MCRT 49700V Series Digital Torquemeters
Model #49700V
These strain gage torquemeters measure and output shaft torque in analog and digital form. They are available in torque ranges from 25 to 2,000,000 lbf-in with 4X overload rating. A zero velocity speed option adds analog and digital outputs of speed and computed shaft power.
Null, scaling and units of measure are stored in non-volatile memory. There are no noisy pots or switches. Thirty three 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.
