P200 and P290 pneumatic-to-current P/I transducers are designed to convert standard 3-15, 3-27, or 6-30 psig air pressures into a two-wire 4 to 20 or 10 to 50-mA signal with a total accuracy up to ±0.10%. Customized inputs as low as 0 to 20-in. w.c. or as high as 0 to 50 psig are readily available.
Pneumatic cylinders put their interior hardware through quite a stress test. To lessen the effects those stresses have on shortening the cylinder's operational life and causing maintenance problems, engineers at Ace Controls Inc. developed NuCushions.
Advances in controls and networks combined with components that pack more punch have opened the door to more-precise, durable, and economical pneumatic systems.
A new hydraulic pressure switch from Norgen-Herion, Warrendale, Pa., relies on solid-state electronics for its reliability, fast switching (less than 10 msec), and long life -up to 100 million cycles.
