An air balance of automatic sensing weight type is provided to allow a worker to have complete balance by supplying a constant pressure to an air cylinder in proportion to the load value according to the weight change. In an air balance(1) of automatic sensing weight type, a control signal is supplied to a balance unit(50) so that balance between the load value of the weight goods and inside pressure of the air cylinder(11). If the raised pressure of the air cylinder inside is detected by with a pressure sensor(51), the surplus air is discharged by operation of the balance valve of balance unit, and If the decreased pressure of the air cylinder inside is detected by with a pressure sensor, the insufficient air is supplied by operation of the balance valve of balance unit. |
