These rugged OMEGA zED-P Series wireless transmitters are available with built-in sensors for temperature, humidity and barometric pressure, or inputs for thermocouples and process voltage and current.

The radio is an IEEE 802.15.4 compliant transmitter operating at 2.4 GHz.

Wireless sensors transmit up to 1000m --without obstructions or interferences to a zSeries receiver or wiSeries meter-controller. The receivers and controllers connect directly to an Ethernet network and the Internet and serve active Web Pages to display and chart the data in a standard web browser.

Alarms can be sent by email to a single user or to a group distribution list, including text messages to mobile phones.

These wiSeries wireless sensors are designed for demanding industrial applications indoors and harsh outdoor environments. The electronics are protected in a rugged weatherproof polycarbonate IP65 (NEMA4) rated housing. The industrial sensors are supplied with 3 metres of cable.



Wireless Sensors and Transmitters

Wireless sensors are available with external probes appropriate for an almost unlimited variety of industrial and commercial applications. Wireless transmitters are available for thermocouple or process voltage and current inputs.

Wireless sensor/transmitters run on either batteries or AC power. The battery version (zED-DCELL) comes with two alkaline D-Cell batteries that can last for years. The AC version (zED-P, zED-LCD) comes with a 5 VDC universal AC adapter that operates on any voltage worldwide (110-240 VAC). Should AC power fail, the unit can operate on a 3.6V ultra-long-life lithium backup battery (included). It can run on battery power for days, weeks, or months depending on the user's settings.

Alarms and Email
The wiSeries 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 mobile phones and PDA’s. The OMEGA "MailNotifier" software is a free and easy program for this application.

Embedded Web-Server
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. It serves its own web pages wich can be viewed with your chosen web browser.

Charts and Graphs
The OMEGA wiSeries system serves Active Web Pages to display real time readings and charts. 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 in real-time. 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 wiSeries wireless sensor system with many popular Data Acquisition and Automation programs offered by OMEGA, NEWPORT, Wonderware, iConics, Intellution, Rockwell Automation, and National Instruments, among others.
