Kistler Multicomponent Dynamometers

Kistler 9257A

Kistler 9255B


The Kistler multicomponent dynamometer consists of four three-component force sensors fitted under high preload between a baseplate and a top plate. Each sensor contains three pairs of quartz plates, one sensitive to pressure in the z direction and the other two responding to shear in the x and y directions respectively. The force components are measured practically without displacement. The outputs of the four built-in force sensors are connected inside the dynamometer in a way to allow multicomponent measurements of forces and moments to be performed. The eight output signals are available at the 9-conductor flange sockets. Different dynamometers available in AMPL range from different sizes and sensitivity, such as the dynamometer 9257A with the maximum force range of 7.5 kN for x and y axes and 15 kN for the z axis; the dynamometer 9255B and 9067’s range is 20 kN for x and y axes and 40 kN for z axis.


JR3 Multi-Axis Load Cell

JRS 6 Axes Load Cell


The JR3 multi-axis load cell, also commonly known as a 6 degree-of-freedom force-torque sensor, is a cylindrically shaped monolithic aluminum device (optionally stainless steel or titanium) containing analog and digital electronics systems. Foil strain gages bonded to multiple internal load-bearing elements sense the loads imposed on the sensor. The strain gage signals are amplified and combined to produce analog representations of the forces along three orthogonal axes (x,y and z) as well as the moments or torques about those axes.
