Monitoring High Frequency EMF Radiation in Plastics Production
During the production of some plastics, inductive heating using a high-magnetic-field pulse initiates a chemical reaction to generate composite materials.
There are various induction systems used in plastics manufacturing, ranging from 20Khz to 50Mhz or higher.
These should be assessed for EMF safety as they can be operating at high power, sometimes 5 to 10KW or more.
This would certainly present an EMF safety hazard to nearby workers.
Electromagnetic Fields (EMFs) are classed as non-ionising radiation. Unlike ionising radiation, such as X-Rays and Gamma rays, non-ionising radiation does not damage DNA. However, exposure to higher frequencies can cause the temperature in body tissues to rise, which may lead to health complications.
ARPANSA, the Australian Radiation Protection and Nuclear Safety Agency has published a Standard for Limiting Exposure to Radiofrequency Fields – 100 kHz to 300 GHz. This is applicable to workplaces, where there is a risk of staff being exposed to EMF radiation.
Equipment for Monitoring High Frequency EMF Radiation in Plastics Production
The Wavecontrol SMP3 EMF meter is a professional tool designed to measure electromagnetic fields (EMF) over a broad spectrum of frequencies. In the plastics industry, this device is employed to monitor and ensure the safety of workers who may be exposed to EMF produced by different equipment and processes. In the plastic industry the EMF is generated by various devices such as motors, heaters, welders, and control systems.
Extrusion and Injection Molding Machines: The electric motors and heaters in these machines generate EMF as they melt and shape plastic.
Ultrasonic Welders and Heat Sealers: Ultrasonic welding machines used to join plastic parts emit EMF due to the high-frequency electrical currents used to generate ultrasonic waves for welding.
Conveyors and Handling Systems: Conveyor belts used to transport plastic materials or products in the production line are driven by electric motors, which generate EMF during operation.
Based on the frequency the WP10M probe would be most suitable for this application. With the WP10M probe you can carry out analysis using both the FFT method and the Weighed Peak Method (WPM). The WP10M probe can measure both E & H fields up to 10 MHz. It complies with ARPANSA standards as well as ICNIRP, SC6, EMFV, IEEE, and EU standards.
