Field Sensor

The field sensor RFS-3G is especially designed for applications in the environment of electron accelerators with a frequency of 3 GHz. The module offers a wide dynamic range of typically 45 dB. RFS-3G is used to detect illegitimate field strengths in order to guarantee personal protection. Due to the integrated monopole antenna, an isolated current loop interface and the compact module design, RFS-3G can be easily integrated into existing systems.


Integrated Monopole Antenna

This compact module features an integrated monopole antenna. Thus, no additional equipment is needed.

Suppression of Unwanted Signals

Unwanted adjacent signals like GSM or DECT are effectively suppressed. This way, the field sensor is not influenced by devices like mobile phones. Wi-Fi 802.11 is suppressed by an internal filter, too.

Analogue Current Loop Interface

The field strength information is provided via an isolated 4 … 20 mA current loop which corresponds to a common industry standard. An easy reduction of the data is enabled. Also the current loop of RFS-3G features an optical indication.


RFS-3G is especially designed for personal protection in electron accelerators in the 3GHz range. For electron accelerators in the 1.3 GHz range, RFS-1G3 is offered.
As RFS-3G is a module especially suited for a certain application, Becker Nachrichtentechnik is able to offer more solutions tailored to individual customer needs.
