DTR is a microprocessor based digital indicator, totally autonomous
and with input for strain gauge based torque transducers.
A ≤±0,02% accuracy makes it possible to be used use in quality
systems as first or second line sample, periodically calibrated by a
SIT center. Measuring system consists of a particularly long-term
stable analogue section, of a carrier frequency amplifier which
minimises thermal drifts and of a 16 bits A/D converter which
ensures 65.000 internal divisions.
In order to increase the level of integration among components, a
combined (traditional and SMT) technology has been used, that
makes the indicator more resistant against vibrations and
mechanical stresses, granting the highest reliability of the electrical
This indicator has internal batteries with 1 year autonomy, also
guaranteed by the AUTO POWER OFF function, which activates if
no changes in measurements are detected in the previous 30
The indicator is provided with a programming menu which permits to
choose resolution and digital filter, according to measurements to be
The display also shows an analogue indication bar for pressure, that
is still on, even in programming menu.
Main features :
• 1 YEAR AUTONOMY WITHOUT RECHARGING.
• DIGITAL FILTER.
• PEAK FUNCTION
Positive (torque in clockwise direction)
Negative (torque in anticlockwise direction)
• RS232C OUTPUT (on request).
• DIGITAL CALIBRATION for both positive and negative field, to
remove differences between readings for dynamometers in
tension and in compression loads.
