Kistler offers dynamometers based on piezoelectric measurement technology for test and measurement solutions.

Dynamometers for measurement technology test solutions: wide application range and easy handling

Our dynamometers are used for a vast range of test applications – one of many examples is spaceflight, where they measure the thrust forces in rocket or satellite engines so the engines can be characterized. Force dynamometers from Kistler are based on piezoelectric measurement technology. They are designed so they are immediately ready to use. No in-situ calibration is needed – so handling is made much simpler. The test object is mounted directly on the dynamometer, which measures the reaction forces.

Four 3-component force sensors are built into one dynamometer. The individual signals provide the three components of the force vector (Fx, Fy, Fz), and moments Mx, My and Mz can be determined. This is not possible with one single force sensor.

When piezoelectric force sensors are applied consistently, the result is an enormous measurement range covering several decades. One key aim of development work on dynamometers is to attain high natural frequencies so users can benefit from the largest possible signal bandwidth.

For special applications – such as micro-vibration measurements – Kistler offers dynamometers with a ceramic top plate : this significantly increases the dynamometer’s natural frequency and expands its usable bandwidth. Most of our dynamometers designed for test solutions have an IP67 protection rating. This makes them suitable for operation in humid environments or short-term use in freshwater. We also offer special versions for use in vacuum chambers – e.g. for tests on spacecraft.

Typical applications for dynamometers

High insulating connection cables for dynamometer

Dynamometers for test solutions in measurement technology – from the sub-newton range to 60 kN

Dynamometers for universal use are based on four piezoelectric force sensors that each capture forces x,y and z. They can cover force ranges of up to 60 kN, and Kistler offers top plates with dimensions of up to 400x600 mm; the plate size will vary depending on the measuring range.

For universal use: the handy 9257B multicomponent dynamometer features a measuring range of up to 10 kN – making it ideal for many applications.

Robust: optimized for large forces, the 9255C dynamometer is equipped with a robust platform. It measures forces of up to 60 kN.

Large: the 9253B22/23 dynamometer features a top plate measuring 400x600 mm to ensure safe and reliable mounting when larger test objects are involved. The measuring platform is mounted through the center of the four feet. Although the base plate is used on all other dynamometers, it is not used in this case.

To implement customers' individual requirements: the 9366CC set from Kistler offers a ready-to-connect, preloaded and calibrated multicomponent kit so users can build their own measuring platforms in line with their specific requirements. The sensors are freely movable on the table. With this kit, setups can be built with top plate sizes ranging from 300x300 mm to 900x900 mm.

Temperature-compensated dynamometers for measurement technology tests: from millinewtons to 30 kN

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.

The 9236A high-frequency dynamometer is specifically designed for test and measurement applications in vacuum chambers and cleanrooms. It features a ceramic top plate to ensure maximum rigidity, giving it an exceptionally high natural frequency. Thanks to its high resolution, the 9236A can measure the most minute dynamic changes in very small forces (up to 500 N). Two different versions are available: the 9236A1 dynamometer with a 260x260 mm clamping surface, and the 9236A2 model with a clamping surface measuring 400x400 mm.
