The RadMan 2LT and RadMan 2XT Radiation Monitors are warning devices for the protection of people who work in areas where increased levels of electromagnetic radiation are present. Broadcasting, telecommunications and radar antennas are sources of strong electromagnetic fields. The device is worn on the body and warns its user in good time before the permitted limit values are exceeded.


Display and warning signals

The actual field exposure level is indicated in six steps from 5% to 200% by LEDs. The percentages refer to the proportion of the power density limit value specified in a safety standard. If the field exposure level exceeds 50% of the limit value, the device vibrates and emits a loud alarm tone. There is also a bright light in the top part of the RadMan 2 that can be easily seen from various angles. The light flashes red in time with the alarm signal. A second, more persistent alarm sounds when the 100% threshold is exceeded, warning the user to leave the danger area.


Standard compliance by means of shaped frequency response
.

The permitted limit values specified in the standards vary according to the frequency. Weighting filters in the sensors of the RadMan 2 simulate the frequency response of the standard. They ensure that the alarm thresholds are correct over the entire frequency range. Settings are not necessary.

Minimal body effect

Personal monitors are generally worn on the person. RadMan 2 is supplied fitted with a suitable attachment and RF absorber that allows it to be fixed easily to a harness or belt. The RF absorber reduces the signal reflections caused by the body which would otherwise affect the result displayed by the monitor. If needed, the RadMan 2 can be released from the attachment with one hand in order to determine the field exposure away from the body with an isotropic directional characteristic.
