Used UNHOLTZ-DICKIE 20H #9014176 for sale

UNHOLTZ-DICKIE 20H is a type of electrodynamic shaker used for vibration testing in research and engineering. This device is one of the most common vibration test systems used in laboratory settings, and is capable of operating over a wide frequency range. It is often used in the evaluation of product designs, to induce fatigue, and evaluate safety standards too. The most prominent feature of 20H is its 20-kN (4452-pound) force capacity. This allows the shaker to generate very large forces and is often used to apply large vibrational forces with controlled frequency and displacement to specimen specimens. UNHOLTZ-DICKIE 20H operates from DC to 15,000 Hz, with a peak-to-peak sinusoidal displacement range of up to 11 millimeters. To ensure accurate measurements, 20H is equipped with a range of specialized components and carefully calibrated feedback and control loops. This includes its electromagnetic shaker, drive amplifier, controller, and digital load cell. The drive amplifier provides a controlled AC current to the shaker, while the controller works together with the digital load cell to monitor and regulate the load and displacement induced by the shaker. The load cell should be regularly calibrated in order to ensure that the force or displacement levels remain within specification. UNHOLTZ-DICKIE 20H sits on rubber-mounted footings that are designed to isolate most of the transmitted vibrations. This allows for a greater range of vibration amplitudes and frequencies by ensuring that the base and the shaker system are isolated from external vibration sources. In addition to these components, 20H has a number of supporting accessories, from screw-in mass dampers to weights, isolators, connectors, clamps, and connectors. These are often used to tailor the vibration levels, and should be regularly checked to ensure that they are in good condition. The mass dampers and isolators should also be regularly serviced to ensure optimum performance. In summary, UNHOLTZ-DICKIE 20H is a powerful and reliable laboratory shaker that can produce very large forces to test the structural integrity of various products. This device is capable of generating vibrations from 0 to 15,000 Hz, with a peak-to-peak sinusoidal displacement range of up to 11 millimeters. Its components are carefully engineered and designed to ensure accurate measurements and controlled vibration levels, while its accessories allow for precise adjustment of the vibrational force and displacement.
