ETB-ETX Limited Access Digital Tension Meter

Three long, closely-spaced slender shafts with precision guide rollers or pins at their ends combine with the latest in microprocessor technology to make this instrument top choice for all limited-access, tension measuring applications.

The two outer rollers are tilted upwards for easy material acquisition using the lever on the rear side

The ETPB model is equiped with ceramic pins for line speeds up to 6000 m/min.

Features

With ball-bearing mounted, V-grooved guide rollers for line speed up to 2000 m/min (ETB) or 6000 m/min (ETPB)
Microprocessor controlled for highest accuracy
Battery operated
3 operating modes:
- NORMAL: for standard use
- DAMPING: mode to ensure steady readings, when tension fluctuates (electronic damping)
- PEAK: for retaining the highest reading reached during the measuring period
Guide rollers are mounted on long shafts to reach into tightest places
Specific Test Report with calibration report optionally available
"Zero setting" using a push button for measurement in different measuring positions
Storage of MIN, MAX and PEAK tension which can be recalled or downloaded to a PC
Adjustable electronic damping for better reading when tension is constantly changing
Analog and RS232 output signal to be used for line recorder or PC
Display can be reversed for right and left hand use
Changeble units cN and g
