Human Exposure Measurements to Luminaries
Through different ways of coupling between luminaries and humans, a level of exposure of a person to electromagnetic fields can be derived. One part of the exposure is based on capacitive coupling between lighting equipment and person. This creates induced internal electric field that must be evaluated using an EMI receiver and a Van Der Hoofden test head.

Horn Antennas
Horn antennas can be used for emissions and immunity testing. These antennas are constructed using light weight aluminum with a corrosion resistant conductive coating for indoor or outdoor use. Each antenna is individually calibrated. The calibration data and certificate will be shipped with each antenna.The high gain reduces input power requirements to generate high electromagnetic field levels for immunity testing. High gain also increases antenna sensitivity to low level signals.

Inductive Sensors
Inductive Proximity Switches, self contained, depend on the output of an oscillator for their operation. The oscillator resonant circuit uses an open core coil to produce a concentrated high frequency electromagnetic (RF) field, which emerges from the active surface of the sensor. If a metal target (or other electrically conductive material) enters this field, eddy currents will be induced in it, causing the resonating oscillator to be damped.

Antenna, Loop Sensor
EM-6873 | 20 Hz – 100 KHz
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.

Gauss Meters
A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both. Thus, it is important to review the specifications of a gauss meter prior to purchase to ensure suitability for the intended application.Neodymium (NdFeB) permanent magnets are among the world's strongest and most widely used magnets. When testing magnets made of neodymium or other rare-earth elements, a gaussmeter or magnetometer capable of measuring DC magnetic fields is required. However, most electromagnetic fields encountered are generated by AC currents. Examples include electrical power lines, transformers and wiring for overhead lighting, solar panels and other electrical devices and equipment. Electromagnetic fields from electrical installations are believed to cause feelings of nervousness, anxiety and paranoia in EMF-sensitive human beings.Most gaussmeters offered by PCE Instruments can be calibrated and certified according to DIN ISO 9000 standards for an additional fee. Replacement gaussmeter probes and optional accessories are available for most gaussmeter models.

RF Test
RF is short for radio frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum.
