FieldSENSE protects workers against RF overexposure
IT WORKS AS HARD AS YOU
The only RF monitor you will ever need
Coverage: 50 MHz to 60 GHz
The fieldSENSE, now in its 3rd generation, has a proven track record of ensuring on-site employee safety. The fieldSENSE is specifically designed with the RF climber in mind – whether working in the nearfield of a broadcast system or in the far-field of a 5G system, exposure is correctly assessed and a warning is
sounded, should the levels approach and exceed the occupational health & safety limits. The device can be attached to a special harness-attachment mechanism to ensure it cannot be dropped, yet still within hearing range of the buzzer in the event of a warning.
RF Tower Climbers
FieldSENSE devices are designed with the climber in mind. Trusted by 1000s of RF workers world wide.
HVAC & rooftop technicians
Bucket truck workers
Utilities, small cell and street lighting all call for bucket truck access, all potentially placing you in line with transmitting antennas.


fieldSENSE 60
The frequency range has been expanded to 50 MHz – 60 GHz which means the user is covered whether working in the near-field of a broadcast system or in the far-field of a 5G system. This means this is the only RF monitor a worker will need.
RF Safety guidelines use the radiated power density, S in milliWatt/cm2 or Watt/m2 to assess exposure to electromagnetic fields in a given situation. This is derived from the measured E (electric) and H (magnetic) fields. To accurately assess a given exposure situation, both of these should be measured, especially when working very low in frequency around FM transmitters for instance. Only measuring E field in these instances can lead to inadvertent RF overexposure. The extended frequency range correctly measures the H field as it is required when measuring lower in frequency.
The exposure limits, such as the FCC (NCRP), SC6 or ICNIRP limits are all shaped over frequency and as such PPE must also have a shaped probe response to accurately measure in accordance with it. RF monitors not having a shaped response are inaccurate and can result in an individual being overexposed.
High brightness amber LED indicators for direct sunlight visibility and a loud buzzer ensure the user won’t miss a thing. It is specifically designed to be operated whilst wearing gloves to help prevent losing a glove down a tower.
The device uses readily available AAA (LR03) batteries.


fieldSENSE 2.0
The FieldSENSE 2.0 has a total of 6 orthogonal E & H field probes to ensure that the combination of all sources of radiation from all angles are correctly measured and assessed in accordance with the safety limits.
The device has an advanced E and H field data logger which records all user measurements so that they can be easily accessed over a USB connection to a PC in the office. Additionally, the data can be viewed in real-time over the USB connection with the PC application.

The fieldSENSE 2.0 has a co-moulded enclosure with a base layer of polycarbonate which is typically used in riot shields, and an outer elastomer layer made of TPU which is designed for hard wearing environments. The design provides for IP64 dust & moisture ingress rating.
