Wireless Indoor Air Quality Monitor
PPM Technology’s newest IAQ monitoring system, the Wireless IAQ Profile PPMonitor, enables simple, effective and flexible management of the indoor air environment.
The PPMonitor can continuously detect, measure and record a number of parameters, including temperature, humidity, formaldehyde, nitrogen dioxide, carbon monoxide, carbon dioxide, sulphur dioxide, ozone, ammonia and TVOC’s. Real-time functions enable immediate warnings of the presence of harmful gases in the air, thus protecting employees and the public. Hence buildings can be immediately evacuated giving minimal exposure to the building occupants.
The system has been designed to be easily set-up and operated. A manager PC simply connects to the wireless network using a Telegesis ZigBee USB module, allowing for the transmitting and receiving of information to and from a particular wireless unit.
The wireless units communicate via the ZigBee wireless mesh network which can be extended easily by adding repeater nodes or additional PPMonitor or Mini PPMonitor units. Each unit can be configured with unique sensor specifications if required, allowing complete monitoring of the indoor air environment in any building layout.
One wireless unit is connected to the Building Management System; BMS Software allows the entire wireless system to be managed from a single PC, the PC can preset a number of different exposure levels to trigger when limits are exceeded; these could be visible or audible alarms or used to control 3rd party systems such as ventilation systems.
The PPMonitor software enables the data to be viewed graphically and to produce reports and statistical data. Analysis of the recorded data over time allows for more efficient management of resources and energy.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
