4.1 General instructions

The pressure transmitters VEGADIF 65 are equipped with a two-part

electronics: the meas. cell and the processing electronics. The meas.

cell electronics in the process ﬁtting is not accessible to the user. The

processing electronics, as an electronics module, is located in the

housing. In case of a defect, the electronics module can be exchanged

by the user.

In Ex

applications only one instrument and one electronics module with

respective Ex approval may be used.

If no electronics module is available on site, it can be ordered from the

VEGA agency serving you. The order is possible without or with

sensor serial number. The serial number is stated on the type label of

the instrument or on the delivery note.

The electronics module without serial number contains no order-

speciﬁc data. However, operation of the instrument is also ensured

without these data. This allows a "universal electronics module" to be

kept in stock for several instruments.

The electronics module with sensor serial number contains order-

speciﬁc data such as housing material, process ﬁtting, meas. cell

seal, etc.

4.2 Mounting preparations

First of all, check by means of the order code if you are using the

suitable electronics module:
