The following chart compares the various forms of torque measurement:
| In-line Sensor | Clamp-on Collar | Strain-Gauged Shaft |
| based on wireless telemetry | based on wireless telemetry | Strain gauges are bonded directly to the shaft |
| No support bearings eliminate maintenance | Immune to oil and dirt effects | The shaft becomes the transducer |
| Requires cutting the shaft or lengthening the machine train to accommodate the inserted in-line transducer | Does not require cutting or lengthening the rotating shaft | Must select a location for the strain gauge, mount it and protect it |
| Pre-calibrated | Can be moved to other similar installations easily in less than 30 minutes | The shaft must be calibrated |
| Ideal application when torque or horsepower monitoring forms part of the final check out of multiple machines | Generally preferred to remote or indirect methods of calculating torque |
