TORQUETRAK REVOLUTIONTORQUE AND POWER MONITORING SYSTEM

Continuous Torque and Power (HPorkW) Data from Rotating Shaft

The TorqueTrak Revolution Series is a torque and power monitoring and control system that features inductive (non-contact) power and data transfer for continuous operation. Designed for applications that require ongoing measurement of torque and/or horsepower, the TorqueTrak Revolution system is custom-machined to install on existing shafting up to 40 inches (1016 mm) in diameter. Machine disassembly is not required. The microprocessor-based system features 14-bit signal processing to provide precise, reliable data in real time during actual machine operation.

Four independent current output signals:

  1. Torque: 12 ± 8 mA, scalable
  2. Power: 12 ± 8 mA, scalable
  3. Shaft Speed/RPM: Pulse Indicator, 5-19 mA
  4. Shaft Direction: Binary Indicator, 5 or 19 mA

FEATURES & BENEFITS

  • Easy Installation
    Rotating Collar and stationary Power Coil are split and bolt together around the shaft. Shaft modification is not required.
  • Convenient Calibration
    Use at factory settings or utilize easy scaling and adjustment tools. No tuning required.
  • Reliable Operation
    Inductive power and data transfer with generous clearance between stationary and rotating parts. No wear surfaces.
  • Digital Data Transmission
    Delivers a clean, noise-free data signal with 14-bit resolution.
  • Robust Construction
    Sturdy hardware and electronics, built for demanding environmental conditions.
  • Onboard Intelligence
    System status indicators confirm proper operation and aid in troubleshooting.
  • Product Support
    Backed by BEI’s proven outstanding customer service, before and after the sale.
