- The Hawk EMS is a wall or tripod-mounted radiation monitoring and alarm system designed for use with the Hawk® Radius dual sensor radiation probe. Each EMS System comes with a Hawk Radius Probe. The system is extremely energy efficient and can run for weeks on an internal 9 volt back-up battery if power fails. It is well suited for operating on a small solar panel, which is an optional accessory. The Hawk® EMS features two displays that show the radiation levels measured by each of the probe’s two detectors: the weatherized “pancake-style” Geiger-Mueller tube — which measures alpha (if configured for it), beta, low energy gamma, and x-radiation — and the energy-compensated gamma tube which measures penetrating gamma dose rate. The probe can be mounted next to the EMS system or outdoors, or in adjacent rooms on cables up to 100 ft in length. Standard cable is 3 meters in length. Optional signal booster can support cable lengths longer than 100 feet. Optionally the system can also be configured to share data on ethernet or wireless networks.
- Displays: Two 4-digit liquid crystal displays including mode indicators, one indicates Counts Per Minute (CPM) from the (alpha) / beta / gamma / X-ray detector, the other indicates mR/hr from the energy compensated gamma /x-ray detector
- Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases, as fast as 3 seconds at high rates.
- Accuracy: ± 15% up to 50 mR/hr; ± 20% up to 100 mR/hr
- Anti-Saturation: Readout holds at full scale in fields up to 100 times the maximum reading
- Enclosure: Water resistant housing, tamper resistant with access panel for controls, optional tamper resistant fasteners (IP51 protection class)
- Power: AC wall-mount adapter standard, with battery backup. Greater than 1000 hours battery life with Lithium 9v battery. Low battery indicator.
- Grounding: Earth ground connection point provided for internal lightning suppression, all system signals relative to this ground point.
- Outputs: Detector pulses are available for external data logging or analysis. Alert indicator provides 12V output to activate relay for controlling external power devices, relay is optional. Can be used to activate security devices or cameras, close air intake or water valves, lock doors, and perform other functions.
