Data sheet DF4 dual

Product catalog summary

Overview: The DF4 dual torque measuring system by ATESTEO GmbH & Co. KG is a sophisticated tool designed for precise torque measurement. This document provides detailed specifications, mechanical dimensions, speed measuring systems, temperature ranges, mechanical values, and additional technical data.

Specifications: The DF4 system boasts an accuracy class of ≤±0.04% with torque options of 4,000 Nm and 5,000 Nm. It supports output types such as frequency (RS422), voltage, and CAN bus, and is suitable for rotating technology with optional speed detection systems.

Mechanical Dimensions: The rotor features an outer diameter of 187 mm and a length of 50 mm, with a pitch circle diameter of 155.5 mm. It can operate at speeds up to 15,000 rpm, extendable to 17,000 rpm with enhanced speed capabilities.

Speed Measuring Systems: Options include magnetic and magneto-resistive speed detection, with the latter supporting speeds up to 8,000 rpm and a resolution of 0.077°.

Temperature Ranges: The rotor and stator have a nominal temperature range of 0 to 80°C and an operating range of -20 to 85°C. The TCU operates within 0 to 70°C nominally and -20 to 70°C operationally.

Mechanical Values: Torsional stiffness values are 1,639 kNm/rad and 1,937 kNm/rad, with angles of twist at Mdn of 0.140° and 0.148°. The system also specifies axial, radial, and bending stiffness.

Miscellaneous: The system is IP54 protected and compatible with TCU5 evaluation units, featuring a CAN bus type of 2B. Constructed from steel, it has a measuring range related to Mdn of 110%.

Sales Information: The DF4 dual system's article number is 10016144, and it lacks a U.S. FCC certificate.

Specifications and Attributes:

Pitch Circle Diameter: Consistent at input and output sides, with detailed drawings available.
Linearity: Achievable with positive and negative sensitivity values.
Reference Planes: Detailed in product drawings.
Temperature Range: No condensation allowed; temperature relates to the housing ground point.
Load Limits: Valid without simultaneous loads; maximum error is 0.3% of nominal torque if loads sum to 100%.

Additional Information:

Vibration Limits: As per ISO 7919-3 for rotor effects.
Weights: Provided for components without optional systems; contact for exact weights.
Flatness and Concentricity Tolerances: Manufacturing tolerances for rotor.
Supply Voltage: Specified at the measurement system side; long wires may reduce voltage levels.

Drawings and Contact Information:

Includes various drawings for DF4 systems, rotors, and stators.
