The wiSeries 1⁄8 DIN panel meter and controller can
monitor up to 8 wireless sensors.
The compact instrument connects directly to an
Ethernet network and the Internet and features
OMEGA’s award-winning embedded Web Server. It is
easily configured and monitored with a Web browser
over the Ethernet network or the Internet.
Alternatively, the wi-8 meter-controller can instead be
connected to the USB port of a single computer with
a “USB Ethernet Adaptor” that are inexpensive and
widely available.
MONITOR AND ALARM
The wi-8 meter-controller comes standard with a choice
of either two Form C relays, or two SSRs (solid state
relays) that can be used for control functions or alarms.
The wi-8 meter can monitor alarm conditions for any or
all of the wireless sensors. For example, the wi-8 meter
can be set up to trip an alarm if any one of the sensors
indicated it was above or below a pre-set alarm point.
MONITOR AND CONTROL LOCALLY AND
OVER THE INTERNET
The new OMEGA® wiSeries wireless monitoring and
control system provides local monitoring and control,
along with remote Web-based monitoring of temperature
from thermocouples, RTDs, and semiconductor sensors.
The wireless sensors transmit up to 1000 m (3280')
(without obstructions or interference) to a wiSeries
monitor-controller connected directly to an Ethernet
network and the Internet. The wireless system complies
with IEEE 802.15.4 operating at 2.4 GHz.
Note: Distances for UWTC-1, UWRTD-1: up to 60 m (200'), UWTC-2,
UWRTD-2: up to 120 m (400'), zED-x-P: up to 1000 m (3280'), zED-x:
up to 90 m (300') all distances without obstructions or interference.
The OMEGA wiSeries system let’s you monitor and record
temperature over an Ethernet network or the Internet
without any special software—just your Web Browser.
WIRELESS SENSORS
OMEGA offers a wide and growing selection of wireless
sensors for a variety of applications. Depending on
application, the wireless sensors are powered by 2 “AA”

batteries, a single lithium battery (approx “AA” size),
2 “D” cell batteries, or an external AC Adaptor that
operates on any voltage worldwide from 100 to 240 Vac.
Wireless sensors are available with external probes
appropriate for an almost unlimited variety of industrial
and commercial applications.
ETHERNET
The wiSeries meter-controller-scanner 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
“Oven 5” or “Chicago Test Fixture”) and the wiSeries
meter serves a Web Page with the current readings.
ALARM AND EMAIL
The wiSeries meter 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 cell
phones and PDAs. The OMEGA “Mail Notifier” software
is a free and easy program for this application.
The wiSeries meter-controllers operate on any AC
voltage worldwide from 90 to 240 Vac and 50 to 60 Hz.
The meter-controller connects directly to an Ethernet
Network or the Internet. Unlike an RS232 or USB
device, it does not require a host computer.
EMBEDDED WEBSERVER
The OMEGA wiSeries 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.
CHARTS AND GRAPHS
The OMEGA wiSeries system serves Active Web
Pages to display real time readings and charts of
temperature. 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 wiSeries 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 on the fly. For
example, the chart can display one minute, one
hour, one day, one week, one month or one year.
Temperature can be charted across the full span
(-40 to 125°C), or within any narrow range such as
(20 to 30°C).

WIRELESS METER SCANNER AND CONTROLLER
A complete wireless system requires at least 1 receiver (wi8XX) and 1 end device (UWTC or zED).
OMEGA offers an OPC Server software that makes
it easy to integrate the wiSeries wireless sensor system
with many popular Data Acquisition and Automation
programs offered by OMEGA, Wonderware, iConics,
Intellution, Rockwell Automation, and National Instruments,
among others.
at any set point
PROGRAMMABLE COLOR DISPLAY
The OMEGA wiSeries feature OMEGA’s patented
programmable color displays. The display can be
programmed to change color at any set point or alarm point
For example, the wiSeries can be programmed to display
the process value in GREEN during warm-up, switching
to AMBER to signal the normal operating range, and in
RED to signal an alarm condition. The changes in color are
quickly seen from a distance, and machine operators can
intuitively react to changing conditions. The colors can be
programmed to change back when the value drops back
below the alarm point or to “latch” on until being reset by
the operator.
The wiSeries can also be programmed to display only one
unchanging color: GREEN, AMBER, or RED. This is a
useful way to let an operator identify, at a glance, process
values in three separate locations, or to display three
different measurements such as Temperature, Pressure,
and Flow.
QUALITY AND TECHNOLOGY
Designed and manufactured in the USA, the innovative
OMEGA wiSeries of meters and controllers features an
extended 1 year warranty at no extra charge.
