TORQUETRAK REVOLUTION

TORQUE MEASUREMENT & POWER MONITORING SYSTEM

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.

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.
