American Sensor Technologies, Inc. (AST), has expanded its line of non-incendive, intrinsically safe, and explosion-proof pressure transmitter product lines with the addition ofisting ½ in. NPT male pressure port has been popular for its large, non-clogging opening, but the ¼ in. NPT female version gives customers the option to install products as retrofits for existing panels or sites using smaller and lower-cost fittings.

Customers can select a non-incendive, intrinsically safe, or explosion-proof rating depending on the application. The 4300, 4310, and 43LP series combine to offer pressure ranges of 0-2.5 psi to 0-10,000 psi for Class I Division 2 non-incendive groups A, B, C, D applications. The same pressure ranges are available in the 4400, 4410, and 44LP series rated for Class I Division 1 intrinsically safe groups C, D with an approved barrier. Finally, the 4600 will operate in Class I Division 1 explosion-proof groups A, B, C, D areas and 46HA in groups C and D with pressure ranges from 0-50 psi to 0-10,000 psi.

All products can be offered with AST's CSA ANSI/ISA 12.27.01-2007 Single Seal rating for pressure measurement applications in Canada.

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.
