Abstract

1374316 Load cell BERGWERKSVERBAND GmbH 19 Jan 1972 [10 Feb 1971] 2556/72 Heading G1W A load cell comprises a pressure member 1 having a small cavity 3 filled with liquid and connected to an indicator tube 4. Pressure plates 2 or 21 may be provided either side of the pressure member, or the pressure member may be placed in direct contact with pit props or rock surfaces. The pressure member 1 may be of plastics material, suitable examples of which are given.
