1 VIBRATION GENERATOR - STANDARD Provides mechanical oscillations when given input signals from a signal generator. The frequency response encompasses the whole of the audio spectrum and beyond. Electrical input via a pair of 4mm shielded sockets. The oscillating mechanical output is available through a shaft at the top with a screw for attaching apparatus such as Resonance (Chladni) Plates. Cat No. Description Price Per SWA-850-100 Vibration Generator - Standard 75.78 ea. 2 VIBRATION GENERATOR - SUPERIOR A top quality vibration generator for producing mechanical vibrations when used with a signal generator. For experiments in producing standing waves on a string or elastic cord to demonstrate resonant frequency, harmonics, nodes and anti- nodes. Also for use in experiments with resonance in springs, Chladni plates etc. The design includes two 4mm safety sockets for signal input and the unit is fuse-protected and lockable, to protect moving parts while changing accessories. A string holder, mounting post, and a spare fuse are included with the apparatus. Frequency of vibration ranges from 0.1 Hz to 5 kHz, with amplitudes up to 7mm at the low end of the frequency range. The Vibration Generator may be used sitting upright, on its side, or inclined e.g. on an OHP. Maximum input: 6 V / 1 A Impedance: 8 Ohms Dimensions: 100mm diameter x 120 mm Weight: 1.2 kg Cat No. Description Price Per SWA-870-100 Vibration Generator 147.63 ea. 3 VIBRATION GENERATOR - 3B SCIENTIFIC Housed in a robust plastic case with a vertically protruding mounting pin with a 4mm socket for attaching accessories (Chladni plates, resonance wire, rubber band etc.). Including a holder for stand rod (up to 8mm dia.) on the rear side of the apparatus for the demonstration of standing waves in a coil spring. The generator is equipped with overload protection. Frequency range: 0 up to 20 kHz. Size: 200 x 160 x 70mm. Cat No. Description Price Per SWA-900-100 3B Scientific Vibration Generator 213.38 ea. 4 RESONANCE (CHLADNI) PLATES Metal Chladni plates, for generating acoustically excited figures using a vibration generator connected to a signal generator, and material such as fine dry sand to demonstrate the patterns - as in the experiments carried out by Chladni. The centre has a 4mm plug pin for attachment to a Vibration Generator. Available as round or square plates. Dimensions: Square plate 200 x 200 mm; Round plate 200 mm diameter. Cat No. Description Price Per SWA-250-100 Resonance (Chladni) Plate - Round 14.08 ea. SWA-250-150 Resonance (Chladni) Plate - Square 10.60 ea. 5 LONGITUDINAL WAVE DEMONSTRATOR Accessory for vibration generator SWA-900-100 for demonstrating standing longitudinal waves in a coil spring. Consists of angled stand rod, coil spring and connector pin for attachment of the spring to the Vibration Generator (Superior). Cat No. Description Price Per SWA-920-100 Logitudinal Wave Demonstration 60.80 ea. 6 RESONANCE WIRE RING For demonstrating the vibration knots in determination of different frequencies. Wire ring with 4mm plug for connection to the Vibration Generator (Superior). Diameter: 290mm. Cat No. Description Price Per SWA-940-100 Resonance Wire Ring 31.42 ea.
