ABSTRACT:
The microbalance includes a mounting having two vertically aligned elongated flexible metal tension members, the upper and lower ends of the tension members being attached to a fixed support. The attachment of one end of each of the tension members to the fixed support is carried out by a resilient tension means. A pivot crossbeam is fixedly attached to the balance beam, and the ends of the pivot beam are fixedly attached respectively to the tension members at points intermediate to the ends. Deflection of the microbalance beam is accommodated by flexure of the metal tension members.
