1. A load cell comprising, in combination:
- a hollow central measuring column subject to strains to be measured,a base section for supporting said hollow central measuring column, anda load receiving section for receiving a load at substantially one point and transmitting the load substantially uniformly to said hollow central measuring column, said load receiving section including an extension extending into the hollow portion of said hollow central measuring column to reduce the deflection of said load receiving section when load is applied to the load cell.

Abstract
A load cell having a hollow central measuring body, a base section for supporting the measuring body, and a load receiving section for receiving a load at substantially one point and transmitting the load substantially uniformly to the hollow central measuring body. The load receiving section includes an extension extending into the hollow portion of said measuring body to reduce the deflection of said load receiving section when load is applied to the load cell. The base section includes a reduced section to cause the base section to deflect under load to compensate for deflection of the load receiving section under load.

2. A load cell comprising in combination:
-
a central measuring section, a load receiving section for receiving a load at substantially one point and for transmitting the load substantially uniformly to the central measuring section, a base section for supporting said central measuring section, said base section having a reduced section to cause said base section to deflect under load to compensate for deflection of the load receiving section under load.
