https://www.ato.com/torque-sensorWe're currently looking at the ATO-TQS-D03 digital rotary torque sensor with a 100 Nm capacity. This seems to be appropriate for our needs, but I have some questions please provide some clarification.
To get readings for the torque and rpm of the shaft in real time, I understand that the USB to RS485 Cable + Software is needed. Do we also need to select RS485 for the output? I just want to make sure that we can transfer the sensor's output data to a laptop and generate some graphs from it. What would be the benefit of selecting RS485 & +/-5V or RS485 & 0-10V?
ATO-TQS-D03 is a not bad choice. For the torque sensor output signal, RS485 & ±5V, or RS485 & 0-10V, note that if you order the ±5V option, you'll get the output torque in positive and negative directions. If you order 0-10V, you won't be able to distinguish positive and negative torque directions.
Regarding your setup, you can't measure separately. In other words, you can't fix one end of the shaft. Instead, you can add a brake or a generator to it.
