The rate of reaction in terms of quantum yield was determined by passing monochromatic light of 657 nm through the reaction mixture and the photo cell
responses were recorded.
In addition, the photo cell
with adapter has one and a half times the capacity of the BA-5368/U.
Designed for home and small office settings where extra security is needed, this unit features automatic start/stop via photo cell
, a three-position rocker switch (for stand-by, stop, and reverse), and an optical power indicator.
* Energizer lithium photo cell
, a AA battery ideally suited for digital cameras.
The SCADA features a sophisticated alarm management system, which is able to detect line blockages, conveyor belt motor failure or photo cell
The door, which slides up and down, is operated by a motor which gets its command from a 120 volt photo cell
of the type used to operate night security lights and available at most hardware stores.
In the demonstration, the parison dropped about 4 ft until it reached a photo cell
. Then a gripper cut it off and lowered it into the tool, where a second gripper closed on the bottom of the parison.
If the sand is dry, it falls through a slot where a photo cell
sensor detects the material and adds water to the muller.
A photo cell
stops the conveyor if the robot is not available.
To interlock and sequence the restraint with other dock equipment, proximity and photo cell
sensors are integrated into the unit.
The door is equipped with an electrically monitored contact safety edge and integrates a door line stationary photo cell
, which automatically stops the door if it senses an obstruction and returns it to its open position.
Energy-saving technology installed at Baxter facilities has included replacing T-12 lamps with T-8 lamps, which are 1/2-inch smaller in diameter; replacing incandescent lights with fluorescents; installing electronic ballasts, which are about one-third more energy efficient than standard ballasts; using timers and darkness-activated photo cell
equipment for outdoor lighting; and placing occupancy sensors in specified areas.
