Pneumatic Torque Gun Control
Pneumatics can be used to provide remote torque gun control that is both accurate, simple and very repeatable.
In this sketch, a QB2 is piloting a PSR-Series air volume booster that is controlling pressure to a torque gun. A torque sensor is providing direct feedback to the QB2. This feedback is in a 0-10 VDC analog signal that represents the full torque range of the sensor.
The QB2 is calibrated at 0-10 VDC = 0-100 PSI – in this case, 100 PSI would create the maximum torque on the torque gun. This customer’s process has 6 specific torques they use, so a selector switch was used that provides 6 specific output VDCs. These VDCs are the command signal to the QB2. A 50% command to the QB2 would equate to a 50% (of torque gun capacity) torque in the process.
