The FU24 is a 'four in one' pH sensor
The FU24 is a new ‘four in one’ pH sensor designed to offer virtually maintenance-free operation and long sensor lifetime – especially in harsh applications involving severe temperature and pressure fluctuations. The sensor incorporates a bellows system, which automatically compensates for the effect of pressure fluctuations. Such pressure variations can be highly detrimental to sensor operation, as they can initiate a pumping effect resulting from the expansion and shrinkage of the gel or liquid inside the sensor. The outcome is that the process liquid will start to ingress into the sensor and the reference voltage – and hence the pH measurement - will start to drift. In the FU24 sensor, pressure fluctuations are automatically compensated by the built-in bellows up to 10 bar, making the sensor virtually insensitive to pressure variations. A positive overpressure maintained by the tension in the bellows generates a steady flow out of the sensor.

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.
