 Special
Features
o Microprocessor controlled for highest accuracy
o Measuring frequency: 62 measurements/second
o Selectable update rates (0.5, 1, 2 or 4 seconds) to provide
steady readings when tensions fluctuate (electronic damping)
o The display shows averagedvalues calculated duringthe update
interval t1
o Recall of measuredMIN, MAX and PEAK values
o Field adjustment function for fine tuning of the calibration
o Zero adjustment feature permits use of the tension meter in
various measuring positions, maintaining highest accuracy
o Built-in material thickness compensator improves accuracy
for changing diameters
o Built-in mounting holes permit fixedinstallation for online
use
o Calibration to customer suppliedmaterial is available (up
to twodifferent material calibrations)
|
Standard
Features
o Everything in operator's view: - the guide rollers - the measured
material - the readings
o Filament guide and roller shifting mechanism ensure easy acquisition
of the running material
o Ball-bearing mounted, V-grooved guide rollers
o Rugged aluminium housing
o Battery operated (AC adapter for continuous operation available)
o Specific Test Report with calibration report optionally available |
