Electromagnetic Field Exposure 

Model SMP2
 SMP2 intEN
To measure people’s exposure to electromagnetic fields in accordance with ICNIRP, IEC, EN, IEEE, European Directive 2013/35/EU, FCC and other standards.A unique combination of broadband measurement and spectrum analysis in a single device. The only device in its class that offers genuine 2-in-1 performance: broadband electromagnetic field meter (1 Hz to 40 GHz) plus industrial frequency spectrum analysis (1 Hz to 400 kHz). Our SMP2 provides the most advanced features and technology on the market, designed for users who need high-quality measurement, ease of use and good reporting too

Applications 

Telecommunications 

Telecom 1
Mobile telephone systems, radio broadcasters and other communication systems are the main sources of radiation in this area. In most cases measurements are taken under far field conditions and so use of an E (electric) field probe (e.g. the WPF8) will be sufficient. In the case of low frequency transmitters, we might find near field conditions, and so the H (magnetic) field will also have to be measured, e.g. with the WPH30 probe. The applicable reference standards include: IEC 62232 and EN 50492 (base stations), EN 50496, EN 50554 EN 50475 and EN 50476 (broadcast), EN 50400 and EN 50401 (fixed equipment for radio transmission).

Energy  

SMP2 applications Energy
Low frequency electromagnetic fields are associated mainly with the supply of electricity, through the generation, distribution and use of alternating current (AC), and they are always present in our surroundings. Electricity operates at the frequency of 50 Hz or 60 Hz, depending on the country. Electric power stations, high- and medium-voltage lines, transformers, electric motors and railway lines are the main sources of these electromagnetic fields. The applicable reference standards include: IEC/EN 62110 (AC power systems), IEC 61786-1 and IEC 61786-2 (measurement of DC and AC fields from 1 Hz to 100 kHz).

Industry

SMP2 applications Industry
Workers’ exposure to electromagnetic fields must be monitored for their safety in a wide range of industrial areas, machinery and manufacturing processes. Some examples include induction heating, welding systems and processes, radio frequency (RF) heating, tempering and drying equipment, chemical processes (electrolysis), etc. Home appliances also generate electromagnetic fields that must be measured and evaluated before they can be put on the market. The applicable reference standards include: EN 50519 (induction heating), IEC/EN 62822-1, IEC/EN 62822-2 and IEC/EN 62822-3 (welding), IEC 62233 (household appliances), IEC 62493 (lighting), EN 50527 (workers bearing active implantable medical devices), etc.

Electromedicine

SMP2 applications Medical
Magnetic resonance equipment, diathermy and hyperthermia equipment, and electrosurgery equipment are the main sources of electromagnetic radiation in the medical industry. The medical staff using that equipment or working in nearby spaces are exposed more intensely than patients or people who are passing through, and so exposure within the radius of influence of that equipment must be evaluated and controlled. This includes measurements at low and high frequencies using the suitable devices and probes with isotropic response and RMS. The applicable standard is IEC 60601.

Railway

SMP2 applications Railway

Electricity is very important in the rail industry, since it allows trains to move quickly, quietly, comfortably and with little pollution. High-power and low-frequency energy is used for moving trains and radio frequencies (RF) are used for communication. People’s exposure to electromagnetic fields both inside and outside trains, near communication systems and in stations must be controlled. The standard EN 50500 defines procedures for measuring the levels generated in the rail industry in connection with human exposure.

Laboratories

 SMP2 applications Labs
Electric/electronic laboratories normally use radiofrequency equipment and the levels of electromagnetic radiations can therefore be high. This makes it necessary to ensure workers’ safety in connection with exposure to those electromagnetic fields. To ensure that permitted levels of exposure are not exceeded, the ideal devices are broadband meters that can measure total exposure over the working frequency range of the equipment used. The ideal solution is the SMP2 + the WPF probe that is best suited to the frequency range in question. Wavecontrol also produces continuous measurement systems with built-in alarm, based on the MonitEM devices, designed for monitoring exposure in this sort of facility.

Security scanning of articles and people (RFID/EAS)

SMP Applications RFID EAS
Radio frequency identification (RFID) and electronic article surveillance (EAS) systems are commonly used in public spaces, generating complex electric fields. People who work in spaces near those systems are exposed more intensely than people who are passing through them. Most of those systems work in the low frequency range. The reference standards applicable to exposure to RFID/EAS are: EN 50364 and IEC/EN 62369-1.

Defense

Defense

The main sources of electromagnetic radiation in the area of defense are radar stations, satellite equipment, communication equipment, etc. The SMP2 is particularly suitable thanks to its high-speed digital processing that ensures the ability to detect peaks of up to 1 µs. It can also detect isolated very high amplitude peaks thanks to a special self-scaling function that adapts the device’s dynamic margin (amplification) to the necessary levels. In the area of defense we can find electric and magnetic fields of low frequency, from communications equipment working at several kilohertz (kHz) up to gigahertz (GHz). The SMP2 + WP400 + WPF18 combination is ideal in this case because it can cover the 1 Hz – 18 GHz frequency range with just two probes.

 

MonitEM

Continuous measurement of electromagnetic fields
MonitEm 2
A permanent monitoring system that allows on-going scrutiny of the emission levels of any source of electromagnetic radiation (mobile telephone antennas, WiFi, high-voltage power lines, etc.) and verification that they meet the safety standards established by the competent authorities and regulations in each country. The measurements taken can be published via the Internet to the different stakeholder communities.
