4 Tension ranges available from 10 - 100 daN up to 40 - 400 daN

Rugged mechanical tension meter for measuring pretensioned ropes up to Ø 4 mm

Hand-held unit for tension ranges up to max. 400 daN

Tension meter with large, easy to read scale


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 running 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

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.
