EMF Electromagnetic Field Surveys: EMI / EMC Testing & Consulting: Dallas, Houston, Austin, USA
ScanTech has performed thousands of EMF Surveys and consulting over the past 20 years for a variety of commercial / industrial clients and concerns including potential EMI (Electromagnetic Interference) issues with biomedical implants, equipment and other control infrastructure.
What is an EMF Survey / Electromagnetic Field Testing?
It is a detailed survey of the electromagnetic sources and EMF fields of potential influence in a given room, building or other area of interest. The purpose of an electric, magnetic, and electromagnetic field (EMF) survey is to assess exposures to time-varying electromagnetic fields, static electric fields, and static magnetic fields, such as those produced by industrial motors, MRIs, high voltage power lines, or broadcast antennas. The EMF exposure concern may be to employees, a specific employee with a biomedical implant, or sensitive scientific / industrial equipment.
Depending on the needs of the client, the following fields are measured:
AC 60 Hz Magnetic Fields: Magnetic fields generated by CURRENT running through the main electrical wiring in the building / facility and / or from concentrated point sources.
AC 60 Hz Electric Fields: Electric fields generated by VOLTAGE running through the main electrical wiring in the building or facility.
DC Magnetic Fields: There is always a DC magnetic field from the Earth that is typically 550 milliGauss (mG) but other equipment and the shaping of the geomagnetic field can alter the field density; even lower it in some cases.
Quasi-DC Fields: These are DC magnetic fields with time varying intensities, such as a DC motor under different loads.
RF / Microwave Radiation Fields: Radio frequency fields from wireless equipment and in some cases generated by arcing, welding activities, etc.
Anomalous readings and EMF field intensity levels of concern are noted, documented and investigated. Professional consultation is provided onsite and a written report given.
