6.7 Cleaning gauges

This cleaning/degreasing process is only suitable for use with pressure gauges with

either phosphor bronze, beryllium copper, Monel or stainless steel Bourdon tubes in the

form of a "C".

It is not advisable to degrease pressure gauges with steel Bourdon tubes since a very

small amount of corrosion on the bore of a Bourdon tube can cause inaccuracies of

reading and early failure of the tube.

Wear safety goggles!

Protect eyes from ying particles and liquid splashes.

This method of cleaning is not suitable for use with pressure gauges which are tted

with coiled Bourdon tubes, nor any gauges which are to be used on oxygen, as

complete removal of oil is not assured. Please contact DH-Budenberg/WIKA.

Equipment

This consists of a syringe and a special needle with the point bent through 90°.

Instructions

1. Fill syringe with solvent (suitable cold degreasing liquid).

2. With gauge connection pointing upwards put needle into connection and insert by

feel the point into the hole leading to the tube.

3. Inject the solvent. Ideally the tube should be half full.

4. Shake gauge in various attitudes to agitate solvent.

5. Suck solvent back into syringe, holding gauge at an angle.

6. Check that solvent removed is clean. To be sure that all oil has been removed,

repeat cleaning process until solvent removed from gauge is as clean as that put in.
