Measuring live torque in real time is easier than ever with the new 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 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.
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.
Infrared Remote Control - Control transmitter operation including channel select, gain/range, shunt calibration and low-power standby mode.
Reliable Data Transmission - Clean, noise-free data signal through analog voltage output or digital data output via RS-232.
Standby Power Mode - Extends transmitter battery life without disconnecting battery.
16 Channels - 500 Hz Frequency Response Use; multiple systems simultaneously.
User Adjustable Gain - Amplify the strain/torque signal to the most useful level.
