Description
当該センサ装置が、地面圧縮ローラの(フレーム側の)搭載配電網から独立した電気エネルギー供給を受ける点にある。例えば、当該センサ装置は、当該センサ装置が電気エネルギーの供給を受けるバッテリーを有していてよい。さらにまた、当該センサ装置の当該電気エネルギー供給を保証するその他の電気エネルギー貯蔵装置が設けられていてもよい。本発明による当該電気エネルギー貯蔵装置は、当該センサ装置と共に直接に当該ローラドラムに取り付けられているために、損傷を生じやすいケーブル接続線の布設は不要である。したがって、とりわけ、当該センサ装置の当該電気エネルギー供給は、当該定置マシンフレームと当該回転ローラとの間のケーブル接続から独立している。たとえ地面圧縮ローラが搭載配電網又はその他の負荷装置用のさらに別の電気エネルギー供給源を有していようとも、当該センサ装置用の本発明による電気エネルギー供給はそれらとは独立して形成されている。
