Special Features

Tension meter DNW can be used only for pretensioned, non-moving ropes

Calibration is done using a closed force system

Due to the material path the max. error is approx. 3 % FS (full scale)

Special lever reduces the force to extend outer rollers to capture the material to be measured

Tension meter with large, easy to read scale (54 mm Ø)

Linearized scale provides a better reading

Tension meter with shock-resistant movement

Special guides on the bracket assembly and roller shifting mechanism ensure easy acquisition of the material

Standard Features

Everything in operator’s view:
– the guide rollers
– the measured material
– the readings

Ball-bearing mounted, V-grooved guide rollers

Each instrument is individually calibrated for highest accuracy

Special calibration is available

Tension Meter with rugged aluminium housing

Certificate of Compliance with the order 2.1 according EN 10204 is included

Optionally available: Inspection Certificate 3.1 according EN 10204 with calibration report
