SU63 -
Validyne Engineering
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.

Weshine Electric Manufacturing Co., Ltd
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores.

Osborne Transformer Corp.
Osborne Quasi Square Wave Constant Voltage Transformers are used to regulate output voltages for applications that have varying input voltages. When used with a rectifier conversion circuit, these units provide an elegant design approach to voltage regulation. Osborne achieves this innovative approach by partnering the constant voltage transformer with an auxiliary resonant capacitor winding. The result is a unique (though time honored) technology that offers reliability, performance, and cost advantages over other styles of voltage regulation.

Hangzhou Hopoo Optoelectronics Technology Co., Ltd
This system uses the method of fixing the detector and rotating the lamp under test to measure the light intensity distribution of the light source or lamp under test in all directions in the space. The main shaft and the lamp shaft adopt the conductive slip ring with precious metal fiber point brush structure, which can run 360 degrees continuously without backlash for measurement. There is no need to rotate back and forth to prevent winding and never winding. According to the requirements of the measuring lamps, the system can be configured as a double-column B-β test scheme or a single-column C-γ test scheme. Used for LED lamps (semiconductor lighting), road lamps, floodlights, indoor lamps, outdoor lamps, etc. and LED, energy-saving lamps, fluorescent lamps, incandescent lamps, HID lamps and other light sources of spatial luminosity distribution

Magtrol Inc.
Magtrol’s 4 quadrant motorized dynamometers provides expanded testing flexibility over a typical braking dynamometer. With the ability to bring the motor under test (MUT) to synchronous RPM before beginning a test, repeatability is improved. Since the motor windings are at ambient temperature before starting a ramp test, wattage is more consistent.
