Speed Pick-up
SU63
The Validyne SU63 is an AC inductive speed pick-up used for RPM measurement on high-speed rotating equipment. The SU63 is a tightly-wound coil with a laminated core that can be conveniently mounted on rotating equipment so that the magnetic field of a magnetized nut or part passes through the coil windings. The moving magnetic field produces a voltage within the coil proportional to its rate of change and the strength of the permanent magnetized part. The frequency of this inductive voltage spike is fed into an oscilloscope or counter to determine RPM.

Multi-Spectral UV/Laser Range Stimulator
Phantom™
The Phantom is a long-range laser and ultraviolet (UV) stimulator capable of testing aircraft electro-optical sensor suites up to 5 km. Phantom can operate as an independent laser and/or UV stimulator or can be integrated with our other electro-optical and radio frequency range systems (see GTESS and PRTS). The Phantom provides both a laser threat and a synchronized temporal missile plume signature to stimulate both the aircraft’s laser and missile warning systems. Training aircrew to counter maneuver a Laser Beam Riders (LBR) threat is considered essential to survival and in-air training. The Phantom can be deployed either on a shoulder or tripod mount.

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.
