<p>A stainless steel load cell (42) having a shear web (58) design suitable for use in a continuous casting environment is disclosed. Strain gauges (64) are disposed on both sides of each of the four webs (58) to detect deformation, while a wheatstone bridge (69) is provided, having thermally-compensated potentiometers (72), to balance the strain gauge output to provide a signal indicative of an applied load. The interior of the load cell is sealed on both sides with disc shaped stainless steel seal members (84). The interior of the load cell is coated with a very low durometer polymer (86) to provide the bridge (69) and strain gauges (64) with a barrier to moisture and other corrosive vapors. The load cell is enclosed by an air-tight canister that is supplied with pressurized nitrogen gas for drying purposes.</p> |
