The force transducer works according to the principle of the strength measuring in the direction of the longitudinal axis.

Tractive forces can be included among others at lifts, cranes, gondolas as well as at braced of masts, towers, platforms etc.

The force transducer ZKA-20 is listed as a thread stick (on both sides M20). This permits a simple and universal fastening. About clevis is fastening possible.

The application room for the strain gauge is protected by an aluminium tube, which is spilled with a highly elastic mass from mechanical and chemical damages.

The strain gauge bridges measuring the length change and crossways stretching (vertical and horizontal expansion) caused by pulling forces on the force transducer. An integrated amplifier provides a measuring signal of 4 - 20 mA.

The ZKA-20 is assigned for the direct coupling to an automatic control or a controlling switch.
