907023/334 for High Pressure and
Vacuum Applications
The 907023/334 probe is for the dewpoint measurements in
pressurized rooms and industrial processes. The probe is provided
with a nut, a fitting screw and a sealing washer. Keep the fitting screw
and the nut in place on the body of the probe during handling to
prevent damage to the highly polished surface of the probe. Follow the
instructions below to achieve a leak-tight assembly:
1.
Remove the fitting screw from the nut and the probe.
2.
Attach the fitting screw to the chamber wall with a sealing
washer. Tighten the fitting screw into the threaded sleeve with a
torque spanner. The tightening torque is 150 ± 10 Nm (110 ± 7
ft-lbs).
3.
Insert the body of the probe into the fitting screw and attach the
nut manually to the fitting screw so that the connection feels
tight.
4.
Mark both the fitting screw and the nut hex.
