4 Mounting
4.1 General instructions
The pressure transmitters of VEGABAR series 50 and 60 are
equipped with a two-part electronics:
•
Measuring cell electronics
•
Processing electronics (electronics module)
The measuring cell electronics is located in the process fitting. It is not
accessible to the user.
The electronics module is located in the sensor housing and can be
exchanged by the user in case of a defect.
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.
Without serial number
The electronics module without serial number contains no order-
specific data. However, operation of VEGABAR is also ensured
without these data. This allows the stocking of a "universal electronics
module" for multiple VEGABAR sensors of different types.
With serial number
The electronics module with sensor serial number contains order-
specific data such as housing material, process fitting, measuring cell
seal, etc.
4.2 Mounting preparations
The electronics modules differ in their signal output, e.g. 4 … 20 mA/
HART.
There is another difference in the version "Standard" or "Climate com-
pensated". The version "Climate compensated" can be recognized by
the additional specification "climate compensated" on the type label
of the electronics module.
Note:
Make sure that you are using the correct version of the electronics
module. Otherwise, the air pressure compensation or the measure-
ment data processing will not be correct. The result is the output of
incorrect measured values to the signal output.
The electronics module BR-E.50Z. is suitable for all VEGABARs of
series 50 with signal output 4 … 20mA.
The electronics module BR-E.50H. is suitable for all VEGABARs of
series 50 and 60 with signal output 4 … 20mA/HART.
The electronics module BR-E.50K. is suitable for all VEGABARs
of series 50 and 60 with signal output 4 … 20mA/HART - climate-
compensated

cessing electronics
