FS8000 fieldSENSE Public RF Safety Monitor

The fieldSENSE Public introduces a cost-effective solution designed specifically to protect non-RF workers from accidental RF overexposure.  Property owners hosting BTS sites can now ensure that contractors like window washers, painters, and maintenance staff remain in a safe RF environment.

Here's a quick feature summary:

• Compact, durable design intended for everyday use
• Affordable & competitively priced
• Indicates RF field strength using bright LED's
• Very simple single button operation: no RF knowledge necessary
• Loud alarm will warn in case of EMF overexposure danger.
• Uncomplicated, robust and reliable.
• Calibrated to ICNIRP General public reference levels.

Using the fieldSENSE Public Monitor

"Measure mode"
When aproaching a base station site, the worker may use fieldSENSE Public in "measure" mode to ensure that he/she is not overexposed.

In "Measure" mode the field strength is measured continuously. A level indicator bar provides visual feedback of the exposure levels as the instrument is moved around.

The user can pinpoint sources of RF radiation and confirm that specific base station sectors have been shut down, or are transmitting reduced power levels so that can it be considered safe to approach and complete a required task.

"Monitor mode"
After confirming that relevant sectors have been powered down, fieldSENSE Occupational can be switched to 'monitor' mode and mounted in a suitable position and orientation.

FieldSENSE continuously monitors the RF radiation levels and will alert the worker in the case of significant exposure changes. The worker is alerted by both an audio alarm and a visual alarm on the level indicator bar.

Technical information

International Exposure Limits
The unit is calibrated to the FCC (NCRP) Public reference levels.

Frequency bands
The operational frequency range monitors and measures all bands commonly used for mobile telecommunications.  380MHz to 2.7 GHz .

Omni-directional, linear polarization
The fieldSENSE device should be held upright when being used to locate sources of EMF radiation. This will ensure that the omnidirectional, vertically polarized field probe will provide the user with a conservative measurement of the exposure at that position, also for cross-polarized BTS antennas. In monitor mode, the fieldSENSE should also mounted vertically to ensure correct operation.

User interface and operation

A single button toggles between user modes and power-on/off. The display and processing of measured data is limited to that which is required to make informed on-site decisions and take the necessary precautions.

The device features a durable design intended for everyday use, and is compact enough to fit easily into the pocket of the user. The rubbery outer sleeve offers improved grip and protects the fieldSENSE against mechanical shock and impact.

A lanyard can be used to secure the fieldSENSE around the wrist of the user and thus minimize the risk of dropping the device. A standard tripod socket at the bottom can be used to mount the fieldSENSE on a tripod when used in monitor mode.
