Inclination spring balance
摘要:
The helical tension spring which counteracts the weight of an object on the scale pan of an inclination balance is fixedly attached to one arm of the balance beam to avoid friction in the connection between the spring and the beam. The attachment permits the spring position to be adjusted along the beam and the effective length of the spring to be adjusted. The weighing errors resulting from buckling of the spring are compensated by a suitably modified scale from which the weight is read.
