B&K Type 4826 Exciter

B&K Type 4826 Exciter

With force ratings up to 200 N (45 lbf) for Type 4825 and 400 N (90 lbf) for Type 4826, these exciters are ideal where payloads require high-precision excitation in single- or multi-point setups. Strong and versatile, they are used for a variety of applications, such as testing of engines, body-in-white on passenger cars and small trucks, and aerospace structures.

Description

As light and compact as Type 4824, these modal exciters are much more powerful. They combine a wide frequency range (DC – 5000 Hz) and up to 25.4 mm (1 in) of displacement for improved performance at low frequencies. Suitable for impulse, sine and random signals, Types 4825 and 4826 can be used in SISO and SIMO tests of engines and other small mechanical components, as well as in MISO and MIMO tests of large devices.
