The new OMEGA® zSeries wireless sensor system provides Web-based monitoring of Temperature, Humidity, and Barometric Pressure in critical HVAC and Refrigeration applications.

| The End Devices transmit up to 300 feet (without obstructions or interferences) to a “Coordinator” connected directly to an Ethernet network and the Internet. The wireless system complies with IEEE 802.15.4 operating at 2.4GHz. 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 one or two 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 climate-controlled facility. Each Coordinator can directly support up to thirty-two (32) End Devices. TheOMEGA wireless Coordinators include AC adapters to operate on any voltage worldwide from 100-240 Vac and 50-60Hz. The zSeries 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 "Chicago 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 cell phones and PDA’s. TheOMEGA “Mail Notifier” software is a free and easy program for this application. The OMEGAzSeries wireless sensor system is easy to install, simple to operate, and featuresOMEGA'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 OMEGAzSeries 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, and 0 to 100% RH) or within any narrow range such as (20 to 30°C). OMEGA offers an OPC Server software ($295) 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. |
