The redundant force transducer works according to the principle of the shear force measurement crossways to the longitudinal axis.

The SKA-40D 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 chamber. Due to the beam shape and two 17,5 mm size boreholes, all machine building requirements will be met when mounting this component. The force introduction is carried through by use of a drilling M16. The measuring bridges has been arranged redundant, if failured one measuring cell or the amplifier, then the other bridge of the 2. channel take over this one service.

The application room for the strain gauges (dms) has been cast with a high-elastic compound and is thus protected against mechanical or chemical damages.

The strain gauge full bridges measures the deformation in the measuring chamber which is caused by shear forces on the beam. Ever one integrated amplifier produce the measuring signal of 4 - 20 mA.

In the unloaded state can by add-ons of the calibrating checking signal (software calibration) the nominal output current be produced. A check of the force transducer with the amplifier and the following measuring facilities is possible with that.

The SKA-40D is planned for the direct connection with an automatic control or a controlling switch.
