Safe Radio Technology
MR measurement relies on non-ionizing, radiofrequency electromagnetic radiation similar to the frequency band used for aerial TV or radio. This radiofrequency field is transmitted and received by an antenna in the MRA sensor core.
Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. Taken together, all forms of electromagnetic energy are referred to as the electromagnetic “spectrum.” Radio waves and microwaves emitted by transmitting antennas are one form of electromagnetic energy.
Further safety information on RF radiation can be found on the US FCC website here.
The MRA uses integrated shielding and electrical interlocking switch systems to adhere to the strictest RF and electrical safety standards for use on mine sites in close proximity of personnel.
