WEIGHTRAC 31 • 4 … 20 mA/HART - four-wire
42374-EN-131119
3.4 Accessories and replacement parts
The display module PLICSCOM is used for measured value indication
and diagnosis. It can be inserted into the sensor and removed at any
time.
The interface adapter VEGACONNECT enables the connection of
communication-capable instruments to the USB interface of a PC. For
parameter adjustment of these instruments, the adjustment software
PACTware with VEGA-DTM is required.
You can find further information in the operating instructions "Interface
adapter VEGACONNECT" (Document-ID 32628).
VEGADIS 61 is an external display unit for sensors with single cham-
ber housing and Ex-d double chamber housing.
It is suitable for measured value indication and is connected to the
sensor with a four-wire standard cable up to 50 m long.
You can find further information in the operating instructions "VE-
GADIS 61" (Document-ID 27720).
The VEGADIS 62 is suitable for measured value indication of sensors.
It is looped into the 4 … 20 mA/HART signal cable.
You can find further information in the operating instructions "VE-
GADIS 62" (Document-ID 36469).
The electronics module PT30E.XX is a replacement part for radiation-
based sensors WEIGHTRAC 31.
The electronics module can only be exchanged by VEGA service
technician.
If you have ordered WEIGHTRAC 31 without a measuring frame, a
basic mounting set is enclosed with the instrument. It includes every-
thing needed to fasten the measuring tube reliably.
The corresponding measuring frame and mounting accessories can
be ordered optionally.
Use a tachometer for detection of the belt speed. The tachometer can
be connected to the input of the WEIGHTRAC 31.
3.5 Corresponding source container
An isotope in a suitable source container (e.g. SHLD-1) is the prereq-
uisite for a radiation-based measurement setup.
The handling of radioactive substances is regulated by law. The radia-
tion protection rules of the country in which the system is operated
apply first and foremost.
In Germany, for example, the current radiation protection ordinance
(StrlSchV) based on the Atomic Energy Law (AtG) applies.
The following points are important for measurement with radiation-
based methods:
Indicating module
VEGACONNECT
External display and
adjustment unit
External indicating unit
Electronics module
Basic mounting set
Measuring frame for
mounting
Tachometer
