OIML - certified belt scales
Hense Wägetechnik offers 2 types of OIML approved scales. The belt scale BS211 mainly consists of a rigid outer frame with maintenance free bearings. The inner frame supports the weighing idler and leads the resulting force in a precise tension load cell. The output signal of the OIML approved load sensor is amplified and the multiplied with the speed signal of the belt speed sensor.
The “class1” version BS 143 is used for a different amount of applications, where an high accuracy is required and is especially suitable for approved applications. The weighframe is tailor made to fit in the conveyor, so that a minimum of modifications of the conveyor is required.
The belt speed is measured via an incremental encoder at the turn drum.
Both systems require a gravimetric belt tension system to achieve the approval.
