Transmitter APRE-2000PZ – version with type C
process connection to mount together with a valve
manifold.

Application and construction
The APRE-2000 transmitter is applicable to the measurement of
differential pressure of gases, vapours and liquids. The active
element is a piezoresistant silicon sensor separated from the
medium by separating diaphragms and a s pecially selected type
of manometric fluid. The special des ign of the active sensing
element ensures that it is able to withstand pressure surges and
overloads of up to 250, 320 or 420bar. Electronics in the casing
with a degree of protection IP65, IP66.

Communication and configuration

The transmitter with P type process connection is not heavy, so it
can be fitted directly onto impulse lines. For fitting in any desired
position on a A an Aplisens mounting bracket (Fi 25
25 pipe
mounting bracket, see page IV/ 5) is recommended.

The communication standard for data interchange with the
transmitter is the HART protocol.
Communication with the transmitter is carried out with:
¨ communicator,
a KAP-03
¨
s ome other HART type communicators ,(*)
¨
a PC with the HART/USB/Bluetooth converter and Aplisens
RA PORT 2 configuration software.
(*) .eddl files available on www.aplisens.com
The data interchange with the transmitter enables the user to:
¨the transmitter;
identify
¨ the output parameters :
c onfigure
– measurement units and values of the start and end-points
of the measuring range;

Installation

The version with C type process connections can be fitted directly to a 3- or 5-valve manifold. We recommend factory-mounted
transmitters with VM type valve manifold (see page IV/ 2). A
transmitter without a valve manifold can be fitted in any position
on a 2" pipe or on a wall using the C-2" mounting bracket (see
page IV/ 5).
When the special process connections are required for the level
measurement of media in clos ed tanks (e.g. in the sugar and
chemical industries) the transmitter is fitted with an Aplisens diaphragm seal. Sets of differential pressure transmitters with diaphragm seals are described in detail presented in the further part
of the c atalogue.
