The RST- Series is our low range rotating torque sensors that are available in eleven full scale ranges of 10 through 30K inch pounds. The sensing element incorporates bonded foil strain gages of the highest quality along with coined silver slip ring and silver brushes for data transmission. The WR2, Flexural Natural Frequency, and Torsional Stiffness values as stated in the Dynamic Characteristics box below, are approximate and the tabulated data pertains to the torque pickup only, and does not include the effects of couplings or other rotating masses that would be part of a dynamic system.
