Data sheet F0xS

Product catalog summary

Overview: This document is a technical data sheet for the FxiS and FxeS series torque measuring systems by ATESTEO GmbH & Co. KG, created on June 17, 2025. It provides detailed specifications, mechanical dimensions, speed measuring systems, and other technical data for these products.

Specifications:

Accuracy Class: Standard accuracy is ≤±0.05%, with an extended accuracy option of ≤±0.03%.
Rated Torque (Mdn): Models range from 50 Nm to 1,000 Nm.
Outputs: Include Frequency (RS422), Voltage, Current, CAN bus, and Alert.
Mechanical Dimensions: Rotor outer diameter is 94 mm, with varying lengths and pitch circle diameters.

Speed Measuring Systems:

Integrated speed detection is not available; optional inductive or optical systems can be used.
Maximum speeds reach up to 30,000 rpm with inductive encoders.

Torque Accuracy:

Frequency and CAN outputs have an accuracy of ≤±0.05%, with options for ≤±0.03% accuracy.
Voltage and Current outputs have an accuracy of ≤±0.10%.

Temperature Ranges:

Nominal temperature range for the rotor is 0 to 80°C; for the stator, it varies between 0 to 70°C and 0 to 80°C depending on the model.
Operating and storage temperature ranges are specified for both rotor and stator.

Mechanical Values:

Specifications include torsional, axial, radial, and bending stiffness for different models.
Load limits, including limit torque and breaking torque, are detailed.

Additional Information:

Protection class for both rotor and stator is IP54.
Power supply requirements include a nominal supply of 24 V DC.
Remarks provide additional context on nominal torque, dimensions, and temperature ranges.

Key Sections:

Load Limits: Valid only if no other loads are present. Combined loads reaching 100% result in a maximum error of 0.3% of nominal torque. Additional loads reduce limit and break torque.
Vibration Limits: Indicate permissible impact on the rotor as per ISO 7919-3, measured in rotations per minute (r/min).
Weights: Provided weights exclude optional features like speed detection systems. Contact ATESTEO for precise weights with options.
Flatness and Concentricity Tolerances: Manufacturing tolerances for rotor's flatness and concentricity.
Supply Voltage: Must be specified at the measurement system side. Long wires can decrease voltage level from power supply to measurement system.

Drawings: Includes multiple drawings for different systems and components, such as the F0iS and F0eS systems, rotors, and stators, with configurations like SPD_IND and SPD_OPT.
