DYNAMOMETERS – PIAB
PIAB DYNAMOMETERS (MADE IN SWEDEN)
The PIAB Dynamometer is excellent for measurement and control of
tension forces, where accuracy, reliability and safety in all conditions
is required.
G DYNAMOMETERS & LOAD CELLS
The PIAB Dynamometer is extremely robust and reliable instrument and is an
all-weather instrument.
TECHNICAL DATA
ACCURACY: ±0.6% of the max. capacity
WORKING TEMPERATURE: Max.+60°C
TAREING: The dynamometer can be tarred to approx.10% of the full scale.
To obtain best accuracy the dynamometer should be supplied calibrated for
a known tare.
SCALE: White lacquered with black graduation.
PROTECTION CLASS: IP 67, IEC 529 NEMA 4X
