Specifications - General Tubehead
The following outlines the general operating specifications of
the Tubehead Assembly.
❏
Physical Specifications _____ Water Cooled: 8.5" dia. x 26.5"
length - 32lbs (approx); Air
Cooled: 8.5" dia. x 29" length -
36 lbs (approx)
❏
Anode Cooling System _____ Recirculating Liquid Cooling unit
or Fan Forced Air
❏
Radiation Output __________ 20R/minute @200kV, 4.5mA @
50cm through 0.5 in. of
Aluminum
❏
Leakage Radiation _________ 0.8 R / hr
❏
Tube Pressure Sense _______ Monitors pressure of the SF6 gas
within the Tubehead. Shuts unit
down if pressure falls below 25
psi.
❏
Anode Thermal Sense ______ Monitors temperature of the X-ray
Tube Anode. Shuts down unit if
Anode temperature rises above
220
°
F.
❏
Pressure Relief Valve _______ Automatically releases SF6 gas
from Tubehead if pressure rises
between 75 - 80 psi.
❏
Pressure Gauge ___________ Displays SF6 gas pressure within
Tubehead. Used in conjunction
with Temperature Compensation
chart to visually inspect Tubehead
pressure.
