The RH 9000 Series Fastener Torque Tension Load Cells are ideal for auditing and analyzing threaded fastener characteristics in production lot testing or in research and development studies!

Often referred to as a Research Head, this load cell is two transducers in one: a strain gage bridge to measure the clamp load generated when the fastener is tightened, and a thread torque bridge to measure the amount of torque seen by the nut.

By breaking out the thread torque data from the torque applied to the fastener, you can calculate the underhead torque, as well as friction coefficients for underhead and thread areas of the bolted joint.

This complete line of the fastener testing load cells provides a signal proportional to the tension developed in a test fastener when the tightening torque is applied. In addition, the torque-tension version measures the thread torque (pitch torque plus thread friction torque) at the same time. The tension or torque-tension output signals from the load cell are read using a conventional strain gage readout device or recorded by a data acquisition device. These load cells also can serve as an integral part of a torque-angle-tension fastener test system when used with a torque-angle sensor and a data acquisition instrument. Recommended is the Model 3200 LabMaster Professional Series from RS Technologies, Ltd.
