It is excellently suited for testing tasks in quality assurance as well as in material testing. Inward and outward force transmission are arranged centrically. Under loading the force transmission brackets are moved parallel. Like the KD40s the force sensor KD24S is constructed as a multi-range sensor. The accuracy of 0.1 % is already reached at an output of 0.5 mV/V. Sensors from 2 to 20N can be operated with 4 times and sensors from 50 to 100N with two times their nominal force range. It is recommended to fix the sensor cable side (bottom side on picture) on the non-moving side of force transmission. Dimensions

Nominal force ranges ±2N, ±10N, ±20N, ±50N, ±100N , ±500N, ±1000N, ±2000N The force sensor KD40S is very well suited for testing tasks in quality assurance as well as in materials testing due to its compact construction. Inward and outward force transmission are arranged centrically. The force sensors KD40S up to 100N are constructed as multi-range sensors. The accuracy of 0.1 % is already reached at an rated output of 0.5 mV/V. This means that the zero-point stability is 4 times higher than in a sensor with the nominal output of 2 mV/V. The force sensor KD40S can be used up to an output signal of 2 mV/V or four times the specified nominal force. The force sensor KD40S (up to 100 N) should be installed in such way that the outgoing cables are assigned to the immobile side of the measuring construction. Thus forces from the connecting cable do not have an influence on measurement results. From 500N upwards the force sensors KD40s have a nominal rated output of 1.0mV/V. They can safely be overloaded up to 1.5x their nominal force. The cable output can be found in the middle of the two force transmission beams. For force transfer there exists one thread M5 (up to 100N) and M6 (from 500N) in the top and bottom side of the force sensor. Additionally there is a thread M6 (from 500N) that can be used as anti-twist protection. The force sensor from a nominal force of 1000N has a height of 34 mm.
