The KL20 belt sensor is suitable for measuring tensile forces in belts up to 20 mm wide and 1.5 mm thick. Two cylindrical pins (Ø2 mm x 31 mm) are used to apply the force. The belt sensor is only 4 mm thick and weighs only 7 g. This makes it easy to integrate into the straps of bags, backpacks, or sports equipment. Elastic straps also allow the creation of chest straps for measuring chest movement or displacement/angle sensors for detecting limb flexion. The KL20 belt sensor is designed for a nominal force of 100 N and can withstand a working force of up to 500 N.

The belt sensor is suitable for installation as a connecting link between two belts or as a force sensor within an undivided belt. When the belt sensor is mounted within a single belt, the sensitivity is approximately 30-50% higher than the characteristic value specified in the test report when mounted “in series” between two individual belts. The sensitivity of a single belt depends on the belt thickness and flexibility and should be determined individually for each belt used.

The KL20 belt sensor is fully encapsulated and resistant to light splash water.
