Front Load Single and Dual Sensors Operating Manual

4 Form, measure, and mark the sensor tubes (see section 2.3.1 on page 2-10).

NOTE: Use the Tube Bender Kit, PN 750-037-G1, provided with all

non-welded sensors, to form the tubes.

CAUTION

Do not form the sensor tubes with a bend radius

less than 8 mm (0.315 in.) from the inside of the bend or

9.5 mm (0.375 in.) from the center line of the tubes.

Bends must be farther than 20 mm (0.79 in.) away from

the braze joints on the tubes.

Do not use the sensor body as a leverage point. This may

result in a failure of the braze joints on the tubes.

5 Build the sensor/feedthrough assembly.

6 Remove the sensor and the feedthrough.

7 Cut the water cooling tubes and air tubes to the proper length. Verify that they

are clear of metal particles by blowing compressed air through the tubing.

8 Connect the water cooling tubes and air tubes directly to the feedthrough,

or use vacuum rated couplings.

 Vacuum rated connectors, such as Swagelok® VCR® or VCO®, are

recommended for use between the sensor and the feedthrough to speed

maintenance. If brazing adapters are to be used, attach them to the sensor

water-cooling tubes prior to connection to the feedthrough. Make

connections as follows:

CAUTION

To prevent damage to the feedthrough or sensor

during brazing, ensure that at least 2.54 cm (1 in.) of

water tube remains between the sensor and the flame.

 Clean the water tube and adapter surfaces with solvent, if necessary.

 Apply brazing flux to surfaces being joined.

 Braze the connections using a flame temperature appropriate for

the brazing material being used.
