4.9 Advice for assembly of the DATAFLEX
®
torque measuring shaft
Insulation
All DATAFLEX
®
measuring shafts of type 85 correspond to the Protection IP50 according to DIN EN 60529.
Maintenance
The DATAFLEX
®
measuring shaft is maintenance-free. Lubrication or cleaning is not necessary.
Calibration
The unit is supplied with a calibration sheet. We recommend to inspect the calibration every six months.
4.10 Technical description
1. General description
The overall measuring electronics is installed in the fixed housing so that additional devices for signal processing
are not necessary. The measuring shaft can be wired either by the terminal housing DF2 available as accessories
or manually by a 12-pole coupling (type Binder series 432) (pin configuration see table 7). The measuring system
has three measuring terminals which the analogous terminal figures for torque and speed can be measured on.
Two digital terminals show the current operating condition, while two digital inputs can be used for calibration.

The measuring shaft should initially be switched on when all of the connections have been
properly connected. After it has been switched on for the first time the measuring shaft will
take around 5 minutes until this warm up phase is finished and the measurement device will
have its standard accuracy.
