Ludum 3500 Series Gate Monitor
Source: Suntrac Services, Inc
Indicated Use: Low level gamma radiation monitoring
Indicated Use: Low level gamma radiation monitoring
System Operation: The system will continuously monitor background levels until the infrared sensor identifies an object. It will then automatically switch to checking the object for radiation caused by contamination until the object is clear of the sensor at which time the system will return to monitoring background.
Detectors: These systems utilizes multiple plastic detectors of various sizes (see table below)
Audio: Unimorph type speaker (greater than 68 dB at 2 feet)
Meter: 2.5" (6.4 cm) arc, 1 mA analog type
Meter Dial: 0 - 25 kcps
Checking (green LED): Indicates vehicle is passing through the system
System OK (green LED): Indicates the system is functioning properly
Channel 1: Pushbutton to check the count rate on channel 1
Channel 2: Pushbutton to check the count rate on channel 2
Alarm: Indicated by a red LED's, red flashing lamp, and audible tone (Can be internally set from 1 - 8.5 deviations above background in half step increments )
Audio Acknowledge: Push-button to silence the audio after an alarm has been indicated
Alarm Reset: Push-button to reset the alarm
Fail 1 (yellow LED): Indicates when a signal is not received from detector 1
Fail 2 (yellow LED): Indicates when a signal is not received from detector 2
