Mechanical Assembly
Installation Instructions:
It must be ensured that no materials (e.g. liquids, gases) from other components of the
spindle get into the torque sensor.
Before the assembly, spline drive (or square drive) must be cleaned with dissolver (e.g.
acetone) and lightly greased, no foreign particles may adhere to them. The hub must fit
corresponding to the connection.
Caution:
During the assembly inadmissibly large forces may not act on the sensor or the
mechanical connections. At small torques (< 50 N·m) connect the sensor electrically
during the assembly and observe the signal, the measurement signal may not exceed the
limit values.
Type DR-1986
The shaft of the torque sensor is designed with an inner and external square connector. The shaft is used
to transmit torque to the screwdriver.
The mechanical connection to the spindle housing occurs via a screw connection.
Type DR-1987 and DR-1988
The shaft of the torque sensor is designed with an inner and external square connector. The shaft is used
to transmit torque to the screwdriver.
The mechanical connection to the spindle housing occurs via a tooth system and a union nut.
Type DR-2124
The shaft of the torque sensor is designed with a splined shaft and tooth hub connection. The shaft is
used to transmit torque to the screwdriver.
The mechanical connection to the spindle housing occurs via a tooth system and a union nut.
