Model # FML-7B

FEATURES:

ON-LINE REAL-TIME MONITORING

ALL PLUG-IN MODULAR

RACK MOUNTING OR CASE

SINGLE OR MULTI-CHANNEL

RUGGED GM DETECTORS

LOCAL OR REMOTE MONITORING
(UP TO 500 FT. CABLE OPTIONAL)

HIGH LEVEL ALARM, SOLID STATE, NON-CONTACTING

RS-232 OUTPUT FOR PRINTER OR PC AND REMOTE DISPLAY OUTPUTS

MICROPROCESSOR BASED DATA MEASUREMENT AND DISPLAY

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

GENERAL DESCRIPTION: The FML-7B Series Radiation Monitors incorporate a digital alarm ratemeter, power supply, alarm, amplifier, choice of rack or case, and reliable GM detector. Because of the plug-in modular construction, additional channels or functions can be added. GM detectors 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. Optional stand-by battery power available.

WIDE RANGE BETA-GAMMA GM

AREA MONITOR

Model # FML-7B

SPECIFICATIONS:

Range: 4 decade dynamic range 0.1 mR/hr to 1 R/hr * (artificial background supplied by internal radiation source in probe)
*Other ranges available to 1,000 R/hr or down to 0.01 mR/hr.
Accuracy: +/- 10% of decade
Detector: Energy compensated halogen quenched GM detectors, in ruggedized probe with internal radiation source. Supplied with 8ft. cable. (Up to 500ft. of cable can be supplied as an Option.)
Optional high range systems use High Range GM detectors. Detector is supplied with 8 ft. cable (up to 500 ft. of cable can be supplied as an option).
Anti-Saturation: Circuity is incorporated to prevent readings from falling below full scale in over range conditions (tested to 1,000 R/hr).
High Voltage Output: 0 to +1500V at 200 µ A continuously adjustable.
Energy Dependence: µ20% from 100 KeV to 1.2 MeV.
Temperature: Operating range between -30^oC and 50^oC; drift less than 17% per ^oC at room temperature. 0-95% humidity non-condensing.
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-7 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.
