For details visit or follow the accreditation link at These strain gage Torquemeters measure and output shaft torque in analog and digital form. Option Z adds speed and shaft power. Their outstanding performance is due, in part, to industries highest Overrange which avoids clipping real-world torque peaks and torsionals. Without high Overrange, clipped peaks cause large errors; see N 20805B. Tight temperature compensation reduces drive heating and gradient effects. lso enhancing performance is elimination of pots subject to misadjustment under vibration and by unauthorized users. The Torquemeters are hardened against VF and other noise sources. Bipolar rotor shunt cal verifies calibration of the entire data chain in W and W modes. Included software displays, plots and stores real-time data on your P. It also isplays and Stores Max/Min and Spread ata. hoose RS232, RS422, RS485 or USB (option) communication. Input power is a single, unregulated voltage. Reverse polarity protection is provided. Password protection is supported. Two Performance Grades are offered; Standard (ode N), and Enhanced (ode ). They are available with 200% (MRT 48800V Series) and 400% (MRT 49800V Series) overload ratings. Option Z adds conditioned speed and power outputs. ll outputs are simultaneously available in both analog and digital form. Should the torque, speed* or rotor temperature exceed the Torquemeters ratings, a warning flag(s) is generated. * Option Z is required to generate a Speed flag. 1

For example: If the set Torque range is 10,000 lbf-in, and the set Speed range is 5krpm then Power Range = 10,000* 5000/83025 = P = 10V analog output. 2. ssumes torque scale is set to the device torque rating. 3. W torque causes the shaft to turn W when viewed from its driven end. W torque causes the opposite rotation. Power polarity tracks torque. 4. Torque signal bandwidth upper limit is 1,000 z determined by integral Bessel response filters. 5. Reverse polarity protected. 6. deg. F. denotes degree Fahrenheit. 7.
