Piezoelectric measurement technology is ideal when the test signals to be captured set high requirements for sensitivity and dynamics. Temperature fluctuations that can occur during measurements usually cause undesirable signal drift. A stationary dynamometer with horizontal preload – known as a temperature-compensated dynamometer – largely eliminates the negative influences of heat generation, so drift is minimized. This allows accurate measurements of processes involving high levels of heat generation and/or temperature changes.
Kistler offers temperature-compensated dynamometers for the entire measuring range up to 30 kN. Because their rigidity and mass are optimized, these dynamometers offer extremely high natural frequencies.
MicroDyn: thanks to its exceptionally high rigidity and natural frequency of over 15 kHz, the 9109AA is our most favored solution to overcome the special challenges of measuring highly dynamic forces. These characteristics allow analysis of forces ranging from a few mN to 500 N. The special design of this device also allows users to calculate the moment Mz in the center of the dynamometer, based on the individual force components.
MiniDyn: the MiniDyn series comprises the 9119AA1 and 9119AA2 versions. The 9119AA1, which attains natural frequencies of over 6 kHz, is suitable for applications with forces of less than 1 N to 4 kN. The 9119AA2 features a somewhat larger clamping surface (107x80 mm) as well as natural frequencies in excess of 4 kHz in all three directions.
MidiDyn: the MidiDyn 9129AA multicomponent dynamometer is Kistler's best-selling dynamometer model. With a wide measuring range (from –10 kN to 10 kN) and a clamping surface of 150x107 mm, this is the all-rounder in our family of dynamometers.
MaxiDyn: the compact and robust 9139AA multicomponent dynamometer features a wide measuring range (up to 30 kN) to ensure precise measurements.
