Product catalog summary

Product Overview
This document is a product data sheet for the FxiS / FxeS series by ATESTEO GmbH & Co. KG, created on March 16, 2026. It outlines the technical specifications and operational parameters of the torque measuring systems, emphasizing that the information is subject to change as the products are further developed.

Performance and Accuracy

Linearity Deviation: Varies with frequency and CAN outputs, with specific values for different torque ranges
Temperature Influence: Detailed for frequency, CAN, voltage, and current outputs, with specific deviations per 10K temperature change
Long-term Drift: Voltage output <1.0 mV, Current output <0.80 µA over 48 hours

Mechanical and Environmental Parameters

Temperature Ranges: Nominal, operating, and storage temperature ranges specified for rotor, stator, and TCU
Load Limits: Detailed for limit torque, breaking torque, axial and lateral limit forces, and bending limit torque
Mechanical Shock and Vibration: Specifications according to EN 60068-2-27 and EN 60068-2-6

Additional Features

Protection Class: IP54 for both rotor and stator
Power Supply: Nominal supply of 24 V DC, with a range of 23-25 V DC
Miscellaneous: Includes information on material, measuring range, and compatible evaluation units

Remarks and Information

Details on nominal torque, second torque range, mechanical dimensions, and load limits are provided, with references to drawings for precise measurements.
Temperature ranges specify no condensation allowed, and load limits are valid only if no other loads occur simultaneously.

Flatness and Concentricity Tolerances: The document specifies that the flatness and concentricity tolerances for the rotor are manufacturing tolerances, indicating precision requirements during production.

Supply Voltage: It is crucial to provide the supply voltage range at the measurement system side. The document notes that long wires can lead to a reduction in voltage levels from the power supply to the measurement system.
