5. Speed Measuring Systems

Optical Speed Measurement: 60 pulses per revolution (PPR), maximum speed 20,000 rpm, minimum stable pulse speed above 1 rpm.
Inductive and Magneto Resistive Systems: Not applicable or unavailable for this product.

6. Mechanical Dimensions and Mounting

Rotor weight approximately 0.1 kg; stator weight unspecified without options.
Mechanical tolerances such as flatness and concentricity are defined by manufacturing and detailed in product drawings.
Axial and radial displacement nominal and tolerance values are referenced in technical drawings.

7. Additional Information and Recommendations

Optional torque ranges and dual-range torque meters available upon request with dedicated data sheets.
Load limits apply only when loads are not combined; combined loads up to 100% cause a maximum nominal torque error of 0.3%.
Supply voltage must remain within specified range; long cable lengths may reduce voltage at the sensor.
Configuration interface is USB (UART).
Material used is steel; measuring range extends to 110% of rated torque.
Balance quality complies with DIN ISO 1949 - G6.3 standard.

8. Sales and Certification

Article numbers are provided for each torque class.
U.S. FCC certification is not required.

Summary

The DST torque measuring system delivers high-precision torque measurement with multiple accuracy classes and rated torque options. It integrates optical speed detection, robust mechanical design with high load limits, and flexible electrical output signals. The system is suitable for demanding applications requiring precise torque and speed measurement within defined environmental and mechanical constraints. Detailed mechanical drawings and optional configurations are available upon request.

Vibration limits are not an influence to the machine. They reflect the allowed effect onto the rotor (ISO 7919-3). Parameter "n" is given in "r/min.". Weights are related to components without options like speed detection system. Please contact us for exact weight information of options. The parameters of "Flatness and concentricity tolerances rotor" are manufacturing tolerances. The supply voltage range must be given at measurement system side. Long wires can reduce the voltage level from power supply to measurement system. ©2022, ATESTEO GmbH & Co. KG, This product data sheet was created on...
