Application and construction
The APR-2000ALW 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 specially selected type of manometric fluid. The
special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/413/700 bar.The
casing is made of aluminium alloy cast or 316SS stainles steel, degree of protection IP66/IP67. The design of the casing enables the use of a
local display, rotation of the display, rotation of the casing by 0–340° relative to the sensor, and a choice of cable direction.
Communication and configuration
The communication standard for data interchange with the The data interchange with the transmitter enables users to:
transmitter is the Hart protocol.
¨ identify the transmitter
Communication with the transmitter is carried out with: ¨ configure the output parameters:
– a KAP-03, KAP-03Ex communicator - measurement units and the values of the start points and end
– some other Hart type communicators(*) points at the measurement range
– a PC using an HART/USB converter and Raport 2 - damping time constant
configuration software. - conversion characteristic (inversion, user's non-linear
(*) .eddl files available on www.aplisens.com. characteristic)
¨ read the currently measured pressure value of the output current
and the percentage output control level
¨ force an output current with a set value
¨ calibrate the transmitter in relation to a model pressure
Installation
The transmitter with P or PN type process connection is not heavy, so can be installed without additional mounting bracket on application. For
fitting in any desired position we recommend an universal Aplisens mounting bracket for 2" pipe (AL mounting bracket, see page IV/ 5). 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 (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 (page IV/ 5). When the special process connections are required for the measurement of specific media levels in closed 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 in the further part of the catalogue.
