Force Sensor KM38Nominal force ranges 1kN, 2kN, 5kN, 10kN, 20kN

Dimensions

DescriptionThe minature force sensor KM38 is exceptionally suitable for measuring preload of bolts on account of its flat construction and its through hole. But the through hole 7mm is also suitable for introduction of a force transmission. With a spherical cap the force transmission can be centered and made free of lateral force .Through the introduction of half liners or prisms these force sensors can be adapted to the measurement of rolling forces.

The three M2.5 thread holes on the bottom side permit the attachment of the sensor or the fitting of a prism.

Load Cell KA105Nominal load ranges (compression) 10t, 25t, 40t, 60t, 100t

The compression load cell KA105 is a fully welded, hermetically sealed four pillar construction. It is thus mostly unsensitive to excentric load.Despite its high load capacity of up to 100t it is only 185mm high.Due to its geometry with a spherical cap and an even bottom surface the compression load cell can also be used for calibration of high load presses and for construction of automotive and rail-car scales.A central thread and a centering colllar on the bottom side of the sensor allows correct mounting of the sensor.
