Wireless Transmitters
Wireless transmitters are available with external probes
appropriate for an almost unlimited variety of industrial
and commercial applications.
OMEGA offers a selection of end devices for a
variety of applications. The high power end device
supports one external sensor. The external sensors
are designed for harsh environments such as outdoor
weather, in HVAC ducts, in freezers and refrigerators.
The high power end devices run on either AC power,
low voltage power, or batteries. The AC version (zED-P,
zED-LCD) is powered by a 5 Vdc universal AC power
adapter that operates on any voltage worldwide (110 to
240 Vac). Should AC power fail, the unit can operate on
a 3.6V ultra-long-life lithium back-up battery (included).
A low power option (zED-DC) operates at 10 to 30 Vdc,
or 24Vac. The completely wireless End Devices are
powered by two AA (zED-LCD-AA) or two C-cell (zED-
CCELL) alkaline batteries. These End Devices can
operate for weeks, months, or years before changing
the batteries. Battery life depends on the type of sensor
and other user settings such as the frequency of
transmission.
Alarm and Email
The zSeries wireless sensor system 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 “MailNotifier” software is a free and
easy program for this application.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 Web Server
The 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 zSeries 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 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 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 (-40 to 257°F), and 0 to 100% RH]
