The force transducer works according to the strength measuring principle on a transverse basis to the longitudinal axis.

Got to the PBB-28A special for measuring small strengths (quality control, weight and filling level determination, ...) to robot, handling and medical engineering develops.

It is executed as a beam with an open chamber. The beam shape and two boreholes with 8,4 mm of diameters permit an assembly suitable for mechanical engineerings. The strength introduction is carried out via a screw thread M8.

This one in the chamber applizierte strain gauge is spilled with a very elastic mass and protected so from mechanical and chemical damages.

The strain gauge bridges measure the deformation caused by bend strengths on the beam. An integrated amplifier 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 PBB-28A is assigned for the direct coupling to an automatic control or a controlling switch.
