APPLICATION: Area monitor in and around nuclear reactors, hot cells, irradiators and other facilities handling radioactive materials or X-rays.

GENERAL DESCRIPTION: The FIL-7 Series Radiation Monitors incorporate a digital alarm ratemeter, power supply, alarm, electrometer and reliable ion chamber. Because of the plug-in modular construction, additional channels or functions can be added. Ion Chamber and circuit design prevent the system readings from falling even in very high fields. Front panel controls allow the alarm set point to be displayed. Alarm activation produces flashing red light on front panel and piercing intermittent 2000Hz tone. Optional relay is also closed (or opened) for activation of remote alarms. Stand-by battery power is optional Rack or case is supplied.

SPECIFICATIONS:

Range: FIL-7DP:
0.1 - 10,000 mR/h (5 decades) is standard.
Optional range systems offer any 3 or 5 consecutive decades from 0.1 mR/h to 10⁶ R/h.
Accuracy: ±10% of decade
Detector: Air equivalent ion chamber. Standard systems use Model IC-2 (for gamma) or Model IC-1 (for beta-gamma). Both models have graphite lined phenolic walls and an active free air volume of 2 liters.
Optional high range systems use smaller chambers. Detector is supplied with 8 ft. cable (up to 500 ft. of cable can be supplied as an option).
Detector Response:
Gamma Energy: IC-1 is sensitive down to 2 KeV; energy independent (±15%) 4 KeV to 6 MeV. IC-2 is sensitive down to 10 KeV; energy independent (±0 KeV to 7 MeV.
Beta Energy: Sensitive down to 0.15 MeV; energy independent (±25%) 0.4 MeV to 7 MeV (IC-1 only).
Temperature: Operating range between -30°C and 65°C; drift less than -0.4% per °C at room temperature. 0-95% humidity non-condensing.
Data Processing:
High resolution charge to pulse electronics - Analog to Digital.
Accurate internal timer.
Readout: Large, easy to read Roentgen or Sievert display. User programmable.
Front Panel Controls: Alarm Level Set, Display Alarm Set Point, Alarm Reset Pushbutton Power On-Off, Switch
Alarms: Alarm level is adjustable over entire range. Alarm indicators include flashing red light and beeper.
Power: 105-125 V (or 200-240 V), 50-60 Hz. Optional 12 Volt operation. Optional standby batteries, normally under continuous charge, automatically provide power for one week in event of AC power failure.
Mounting: Electronics are normally furnished in FM-5 case but can be furnished uncased with mounting bars for rack or Nema 4 (hostile environment) cabinet.
Options:
;Multiple channel systems.
Solenoid activated check source for system calibration.
Remote alarm-flasher-howler
Remote meter readout with alarm.
Analog output for chart recorder - model FIL-7DPA
Standby batteries.
Cable to 500 feet.
