Bearingless Digital Torquemeters-85800V

Model #: MCRT® 85800V
Description:

Flanged Wireless In-line Rotating Torque Transducer

Features

  • Best Real World Accuracy of Any Similar Torquemeter, Torque Sensor or Torque Transducer
  • Wide Installed Measurement Bandwidth
  • Simple Installation, Tolerant of Rotor-Stator Misalignment
  • Low Sensitivity to Clamping Loads
  • Noise Tolerant Carrier Amplification
  • Bi-Directional Rotor Shunt Calibration
  • No Hoop or Caliper Antennae
  • ISO 17025 Accredited, NIST Traceable Bidirectional Calibration

MCRT® 85800V Torquemeters have very high accuracy in real-world applications, not just in the cal lab.That’s due to very high stiffness which yields wider installed bandwidth and faster response than competitive devices. Furthermore, Industries highest Overrange avoids errors which occur when torque peaks are clipped. Three performance grades are offered. A Carrier Amplifier, immune to dc and low frequency signals, handles the torque bridge output. Hardening against electromagnetic interference (EMI) generated by Variable Frequency Drives, ISM transmitters and other industrial noise sources further enhances performance. Bi-directional rotor shunt cal verifies calibration and operation of the entire data chain in CW and CCW modes.

It is invoked via I/O line or from your computer. Multiple bridges and elegant design provide exceptional immunity to extraneous loads. These devices have very high stiffness, low deflection and provide unsurpassed static and dynamic system response. The installed Torquemeter results in a torsionally stiff driveline, with low overhung moment and a short overall length.

The torque signal is digitized on the rotor and sent to the stator where analog, and Com Port outputs are created. Choose RS422/RS485 or USB (option) communication. Included software interfaces with your Windows-based PC. It displays Real-time, Max/Min and Spread Torque, Speed and Power, Rotor Temperature, does limit checks, real time plots and stores test results. Password protection may be invoked.
