Bernstein AG
In general, inductive proximity switches consist of four basic elements: a coil, an oscillator, a threshold switch and an output stage with short-circuit protection.The oscillator generates a high frequency, electromagnetic alternating field which is emitted from the active face of the coil.Eddy currents are induced in a metal object that enters this field. These eddy currents draw energy from both the electromagnetic field and from the oscillator which is consequently attenuated.The more energy taken the closer the metal object moves towards the active face. The threshold switch switches on the output stage at a defined attenuation value.In proximity switches with a DC voltage supply, this switch is designed as an NPN transistor which switches the connected load to the negative pole or as a PNP transistor which switches the load to the positive pole. The output stage is a thyristor or a triac in AC voltage switches.

Nex Flow Air Products Corp.
electrofield meter is a small hand-held field strength meter with a digital display for measuring electrostatic charges in Volts. It perfectly combines easy operation with an accurate measuring technique. The Static Meter measures charges according to the field influence principle C: The influenced charges, caused by the electrical field, generate an alternating current proportional to the electrical field strength. The selective amplifier converts this value into the corresponding field strength or electrical potential – without withdrawing energy from the electric field over the averaged time.

Guth GmbH
The mains voltage (230V / 3 x 400V) is transformed, rectified and filtered by the HN series. The direct current output voltage is tuned by a variable transformer or regulated by a thyristor controller. With the HS and HV series the rectified mains voltage is supplied to a frequency converter, which produces a mid-frequency square wave voltage. This transformed, rectified and filtered alternating current produces the desired voltage as output, which is regulated by means of frequency variation or pulse width modulation. The equipment in the HV series supply, in addition to the high voltage output, up to 3 auxiliary outputs which can be used to supply e.g. heating, grid voltage or surge voltage.

PCE Instruments
Here you will find an insulation tester for a variety of ranges between 50 mega ohms and 2000 mega ohms. The portable manual insulation tester is used for determining insulation resistance, continuous current, alternating current and testing. With an insulation tester, measurements can be taken for different voltages, beginning with 100V up to 10,000V. Measurements meet the DIN VDE 0413 part 1 standard. The insulation tester comes with a test mechanism, clips, batteries and a carrying case. The insulation meter can be equipped for test laboratories if an optional DIN EN ISO is acquired.Measurement of insulation in cables and motor coils is vitally important for the prevention of accidents and damage to installations and is obligatory according to most codes of conduct.

At PCE Instruments you will find a power quality analyzer to measure the power in W, kWh or to analyze and measure harmonics. This power analyzer is a multi-function power analyzer device that measure precisely direct current, alternating current, AC-voltage, DC-voltage the intensity of DC or AC, phase rotation and idle, apparent and effective power. The reading of AC power is considered the real value and has a maximum range of 6000 Watts. While a reading is being taken, the polarity changes automatically, if negative values are taken then a minus sign will appear on the device display.Nowadays, power quality analyzers have many features such as, insulated current input, measurement of harmonics, AC and DC current measurement, AC and DC voltage measurement, frequency measurement, phase rotation measurement and idle, apparent and effective power measurement. All this data can also be logged and analyzed with the delivered PC-Software. Power analyzers of the type PCE PA 6000 can determine the energy in single-phase systems.Power quality analyzers of type PCE-GPA 62 allow the energy measurement in symmetrically loaded three-phase systems. Power analyzers of type PCE-PA 8000, PCE-360 and PCE-830 support professional power and energy measurements in single and three-phase systems.Apart from being used as energy-measuring devices, power analyzers like the PCE-830 can also be used for network analysis and the determination of harmonics and phase rotation. On our website you will find other power analyzers used in the field of electronics.

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.
