CTAS-RTRY Series Test Stands

About the CTAS-RTRY Series Test Stands

The CTAS-RTRY Series Test Stands are designed for the testing of powered torque multipliers, i.e. tools that have a continuous rotating output shaft and are therefore usually tested with a rundown fixture. System accuracy is ±0.5% of indicated reading, top 95% of range, which satisfies metrology lab requirements, while the robust features of these stands enables use in the harshest environments.

Intellect Series Transducers

The standard transducers embedded within the test stand are Intellect, (“plug and play”), self-recognizing to the display instrument. The torque ranges available are from the smallest capacity and footprint (8” x 8” 25-500 Lbf/ft imperial or 203mm x 203mm / 33-677Nm metric) up to our largest heavy duty test stand (14” x 19” 750-7,500 Lbf/ft imperial or 355mm x 482mm / 1016-10,168Nm metric).

Rotary Tool Testing

Powered multipliers incorporate a rundown fixture and usually have more distance in height between reaction arm and transducer which requires a bearing collar for minimizing the effects of side loading of the transducer, as illustrated on the left side of the above image. All rundown fixtures are sized appropriately for the capacity of the test stand.
