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.
FEATURES & BENEFITS
Easy to Use – Fits any size shaft, any torque level. No machine modifications or disassembly required. Calibration is done off-the-shaft. Receiver display and keypad offer user-friendly interface.

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!

For the better part of three decades, Clarage has used in-line torque transducers to measure fan power. Our fans are direct-coupled to motors (i.e. motor shaft-coupling-fan shaft) which are mounted on unitary bases with the rest of the fan. In order to attach the old in-line torque measurement device, we had to slide the motor back, insert the torque meter between it and the fan shaft and use temporary grid couplings to combine them (i.e motor s aft-coupling-torque meter-coupling- fan shaft). After testing was complete, we would remove the torque met and slide the arrangement back to its proper configuration. Being a custom fan manufacturer, we very rarely make the same size fan twice. As a result, most of the temporary grid couplings were scrapped after use. As you can imagine the cost of material and assembly add up over time.
We purchased the Binsfeld TorqueTrak 10K telemetry instrument after extensive research on process improvement. I am happy to say that using the TT10K was simplicity itself and the results were fantastic. We no longer had to re-configure the fan to perform a test. The TT10K receiver and strain gauge could attach directly to the fan shaft and wirelessly transmit the data for us to read power consumption. Binsfeld customer service was impeccable and went a long way in making our initial experience with the device as smooth as possible… I am more than happy to recommend the TT10K product from Binsfeld Engineering.
