Large-Displacement Low-Frequence Vibration System
9363-LN-100
King Design Industrial Co., Ltd.
This tester is designed to assess the damage made to product packaging and internal objects caused from transporting environment; to discover the packaging flaw and product’s early failure from a long-term cumulative vibration fatigue; avoid man-made transporting damage and improve product’s reliability and quality of delivered products. With the use of high-performance foot absorber, the resonance effect to floor caused by the bounce test may be waived; and can reduce the pile’s destruction to industrial plants. Two displays can make comparative display on both frequency and rpm at the same time; thus no need to switch in order to read these two values. The dual-control mode of time accumulator and counter can avoid human error resulting from the conversion. Easy to operate; no need for complicate training program.

Site Vibration And Noise Testing
Response Dynamics Vibration Engineering, Inc.
Effective vibration isolation is critical to the performance of many systems. It is often much more challenging than expected because the structural dynamics of the supporting structure, and the isolated structure, also affect the isolation performance. Isolation resonances can often create other vibration problems and confound an engineering team. We have successfully designed vibration isolation into countless systems over the years using unique custom solutions as well as adapting standard components and applying them properly to the design.

HV AC Voltage Test Systems
Fivestar HV Testing Equipment Co., Ltd.
FSHV offers three different types of AC voltage test systems, the conventional type is AC test transformer design, mainly for testing objects of medium & low capacitance products, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers). Another is AC resonant test systems, according to series resonance circuit XL=XC (2πfL=1/2πfC), by setting F frequency of power supply or L inductance of reactor, generate a pure sinusoidal waveform of the test voltage, and the required input power is only 1/Q. Variable frequency type operates in a frequency range from 20Hz to 300Hz, ideal for field commissioning test of power cables and GIS/GIL. Variable inductance type outputs continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.

Industrial Damper Systems
1206
The 1206 Industrial Damper System has proven itself in the paper industry for over 15 years in North America and Europe. An Industrial Damper is placed against each end of a calendar roll or yankee roll where the normal roll position presses the damper piston to half of its 1.75 in stroke. Machine users report decreases in resonant vibration which has allowed machine speeds to be increased by up to 30%. The 1206 Industrial Damper System will decrease machine vibration and allow increased throughput in any application where machine performance is being limited by resonant responses in the 1-100 Hz range. Lightly damped machines such as paper and plastic film production are the best candidates.

Dielectric Resonator Oscillators
Dielectric resonator oscillators (DRO) are free running oscillators that utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals with excellent frequency stability. In addition, these oscillators are equipped with an internal voltage regulator that further improves the frequency stability by isolating the external bias pushing and modulation. In general, these oscillators are fixed. However, a small mechanical or electrical tuning range can be achieved by use of a self-locking screw or an integrated Varactor diode. The standard offering covers the frequency range of 2 to 40 GHz. While standard models are equipped with female SMA and K connectors at the RF port, other RF interface options are also available.
