The load pin works according to the strength measuring principle on a transverse basis to the longitudinal axis.

The SKL-30 was developed especially for use at hydraulics cylinders by work platforms, cranes and other mechanical force measurement on working platforms.

It is designed as a round bolt with two measuring cells. A groove of 4,5 mm of width and 4,0 mm of height serves for the fastening.

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 deformation caused by clipping strengths on the bolt in the measuring cell. An integrated amplifier per measuring cell gives a measuring signal between 1 and 9 mA or between 4 and 20 mA impressed current.

The calibration is carried out by use of a resistor, parallel connected with a strain gauge bridge (software calibration).

The SKL-30 is assigned for the direct coupling to an automatic control or a controlling switch.
