Load cell QSZF-А


QSZF-A – beam double-beat load cell upon bending.

Beam double-beat type of sensors are applied for production/updating of truck and track scales, weighing systems of vehicles, weighing systems of tans, for measuring of axial load of vehicle as well as it can apply in different electron – weighing equipment.

Due to high metrological performance the present type of sensors finds wide application in different industrial systems of weight measuring, it can apply in place of rod (columned) sensors. Housing of QSZF is made of steel with nickel coat with application of laser welding, protection class of load cell is IP68 (full dust and moisture protection).
