Abstract
Load cell lift-off protection devices with the load to be measured applied directly to the spherical upper surface of the load cell and with locking members which are locking grooves in the load cell force introducing parts to grooves in the structure of the weighed installation.
Claims20
A load cell system configured to measure an axial load in a direction of a central axis of a load cell, the load cell system comprising
- a load cell body having a first end and a second end, the second end having a cell body groove defined therein;
- a load transmission member configured to transfer the axial load of a weighed installation to the load cell body in a direction coaxial with the central axis of the load cell, the load transmission member defining a transmission member recess configured to receive at least a part of the second end of the load cell body so that the cell body groove is substantially aligned with a transmission member groove defined in the load transmission member that is in communication with the transmission member recess;
- a first connection arrangement configured to securely attach the first end of the load cell body to a base;
- and
- one or more locking members configured to attach the second end of the load cell body to the load transmission member, opposite portions of the locking members being in part receivable in the cell body groove and the transmission member groove, respectively when the second end is received in the transmission member recess;
- wherein any one of or combination of the locking members, the cell body groove and the transmission member groove being configured to provide a margin/latitude movement allowing the load transmission member to tilt at an angle relative to the central axis of the load cell body.

A load cell system configured to measure an axial load in a direction of a central axis of a load cell, the load cell system comprising
- a load cell body having a first end and a second end, the second end having a cell body groove defined therein and a spherical or curved free end;
- a load transmission member configured to transfer the axial load of a weighed installation to the load cell body in a direction coaxial with the central axis of the load cell, the load transmission member defining a transmission member recess configured to receive at least a part of the second end of the load cell body so that the cell body groove is substantially aligned with a transmission member groove defined in the load transmission member that is in communication with the transmission member recess, the load transmission member including a contact surface that in part defines the transmission member recess;
- a first connection arrangement configured to securely attach the first end of the load cell body to a base;
- and
- one or more locking members configured to attach the second end of the load cell body to the load transmission member, opposite portions of the locking members being in part receivable in the cell body groove and the transmission member groove, respectively when the second end is received in the transmission member recess;
- wherein the spherical or curved free end surface of the second end is in contact with the contact surface when the load cell body is locked in the transmission member recess utilizing the locking members
- wherein any one of or combination of the locking members, the cell body groove and the transmission member groove being configured to provide a margin/latitude movement allowing the load transmission member to tilt at an angle relative to the central axis of the load cell body.
