Field calibration tools deliver efficiency
As plants strive for improved process quality and efficiency, ensuring these signals and variables are accurate is increasingly important.
As plants strive for improved process quality and efficiency, ensuring these signals and variables are accurate is increasingly important. Critical devices are routinely calibrated at prescribed intervals. Technicians often call these activities “ISO” calibrations, referring to the ISO9000 standard that drives many calibration programs. Safety instrument and shutdown systems also require periodic testing and verification.
Process technicians primarily calibrate field instrumentation in place. Modern handheld tools offer accuracies approaching that of bench equipment. Not only can technicians calibrate devices in their operating environment, they save removing/reinstalling the devices and lugging them back to the shop.
With field calibration on the rise, technicians have adopted field calibrators as their tool of choice. The preferred versions combine basic multimeter functions; pressure measurement; a 24-Vdc loop power supply; and the ability to source or simulate 4-20 mA, voltage, thermocouple, RTD and frequency signals. Recent models can also document field calibrations, automatically capture results in the field, upload them to a PC and store them in calibration management software.
As these tools become more powerful, they empower users and ultimately make them more efficient. Technicians don’t need to return to the shop for extra tools, don’t need to take cumbersome bench test equipment into the field or carry a collection of single-function test apparatus. These calibrators are personal tools that create a new breed of high-powered field technicians.

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.
