The 22/23 high-performance PTFE butterfly valves from Bray Valve & Controls are available in 14- through 24-inch diameter sizes in both wafer and lug bodies. These large-diameter valves offer the same chemical resistance of PTFE seats and encapsulated discs as the previously available 2- through 12-inch sizes, the company says. The bi-directional pressure rating for the large sizes is 150 psi, and the temperature range is -40 to 392F.
Dyn-X Series pressure transducers from Dynisco Instruments are available in a 6-inch rigid stem configuration and a 6-inch rigid/18-inch flexible stem configuration. The transducers offer full-scale output for selected ranges of 3 mV/V and accuracy of ±1%, providing the user with a non-amplified transducer. Applications include those requiring repeatability and reliability at high process temperatures.
Series 2600 pressure transducers from Gems Sensors Inc. are for submersible applications including well- or reservoir-level monitoring or pump-house environments. An enhanced accuracy option provides an optimum 0.15% static error band and 1% thermal error band over temperature range -4 to 176F.
The A4DO3 directional control valve from Denison Hydraulics features a flow rating up to 80 gm/min and a rated maximum pressure of 5,000 psi. The pilot-operated, two-stage unit has a low pressure drop at maximum flow, and is controlled by solenoids or hydraulic pressure. The electrically operated unit includes the main body and a solenoid-operated pilot valve.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
