4.1 General instructions

Make sure that

the wetted parts of VEGABAR 75, especially

the seal and process ﬁtting, are suitable for the existing

process conditions such as pressure, temperature etc. as well

as the chemical properties of the medium.

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

the "Supplement".

Caution:

After removal of the diaphragm protective cover, the dia-

phragm must not be pressed.

l The connection cable has a capillary for atmospheric

pressure compensation

à Lead the

cable end into a dry space or into a suitable

terminal housing.

Information:

VEGA recommends the breather housing VEGABOX 02 or the

indication/adjustment VEGADIS 12. Both contain terminals

and a ventilation ﬁlter for pressure compensation. For

mounting outdoors, a suitable protective cover is available.

Higher process temperatures often mean also higher ambient

temperatures. Make sure that the upper temperature limits

stated in chapter "Technical data" for the environment of the

electronics housing and connection cable are not exceeded.
