Promote sustainable building practices with the LS-301 Dimming Photosensor from Watt Stopper/Legrand. The model features a handheld setup remote to facilitate quick and convenient commissioning. All adjustments are made using an intuitive remote control, so there is no need for tools or ladders. An optional occupant remote control permits the automatic lighting level to be temporarily overridden, if needed, without changing the setpoints. The LS-301, which controls standard 0 to 10 V dc electronic dimming ballasts, can be used as one element of a green lighting design that minimizes energy use and keeps operating costs in check. The model's sliding setpoint algorithm allows the controller to compensate for the disparate spatial distribution of daylight and electric light. By having two different setpoints for day and night, the target setpoint changes based on the current light level conditions. Additionally, the spectral response of the LS-301's photodiode has been carefully tuned to match the photopic curve; the light perceived by the human eye. By sensing only visible light, the photosensor does not over-dim or under-dim. Together, these features result in a balanced contribution of electric light at all times, that adjusts subtly and is comfortable for occupants.

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.
