TORQUETRAK CALCULATORS

Binsfeld’s TorqueTrak Revolution Calculator is used to set-up the TorqueTrak Revolution telemetry system. Use the calculators to determine full scale torque and power measurements. Use the calculator that corresponds to your desired units of measurement. For more information on the equations behind these calculators see Appendix B of the appropriate users guide on the TorqueTrak Revolution page.

Nominal Torque Range

Outer Diameter (D_O) inches

Inner Diameter (D_I) inches (enter 0 for solid shaft)

Number of Active Gages (N) (4 for full bridge)

Gage Factor (GF) (supplied with gages)

Modulus of Elasticity (E) Mpsi (30 Mpsi for steel)

Poisson Ratio (v) (0.3 for steel)

Trans. Sensitivity (S_trans)

Torque Torque

Scale Revolution Power Range

Optional

Full Scale Torque (T_fs) ft-lb

Desired Full Power Scale (P_ref) hp

Set RPM switches in MCU to this value RPM Factor hp (coresponds to 20 mA output) Actual Full Scale Power (P_fs)

NOTE: The Actual Full Scale Power is slightly different than the Desired Full Scale Power value because the RPM Factor is rounded to the nearest whole integer.
