Type of Sensor
(crystals sold separately)
Standard Cool Drawer Dual sensor
(water lines parallel to crystal face)
with shutter
Right angle Cool Drawer Dual sensor
(water lines perpendicular to
crystal face) with shutter
Length of Sensor – SEE NOTE 3
Length – 10.2 to 66 cm (4 to 26 in.)
SEE NOTE 4
Feedthrough Connection
Sensor welded to feedthrough –
Feedthrough equipped with
Ultra-Torr
® compression fittings
(allows for adjustable sensor
length). Not available with CF40
feedthrough.
Feedthrough –
SEE NOTES 2 and 5
1 in. bolt
CF40 (two piece)
NOTE 1:
Orders for a WELDED sensor/feedthrough combination cannot
be accepted without a completed sensor length specification
form (provided by INFICON). Once a welded sensor order is
confirmed, it cannot be canceled.
Note 2:
Feedthrough configuration varies depending on options selected
(type of feedthrough, and connection). Example: CDD-AF47
and -BF47 use a two-piece hybrid feedthrough design due to
dimensional limits of a standard CF40.
Note 3:
Sensor lengths are measured from center of the crystal
closest to the end of the sensor to the vacuum side (sealing
surface) of the feedthrough (see length specification form).
Note 4:
For sensors ordered without a weld connection (option “8”),
tubes are made to a length of approximately 76.2 cm (30 in.)
for standard sensors and approximately 66 cm (26 in.) for
right angle sensors.
Note 5:
Cool Drawer sensors are not available without a feedthrough.
