Fixing the housing

 

 

 

 

The housing must be protected from rotation. For that purpose there is a thread size M4 at 
the bottom side. Please make absolutely sure to avoid a rigid fixing of the housing!

 

 

 

 

Opening the housing is not required and may cause damage to the measuring shaft.

 

 
 

 

Degree of protection 

All DATAFLEX

®

 measuring shafts type 70 correspond to protection class IP51 according to DIN EN 60529. 

 
 

 

Maintenance 

The DATAFLEX

®

 measuring shaft is maintenance-free. Lubrication or cleaning is not necessary. 

 
 

 

Calibration 

The transducer is calibrated when being supplied. We recommend an annual inspection of the calibration. 

 
 
 
 

 

1. General description 

 
The measuring shafts type DATAFLEX

®

 70 are provided with wire strain gauges (DMS) the signals of which are 

transmitted contactless. 
In addition, a two-channel shaft encoder provides two speed signals shifted by 90 degrees. Each signal has a 
resolution of 450 periods per revolution. The measuring shaft is connected to the connection housing DF2 via the 
connection cable which is available as an accessory. 
 

 

The measuring shaft should not be switched on before all connections have been properly 
connected. After initial switch-on the measuring shaft needs about 5 minutes until the 
warm-up period is finished and the measurement device has its standard accuracy.
