SENSORS: The PX309 Series pressure transducers from OMEGA employ the latest aerospace silicon technology and offer a choice of absolute pressures from 5 to 300 psi, gage pressures from 1 to 10,000 psi and three output ranges, 0 to 100 mV, 0 to 5V dc and 4 to 20 mA, which makes them compatible with most process-control equipment. All stainless-steel construction provides the durability needed for industrial applications. The transducers use the latest semiconductor sensor technology. Pressure ranges 50 psi and below plus all absolute pressure ranges use a high stability semiconductor pressure sensor isolated via a fluid-filled, stainless-steel diaphragm system. Pressure ranges 100 psi and above use high-accuracy silicon strain gages molecularly bonded to a stainless-steel diaphragm. Both systems provide a rugged sensor with high accuracy and excellent long-term stability. Three connection styles are available: 1.5 m (5 ft) cable, mini DIN (mating connector included) and military-style twist-lock. All models are RoHS and CE compliant. Prices start at $175.
Major global metropolitan areas are implementing a vast number of technology, energy, transportation, and Internet projects to make the metropolis a friendlier, greener, safer, and more sustainable place to be.
Here’s a look at robots depicted in movies and on TV during the 1950s and 1960s. We tried to collect the classics here, omitting the scores of forgettable B movies such as Santa Claus Conquers the Martians and Dr. Goldfoot and the Bikini Machine. Stay tuned for slideshows of robot stars from later decades.
