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

Rooftop hosted base stations place those working there at risk of RF over-exposure. FieldSENSE has you covered.

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

Frequency range

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. 

Isotropic
The fieldSENSE60 has a total of six orthogonal E and 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.
E & H fields measured

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.

Data logging
The fieldSENSE60 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.
Voice notes
The inbuilt logging feature allows for quick voice note taking, which can be accessed later in the office, the data is paired with the logged E and H fields so specific exposure conditions can easily be tagged.
Shaped response

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.

Fall-detect & alarm
The device has an inbuilt fall detection system which sounds an alarm should the user accidentally fall. The alarm is easily silenced should the climber still be conscious but, should they have been knocked unconscious the sounding alarm will attract the attention of colleagues to immediately initiate rescue actions thus reducing the potential effects of suspension trauma.
User interface

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.

Harness fastening
The fieldSENSE60 harness attachment mechanism has been completely redesigned to include a coiled lanyard system. This facilitates the smooth handling of the device during operations while still remaining visible and audible. Should the device be dropped there is no risk of it falling off the site.
Wrist strap
Easily adjustable wrist strap ensures no accidental dropping of the device when working at heights.
AAA batteries

The device uses readily available AAA (LR03) batteries.

“Grippy” design
The device has a custom bevelled design that fits tightly into the user’s hand with a textured soft elastomer surface and grip ridges ensuring no fumble moments up in the air.
Rugged IP64 enclosure
The fieldSENSE60 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.
Zipper case with moulded foam insert
Shipped in a heavy-duty zipper case with a custom moulded insert makes for even further protection of the device.
Tripod attachment point
A tripod attachment point on the base of the device allows for setting up remote monitoring of a site, or for attaching an extension pole in given instances.

fieldSENSE 2.0

Frequency range
The frequency range has been expanded to 50 MHz – 6 GHz which covers all typical television and FM radio broadcast services and most mobile telecommunications services including low and mid-band 5G, amongst others.
Isotropic

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.

Harness fastening
The strap and buckle system for fastening the device to a climber’s harness ensures easy access to it. It has been specifically designed to keep it away from areas which are either heavily utilised for carrying lots of gear or tools, like the waist, or areas which impede easy climbing or limit circulation like the arm or wrist.
Wrist strap
The easily adjustable wrist strap ensures that users never accidentally drop the device when working at heights.
AAA batteries

The device uses readily available AAA (LR03) batteries.
