TTS Transfer Torque Wrench For Calibration

The TTS transfer torque wrench is used to check and calibrate torque wrench calibration equipment. It is precisely coordinated to the requirements of these calibrations, such as those prescribed in Guideline DKD-R 3-7.

Because of the particular type of torque generation produced by a torque wrench, the extreme resistance of the TTS to bending moments is a crucial criterion.

German Calibration Service (DAkkS) calibration as stipulated in DKD Guideline DKD-R 3-7 documents the stringent demands by which the TTS must be measured as a transfer standard.

A calibration certificate in accordance with guideline DKD-R 3-7 has to be ordered separately.

Also among the components supplied are a carrying case and an external square adapter in a standard size. Square adapters in other sizes are available as accessories.

Precistion Coupling for HBM Torque Transducers

Precision couplings for HBM torque transducers

Couplings for torque transducers are a key accessory. A torque flange is a precision transducer that enables very small uncertainties of measurement to be attained. However, certain requirements need to be met to achieve this. One of the most important is to minimize the parasitic loads affecting the transducer which, among other things, result from alignment errors in the drive train.

Offset compensation is the main task of offset couplings

Besides precise torque transfer, the main task of a coupling consists of offset compensation. In nearly all practical applications, these offsets occur between the driving and the driven side. They result from dimensional tolerances in the components used as well as from external influences such as temperature that prevent complete elimination of the offsets.

Your Selection Guide for Couplings & Mounting Parts

Which coupling is the right one?

A torque flange is a precision transducer that enables very small uncertainties of measurement to be attained. However, to achieve this special requirements need to be met. It is most important to minimize the parasitic loads affecting the transducer which, among other things, result from alignment errors in the drive train. A radial parallel offset of the shaft ends installed on the measurement flange generates a radial force and a bending moment affecting the transducer. A radial angular offset results in a bending moment while an axial offset causes both an axial force and a bending moment.

HBM Build-Up Systems: Capacities from 60 kN to 15 MN

The series BU18 transfer devices comprise a three-ring torsion force, with transducers mounted parallelly. The three individual sensors can be electrically connected in parallel. Alternatively, they can also be connected to one amplifier input each.
