Ultra-compact sensors: Gage and differential pressure in small package

Analog output allows for smaller transmitter profile.


The new GC51 and GC52 gauge and differential pressure transmitters from Ashcroft offer an economical choice for analog output in cramped quarters.

If you don’t need a digital communication protocol, this design features an ultra-compact NEMA 4X/IP65 enclosure measuring only 2.65 in. in diameter. Stainless steel wetted parts accommodate either wet or dry media. The GC51 is available in ranges up to 0-7500 psig (517 bar) and the GC52 offers differential pressure ranges up to 400 in. of water (1 bar). A built-in LED display and a 4-20 mA output provide both local indication and remote signaling. The company says GC series transmitters are ideal for measuring fluid levels in tanks, water towers and across differential pressures membranes in water purification systems. Media isolators are available for sludge or caustic media installations.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
