Steam-sterilizable pH sensor resists cracking
Autoclavable and steam-sterilizable pH sensor <br/><br/>
The Rosemount Analytical PUR-Sense 3800 from Emerson Process Management is an autoclavable and steam-sterilizable pH sensor that reportedly delivers sensor stability as much as five times greater than any other pH sensor. High temperature can cause deterioration of a pH glass sensing membrane; however, the AccuGlass pH bulb on the Rosemount Analytical PUR-Sense 3800 resists cracking and aging and exhibits near theoretical response even at extreme pH values, according to an Emerson Process Management spokesperson.
In simulated cell-culture process, the product exhibited sensor drift below 0.1 pH after an autoclave of 125 °C for 45 minutes. Testing showed continued sensor life after more than 30 autoclave cycles or 50 steam cycles. PUR-Sense reference electrode uses a silver-silver chloride-based reference electrode in combination with a new gelled potassium chloride electrolyte to provide a stable reference potential through the single proprietary ceramic reference junction. It provides an individual quality certification with calibration records and list of wetted materials for each sensor.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
