Choosing the Right BLRTSX-A Sensor
Consider the following when selecting a BLRTSX-A model:
- What is the maximum torque that will be measured?
- Does the application require both torque and angle measurement?
- Will the sensor be used with a compatible Mountz LTT or PTT Torque Analyzer?
- Is the application using hex-drive or square-drive tooling?
- Will the sensor be used for calibration, power tool verification, joint testing, or fastening analysis?
Selecting a sensor with a measurement range that closely matches the application's normal operating torque provides the best measurement resolution and accuracy while allowing simultaneous torque and angle analysis.
Setup & Adjustment
To use a BLRTSX-A Torque Sensor:
- Connect the BLRTSX-A sensor to a compatible Mountz LTT or PTT Torque Analyzer.
- Verify all cable and mechanical connections before testing.
- Install the appropriate drive adapters or tooling for the application.
- Allow ARC II technology to automatically recognize the connected sensor and load its calibration information.
- Perform torque verification, calibration, or joint testing while the sensor measures both torque and rotational angle.
- Review and record torque and angle data through the connected torque analyzer.
BLRTSX-A sensors include an ISO 17025 Certificate of Calibration and provide a system accuracy of ±0.5% of reading from 20–100% of full scale and ±1% from 10–20% of full scale when connected to a compatible Mountz LTT or PTT Torque Analyzer.
