Wi-fi wireless sensor system
The W-series wireless transmitters are designed to measure analog voltage and current, temperature, humidity and barometric pressure.
The Omega wSeries transmitters communicate on a standard Wi-Fi network and offers Wi-Fi transmitters for analog voltage and current, temperature from digital sensors and dual thermocouples, humidity, and barometric pressure.
The Wi-Fi transmitters are powered by 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 V ac) 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.
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.
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 a spreadsheet or data acquisition program such as Excel or Visual Basic.
Chart scales are also adjustable. 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).

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
