TORQUE & POWER MONITORING SYSTEM
The TorqueTrak Torque and Power Monitoring System (TPM2 series) is a rugged precision instrument designed to measure torque and/or power on rotating shafts in real time using precise strain-gage sensors. The TPM2 is custom designed to fit on shafting as low as .75″ (19mm) and up to 48″ (1220 mm) in diameter. Machine disassembly is not required.

FEATURES & BENEFITS
Easy Installation – Rotating Collar and Stationary Ring are split and bolt together around the shaft. No Machine assembly or Shaft modification is required.
Robust Construction – Sturdy hardware and electronics, built for demanding environments.
Reliable Operation – Inductive power and data transfer with generous clearance between stationary and rotating parts. No wear surfaces.
System Status Indicators – Confirm proper operation at a glance. Expedites troubleshooting.
Easy-on Collar – Rotating Collar is designed to accommodate small variations in shaft diameter and clamps to the shaft using standard tools.
Communications Made Easy – High-speed bi-directional communications link interfaces with PC or PLC. User-selectable sample rate up to 4800 samples/second.
Product Support – Backed by BEI’s proven outstanding customer service, before and after the sale.
