The new OMEGA

wSeries
transmitters communicate on a
standard Wi-Fi network which is
an ideal and economical solution
for facilities with an existing Wi-Fi
network as well as new installations.

OMEGA offers Wi-Fi transmitters
for analog voltage and current,
temperature from digital sensors and
dual thermocouples, humidity, and
barometric pressure.

Included with Wireless Sensor
System is the Virtual Coordinator,
a data logging software application
running on a computer on the
network. The “VC” collects and
logs data from the transmitters and
serves it to Web browsing clients.

You can view charts and graphs,
monitor and record readings from
virtually any type of transducer over
an Ethernet network or the Internet
from any computer, tablet, or smart
phone with a Web browser.

The Wi-Fi transmitters are powered
by your choice of batteries or AC.
The battery version comes with two
ordinary alkaline “C-cell” batteries
that can last for 2 years depending
on the frequency of readings. The
AC version comes with a universal

AC adaptor that operates on any
voltage worldwide (110 to 240 Vac)
and also includes an alkaline “AA”
backup battery.

The wSeries Wi-Fi transmitters are
designed for demanding industrial
applications and harsh outdoor
environments. The electronics are
protected in a rugged weatherproof,
polycarbonate NEMA 4 (IP65)
rated housing.

Alarm and Email

The wSeries wireless sensor system
can trigger an alarm if variables go
above or below a set point that you
determine. You can even set alarms
to be notified by email. Alarms can
be sent to a single user or to a
group distribution list, including text
messages to cell phones.

Charts and Graphs

The wSeries system serves active
web pages to display real time
readings and charts of analog
voltage and current, temperature,
humidity, and barometric
pressure. You can also log data in
standard data formats for use in

wTHP2-LCD-CCELL
shown smaller than
actual size.

a spreadsheet or data acquisition
program such as Excel or Visual
Basic.

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 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 wSeries
wireless sensor system with
many popular data acquisition
and automation programs offered
by OMEGA, Wonderware, iConics,
Intellution, Rockwell Automation,
and National Instruments, among
others.

Quality and Technology

The innovative wSeries system
features an extended one year
warranty at no extra charge.
