TORQUETRAK TPM2

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.

    • 91mm/3.6″ minimum shaft space
    • 19mm/.75″ minimum shaft diameter

 

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.
