Abstract

A weigh module (100) comprises a load cell (4), a supporting member (1) and a guiding arrangement. The supporting member (1) comprises a receiving hole (13) extending vertically and through the supporting member (1). The guiding arrangement comprises a connecting member (23) and two parallel inner faces (611, 612) defined in the receiving hole (13). One end of the connecting member (23) is fixed to the load cell (4) and another end of the connecting member (23) extends into the receiving hole (13). The connecting member (23) cooperates with the two inner faces (611, 612) whereby the supporting member (1) can substantially move in a direction parallel with the inner faces (611, 612).
