3 Tension ranges from 0.1 - 500 cN to 250 - 2500 cN
Electronic tension meter for checking tension of wires at EDM wire machines
Tension meter for EDM wires with approx. 0.05 and 0.25 mm Ø
Special Features
- Microprocessor controlled tension meter for highest accuracy
- Selectable update rates (0.5, 1, 2 or 4 seconds) to provide steady readings when tensions fluctuate (electronic damping)
- Measuring frequency: 62 measurements/second
- 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
- Measuring principle: double beam in bending with strain gauge
- 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 material to be measured or a similar material with the same diameter should be inserted |
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
- Battery operated (AC adapter for continuous operation available)
- Certificate of Compliance with the order 2.1 according EN 10204 is included
- Optionally available: Insprection Certificate 3.1 according EN 10204 with calibration report

Calibration to customized material:
If process material differs significantly from the SCHMIDT calibration material in diameter, rigidity or shape, special calibration using customer supplied samples is recommended. For this purpose a material sample of about 5 m should be supplied.
