Abstract: A transducer body (10) including a support having a pair of clevis halves (16, 18), and a sensor body (12; 102; 202; 242) coupled to each of the clevis halves (16, 18), the sensor body (12; 102; 202; 242) disposed between the clevis halves 16, 18 and configured to deflect with forces along two orthogonal axes. The sensor body (12; 102; 202; 242) includes a generally rigid peripheral member (22) disposed about a spaced-apart central hub (20), the central hub (20) joined to each of the clevis halves (16, 18) with the peripheral member (22) spaced apart from each clevis half. At least three flexure components (31-34; 112A-112B; 212; 251-254) couple the peripheral member 22 to the central hub 20. The flexure components (31-34; 112A-112B; 212; 251-254) are spaced-apart from each other at generally equal angle intervals about the central hub 20. The sensor body (12; 102; 202; 242) further includes a flexure assembly (51A- 51B; 115A-115B) for each of the at least some flexure components (31-34; 112A-112B; 212; 251-254) joining the flexure component (31-34; 112A-112B; 212; 251-254) to at least one of the central hub (20) and the peripheral member (22), the flexure assembly (51A- 51B; 115A-115B) being compliant for forces in a radial direction from the central hub (20) through the flexure component (31-34; 112A-112B; 212; 251-254) and to the peripheral member (22), wherein each flexure assembly (51A- 51B; 115A-115B) is configured such that forces transferred between central hub (20) and the peripheral member (22) concentrate strain at a midpoint (66) along the length of each corresponding flexure component (31-34; 112A-112B; 212; 251-254). A platform balance (300) may be provided with transducer bodies (10) as shown and described.
