The Timing Chain Tension Sensor offered by Teledyne LeCroy Test Services is a testing tool for automotive engineers who need an accurate and instantaneous measure of torque in the timing chain sprocket. The sensor is actually a torque transducer that senses the net torque imparted to the timing sprocket by both sides of the timing chain.
Prior to the introduction of this sensor, test engineers experienced great difficulty obtaining an accurate signal because of space limitations and the presence of high radial loads. Teledyne Instruments has developed a unique means by which the radial loads are effectively cancelled and the output signal has little or no crosstalk. Output from the sensor typically varies by less than 1% as the sprocket is rotated through 360 degrees. This is important to valve train engineers who need to discern individual valve timing events within the output.
