XYR 5000 WD520

Wireless Differential Pressure Transmitters Europe

34-XY-03-57 9/2006 PRODUCT SPECIFICATION AND MODEL SELECTION GUIDE

Function

The WD520 is part of the XYR 5000

family of wireless products. These
transmitters cover a wide differential
pressure range, and can be used to
monitor a variety of processes and
assets in hazardous and remote areas.
The WD520 can be set to operate in
four modes: differential pressure,
orifice flow, open channel flow, and
level. Since there are no wires to run,
the transmitter can be installed and
operational in minutes, quickly
providing information about the
variable being monitored. The Smart Base Radio
Response Manager allows the
transmitter to adapt to changing
process conditions, allowing greater
visibility to process variation. Smart
Response Manager allows the user to
set thresholds which, when exceeded,
cause the transmitter to adjust
sampling and data transmission rates.
The transmitter combines a differential
pressure sensor with a Radio
Frequency (RF) transceiver operating
in the 868 MHz ISM license-free band.
Communication is a digital protocol,
using Frequency Hopping Spread
Spectrum (FHSS). FHSS ensures data
integrity by continually switching the
carrier wave over a wide range of
frequencies. Power is supplied by a C
size 3.6 V lithium battery, with an
expected lifetime of up to five years.

SITE SURVEY TOOLS

RSSI Received Signal Strength Indicator displays the RF signal strength in one of seven
ranges.
Link Test Link Test measures the wireless link performance of a transmitter running in normal
operating mode. This function looks at wireless performance in both directions, from
the transmitter to base radio and vice versa and assigns a rating to that performance or
quality of signal.

FEATURES
Automatic Re-transmit The field unit checks with the base radio to insure successful receipt of data. If data
was not received, the transmitter retries on the next RF cycle. Ensures communication
confidence in the harshest of industrial environments.
At the maximum transmit rate this feature is inactive.
