XYR5000 Analogue Input Transmitter
The WI550 Analog Input Field Transmitter is part of
the XYR 5000 family of wireless products. It is used
to add wireless capabilities to new or existing
analog transmitters, such as pressure, temperature,
level, flow meters, pH meters, or any device that
has voltage (0 – 10 V) or current (4 – 20 mA)
outputs. The Smart 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. Optional discrete inputs are available for
The transmitter combines a high resolution signal
conditioner, with a Radio Frequency (RF) transceiver
that communicates in 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.
Features
-
There are four models of Analog Input Transmitters:
- WI551 : Dual Analog Input Interface (4-20 mA) with Omni
Directional Antenna
- WI552 : Dual Analog Input Interface (0-10 V) with Omni
Directional Antenna
- WI551 : Dual Analog Input Interface (4-20 mA) with Yagi Antenna
- WI552 : Dual Analog Input Interface (0-10 V) with Yagi Antenna
-
The dual analog input transmitter comes in current (4-20 mA) or
voltage (0-10 V) packages, each accepting up to two inputs.
