Supmeter Shovel Loader Weigher, High Sampling Frequency 400Hz Weighing System, Wheel Loader Scales

SUPMETER Shovel Loader Weigher, High Sampling Frequency 400Hz Weighing System, Wheel Loader Scales

Wheel Loader Weigher is a dynamic weighing and auto-totalizing equipment installed on wheel loader.

When the lift-arm of wheel loader lifted to a certain height, the position sensor will trigger the weighing process, and the weighing indicator will collect the oil pressure signal from lower and upper oil chambers of arm-lifting oil cylinder. After signal processing and compensating, Single-bucket-loading -weight will be got and totalized to Totalized Loading Weight automatically. The operator can judge if the present Single-bucket-loading-weight is valid according to the alarm messages, and confirm the last bucket's loading weight according to the negative deviation value.

Each set contain:

1pcs Weighing indicator with thermal printer.

1pcs Position sensor.

2pcs Oil pressure sensors.

2pcs Plate type three-way joints.

1pcs Mounting fitting.

Applicable Wheel Loaders

Suitable for the wheel loader series with loading capacity 1~12t.
