 The new OMEGA® zSeries
wireless sensor system provides
Web-based monitoring of
temperature, humidity, and
barometric pressure in critical
HVAC and refrigeration
applications.
The compact wireless transmitters ("End
Devices") mount discretely
on the wall in clean rooms,
laboratories, museums,
computer server rooms,
warehouses, and any remote
facility. The wireless End
Devices are powered by two
"AA" 1.5V alkaline batteries
(included) that are inexpensive
and widely available.
The End Devices transmit
up to 91 m (300') (without
obstructions or interference) to a
receiver ("Coordinator") connected directly
to an Ethernet network and the
Internet. The wireless system
complies with IEEE 802.15.4
operating at 2.4 GHz.
The OMEGA zSeries system
let’s you monitor and record
temperature, relative humidity,
and barometric pressure over an
Ethernet network or the Internet
without any special software-just
your Web Browser.
OMEGA offers a selection of
End Devices for a variety of
applications. Each End Device
supports 1 or 2 sensors. End
Devices are available with built-in
sensors, with external sensor
probes, and with both built-in
and external sensors. The
external sensors are designed
for harsh environments such
as outdoor weather, in
HVAC ducts, in freezers and
refrigerators. For example, you
can select one End Device that
has one internal and one
external sensor to monitor
temperature and humidity both
inside and outside a climatecontrolled
facility.
Each zSeries Coordinator can
directly support up to 32 end
devices. The Coordinators
include AC adaptors to operate
on any voltage worldwide from
100 to 240 Vac and 50 to 60 Hz.
The Coordinator connects
directly to an Ethernet Network
or the Internet. Unlike an RS232
or USB device, it does not
require a host computer.
The zSeries Coordinator is an
independent node on the network sending and receiving data in standard TCP/IP
packets. It is easily configured from a Web Browser and
can be password protected. From within an Ethernet
LAN or over the Internet, the user simply types the IP
address (such as 192.168.1.200) or an easy to
remember name (such as "Warehouse 5" or "Calibration
Lab") and the Coordinator serves a Web Page with the
current readings.
The device can trigger an alarm if variables go above
or below a set point that you determine. Your alarm
can be sent by email to a single user or to a group
distribution list, including text messages to Internet
enabled mobile phones and PDA’s. The OMEGA "Mail
Notifier" software is a free program for this
application.
The OMEGA zSeries wireless sensor system is easy to
install, simple to operate, and features OMEGA’s award winning
iServer technology with an Embedded Web
Server that requires no special software.
The OMEGA zSeries system serves Active Web Pages
to display real time readings and charts of temperature,
humidity, and barometric pressure. You can also log data
in standard data formats for use in a spreadsheet or data acquisition program such as Excel or Visual Basic.
OMEGA offers a free and easy to use program for
logging data to Excel.
The virtual chart viewed on the web page is a JAVA™
Applet that records a chart over the LAN or Internet in
real time. With the OMEGA zSeries system there is no
need to invest time and money learning a proprietary
software program to log or chart the data.
Chart scales are fully adjustable in realtime. For example,
the chart can display one minute, one hour, one day, one
week, one month or one year. Temperature and humidity
can be charted across the full span (-40 to 125°C, and
0 to 100% RH) or within any narrow range such as
(20 to 30°C).
OMEGA offers an OPC Server software that
makes it easy to integrate the zSeries wireless sensor
system with many popular Data Acquisition and
Automation programs offered by Omega, Wonderware,
iConics, Intellution, Rockwell Automation, and National
Instruments, among others.
