4 Mounting

4.1 General instructions

Make sure that all parts of the instrument exposed to the process, in

particular the sensor element, process seal and process ﬁtting, are

suitable for the existing process conditions. These include above all

the process pressure, process temperature as well as the chemical

properties of the medium.

You can ﬁnd the speciﬁcations in chapter "Technical data" or on the

type label.

Select an installation position you can easily reach for mounting and

connecting as well as later retroﬁtting of an indicating and adjustment

module. The housing can be rotated by 330° without the use of any

tools. You can also install the indicating and adjustment module in four

diﬀerent positions (each displaced by 90°).

Use the recommended cables (see chapter "Connecting to power

supply") and tighten the cable gland.

You can give your DPT10 additional protection against moisture

penetration by leading the connection cable downward in front of the

cable entry. Rain and condensation water can thus drain oﬀ. This

applies mainly to outdoor mounting as well as installation in areas

where high humidity is expected (e.g. through cleaning processes) or

on cooled or heated vessels.

The ventilation for the electronics housing is realised via a ﬁlter

element in the vicinity of the cable glands.

Information:

Make sure that the ﬁlter element is always free of buildup during

operation. A high-pressure cleaner must not be used for cleaning.
