Applications & Information
The redundant force transducer works according to the strength measuring principle on a transverse basis to the longitudinal axis.
The SKA-30D is designed for application at conveyor scales, bin-type weighing devices, platform scales and overhead conveyor scales, but can also be used for measuring the forces applied on machine parts, levers, axles etc.
The device has been designed as a beam with a measuring cell. Due to the beam shape and two 13 mm size boreholes, all machine building requirements will be met when mounting this component. The force transfer is carried through by use of a borehole Ø 13 mm with a lowering Ø 24 mm. The measuring bridge has been arranged redundant, if failured one measuring cell or the amplifier, then the other bridge take over this one service.
The measuring cell for the strain gauge has been cast with a high-elastic compound and is thus protected against mechanical or chemical damages.
The strain gauge bridges measure the caused deformation in the measuring cell due to shear forces at the beam. An integrated amplifier gives a measuring signal between 1 and 9 mA or between 4 and 20 mA. The calibration is carried out by use of a resistor, parallel connected with a strain gauge bridge (software calibration).
The SKA-30D is assigned for the direct coupling to an automatic control or a controlling switch.
