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

Other tension ranges and measuring head widths are available on request.
Other units of measure are available, such as  g.
* Depending on model, either width of filament guide or outer distance between outside guide rollers.
** Suitable for 95 % of applications - PA = Polyamide Monofilament
*** Material Thickness Compensator

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.
