Abstract
A base assembly for a beam balance instrument includes a box-like, open bottom base of lightweight sheet metal having an elongated slot in its upper wall, and a reinforcing strip or bar inlaid into the slot for rigidly supporting parts of the balance. The reinforcing strip is thicker and bulkier than the remainder of the base, and the fulcrum which pivotally supports the beam above the base is rigidly fastened on the strip, as is the sensor for detecting tilting of the beam in response to an applied force, and the bellows if the balance instrument is of the type used in measuring pressure variations.
Claims15
A base support assembly for a beam balance instrument, comprising:
- a box-like chassis of sheet material having an upper wall and side walls depending downwardly from the upper wall;
- support means mounted on the upper wall of the chassis for supporting a balance beam above the upper wall;
- the chassis upper wall having an elongated slot;
- and
- said support means comprising a reinforcing strip member mounted in said slot, said strip member being of thickness greater than said sheet material forming said chassis, and mounting means for rigidly mounting a fulcrum for pivotally supporting the beam on said strip member and for rigidly mounting sensor means for detecting tilting of the beam in response to an applied force on said strip member.
