| Shaft Stiffness: lbf-in/rad N-m/rad |
These strain gage based Horsepower/kW-h Meters measure and output shaft power, energy (option), torque and speed in analog and digital form. Digital computation of power and energy is errorless. They are available in ranges from 25 lbf-in to 2,000,000 lbf-in (power ranges from 5.95 to 38,100 hp) with a 4X overload capacity. Both shaft and flange style models are offered.
Null, scaling and units of measure are stored in non-volatile memory. There are no noisy pots or switches. Fifty-one common units of measure are supported without requiring recalibration. Eleven user selectable Bessel filters avoid delay distortion and overshoot errors. These models incorporate new technology that hardens them to EMI generated by IGBT based adjustable speed drives.
Included software interfaces Windows-based PC’s and displays and plots real time data. Use it to select 5V or 10V analog outputs, filters, scaling, units of measure and/or to control measurements.
