Maintenance Intervals

SensoGate® WA 130 H

The following maintenance intervals are generally recommended:

Maintenance interval*

Operations required

First inspection after

a few weeks

Move the probe to the SERVICE position and observe

the outlet. If the retractable fitting is untight, process

fluid will leak from the outlet hose.

Observe the leakage holes (holes directly beneath the

coupling nut, see “Build-up of the Retractable Fitting”

on Page 34). When there are deposits on these leak-

age holes or compressed air is escaping, there may

be leakages in calibration chamber or the pneumatic

system.

After 6 – 12 months

(after successful first inspection and

suitability of all materials used, this

time period may be extended.)

Repeat the measures of the first inspection. When

there are deposits on the leakage holes or com-

pressed air is escaping, replace the process-wetted

(dynamically stressed) gaskets.

After 10,000 – 20,000 probe travels

You should replace the process-wetted (dynamically

stressed) gaskets.

After approx. 2 years

Particularly if you use chemically aggressive cleaning

agents, you should check the rinse-wetted gaskets

and replace them if required.

After approx. 5 years

Servicing the pneumatic drive unit and relubricating

the gaskets.

*) These maintenance intervals are rough recommendations. The actual intervals depend on the

application of the retractable fitting.

As a result of highly variable process conditions (pressure, temperature, chemically aggressive

media etc.), general information on necessary maintenance intervals is difficult to provide. If

proven experience from similar points of measurement with regard to materials used and their

resistance unter process conditions is available, the maintenance intervals can be adjusted by the

customer. If previous experience is positive, parts of the first inspection may be omitted.
