The new RadMan 2 - simply activate to work safely in electromagnetic fields
(PresseBox) - Anyone who has to work with high intensity electromagnetic fields (EMF) must have maximum protection at all times. This primarily applies to working in the near field region of radar antennas, broadcast transmitters, or cellular base stations as well as close to industrial equipment that uses high frequency energy for smelting or welding. Personal safety equipment (PSE) that gives a 100% reliable warning when critical EMF values are reached is essential to exclude health risks in such situations. Narda Safety Test Solutions has now developed the RadMan 2 for this complex monitoring task, with future 5G applications also in view. This small, handy device that is worn on the body gives insistent, timely and above all reliable warning of impermissibly high levels of exposure to electromagnetic radiation like no other device of its type.
The new radiation monitor perfectly combines clever innovation and the decades of experience gained by the market leader with the tried and tested technology of its predecessor, which also has the distinction of being the world?s best-selling personal monitor. This unique blend of features redefines the current and future standards of EMF safety. It is now easier than ever to activate and use the device, particularly for operatives who are not generally designated experts in measurement technology. For example, the automatic sensor test is a new feature that checks that the sensors are functioning correctly as soon as the device is switched on. This test has been realized in the RadMan 2 for the first time in any personal monitor, to provide maximum safety. The external test generator usually needed for such a test is no longer required. The charge status of the batteries is also checked and displayed when the device is switched on. RadMan 2 can operate for 800 hours from fully charged batteries. The person requiring protection does not have to do anything other than switch the device on, leaving them free to concentrate on their job.
Highest frequency coverage
There are two versions of the RadMan 2 available: the less expensive LT model for up to 8 GHz, with reduced features and fewer functions, but with the same premium protection level typical of Narda devices as its ?bigger brother?, the XT, with its range of up to 60 GHz. With what is currently the highest frequency coverage on the market, it is capable of providing sure, reliable warning of radio and radar frequency fields as well as of 5G millimeter waves.
RF absorber for greater precision
Following in the footsteps of the original, highly successful RadMan, the RadMan 2 has now appeared as a worthy successor after more than 20 years. It has inherited only the best features of the original. For example: only the special RF absorber ensures that the device can measure electromagnetic fields when worn on the person without affecting the accuracy of the result. The signal reflections caused by the body would otherwise impact on the displayed result, negatively affecting safety. The absorber material for the new device is a permanent part of the special holder for the climbing harness and belt, so that when the device is used correctly it is automatically always where it belongs, between the body and the sensor, even when the device is unhooked.
E field and H field sensors
The personal monitor is equipped with both E field (electric) and H field (magnetic) sensors for applications in the near field and far field regions of TV and radio antennas. In contrast with conditions in the far field, the electric and magnetic fields in the near field are independent of each other. This means that it is possible for the person requiring protection to move through regions in the near field where there is a strong magnetic field and a very weak electric field or vice versa. Users of the RadMan 2 do not need to know which field region they are in, or to have to set the device up accordingly. It automatically gives a correct warning, regardless of the field type and the distance from the source. If the worst comes to the worst, the higher value of the two fields will trigger the alarm.
The personal monitor is easily released from the special holder using just one hand. Once released, the device measures the field isotropically, i.e. non-directionally. This ensures that all hotspots in both the E field and the H field are reliably displayed regardless of the direction in which the device is pointing. This practically eliminates erroneous assessment of the field, as the device basically does not have a blind spot.
XT special features: Tone search function and Pulse Mode
The XT version allows operatives to make a precise search for leaks at arm?s length (imagehly advantageous feature of the XT version (image 2) is its ?Pulse? mode, which enables reliable detection of brief, pulsed signals. The alarm responds much faster in this setting. This function is needed, for example, when the measurement technician is working close to a rotating radar antenna and is therefore periodically only briefly illuminated by the radiation.
Automatic compliance with standards
The correct values specified in the relevant standard are automatically used as the basis each time that the RadMan 2 sounds the alarm. The actual exposure as a percentage of the applicable upper limit according to ICNIRP, the 2013/35/EU Directive, FCC or Safety Code 6 triggers the alarm. The device takes account of the fact that the permitted limit values specified in each standard are frequency dependent, which means that the alarm thresholds vary accordingly. Users therefore do not need to set the current limit value or even work out the situation from the displayed values. The RadMan does all of the work, using its patented shaped frequency response function to determine the correct alarm thresholds automatically.
All the results determined from each assignment can be fully documented. The internal data recorder continuously records all the measured exposure values for the E field and the H field for evaluation or further processing using a PC.
The safety of Narda?s new personal monitor is further enhanced by the fact that it automatically tests itself completely, and it is also optimally designed for use in tough workplace environments. Its robust casing is hermetically sealed, ensuring outdoor capability, and is IP-65 rated to give effective protection from dust and moisture.
Display and warning signals
The alarm of the new test and warning device is now even more insistent and noticeable. Whenever the limit value is exceeded under any imaginable conditions of use, the person working in the field is warned by an alarm that is louder and brighter, and which even vibrates. Even if the monitor is worn on the chest, the new, large red alarm indicator is clearly visible from above and commands attention. Six LEDs on the front of the device indicate how close the actual field exposure level is to the limit in steps ranging from 5 to 200%. A loud alarm signal sounds if 50% is exceeded, and the device also flashes and vibrates. The visual and audible alarms become even more intense for the second alarm level from 100% and above, as the personal monitor makes it quite clear that the wearer needs to leave the danger area immediately. The use of different alarm signals ? optical, audible, and mechanical ? ensures that any warning cannot be missed. This is in stark contrast to devices that merely use a vibrating alarm, which can easily be absorbed by thick layers of clothing when working outdoors.
Summary
Cellular networks are set to expand greatly with the upcoming 5G mobile communications standard. This can utilize higher frequencies compared to the older technologies, but it results in a reduction in range. With the RadMan 2, the EMF and occupational safety experts at Narda STS have succeeded in making an established icon of occupational safety in electromagnetic fields even better than before, with proven simultaneous monitoring of E fields and H fields according to an ICNIRP compliant shaped frequency response, a unique automatic sensor test when the device is activated, and an alarm LED that is clearly visible from a distance. Or, by extending the frequency range up to 60able to everyone, at least when the field exposure level approaches the internationally standardized limit values. It systematically excludes sources of errors such as reflections, damage to the device, or incorrect operation, to ensure the maximum degree of safety for all work in critical electromagnetic fields.
