Transmit Live Torque Data from a Rotating Shaft
Measuring live torque in real time is easier than ever with the TorqueTrak 10K-LP (Low Profile) 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. At only 0.70 inches tall, the TorqueTrak 10K-LP is ideal for applications with very low radial clearance (area around the shaft) such as on vehicle drive shafts.
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 than the TorqueTrak 10K while sophisticated electronics assure accurate and reliable torque data output.
