TORQUETRAK 10K
WIRELESS TORQUE SENSOR FOR ROTARY TORQUE MEASUREMENT
Measuring live torque in real-time is easier than ever with the TorqueTrak 10K telemetry system. Convert virtually any drive shaft into a rotating torque sensor by simply mounting the wireless torque transmitter, battery and a torque-sensitive strain gage to the shaft. Use the infrared remote control to adjust transmitter gain, activate the remote shunt calibration or switch the transmitter to standby power mode. The multi-line LCD receiver display and keypad make system adjustments straightforward. Low power consumption in the rugged transmitter allows longer battery life while sophisticated electronics assure accurate and reliable torque data output.

One of the best tools for taking torsional measurements in the field has been the Binsfeld TorqueTrak 10K. It is easy to install and provides a clean signal torque. We have used it to successfully troubleshoot torsional failures of many systems such as VFD motors, reciprocating compressors, couplings, etc. We have also used the TorqueTrak 10K to measure axial thrust in vertical pump systems. In fact, we like the TorqueTrak 10K so much that EDI currently owns six of them!
