Task
The need often arises to guide the forces through a load cell via the central axis. Practically any design can be produced, no matter what combination of measuring range and internal diameter of the measuring element is required. The principle is based on two axially aligned annular discs that have the desired internal diameter, with three load cells spaced at 120° around their surface. These load cells have been standardized to output the same electrical signal for easy operation and combined readout by instrumentation amps. The ideal measuring range of the overall system can be achieved by a suitable choice of load cells, and this is adjusted at final calibration.
