1. General description
The measuring shafts type DATAFLEX
®
42 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 720 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.
