers
- the measured material
- the readings | | Ball-bearing mounted, V-grooved guide rollers | | Battery operated (AC adapter for continuous operation available) |
