Differential pH Design Overcomes Common pH Sensor Challenges
2015-03-09 01:27:16| chemicalonline Home Page
All pH measurement systems operate on the principle of an electrochemical cell; that is, when two dissimilar conductors are placed in an electrolyte (a liquid capable of carrying a charge) they will develop a potential between them.

Differential Pressure Transducers utilize solid state sensor.
2015-01-22 14:31:53| Industrial Newsroom - All News for Today
Based on micromachined silicon sensor, PX509HL Series provides stable reading with accuracy of 0.08% and broad compensated range of -20 to 85°C. Wet/wet differential pressure transducers operate in demanding industrial areas with ruggedized containment pressure up to 10,000 psi. Compensated overload range minimizes errors induced by large line pressures. Constructed of welded stainless steel, modular transducers offer user accessible potentiometers for zero and span.

Proving Airflow: Zero Speed Switches vs. Differential Pressure Switches
2014-12-12 11:30:52| Industrial Newsroom - All News for Today
A key component to any industrial oven is the safety interlock circuit. This circuit may be comprised of any number of different interlocks. An interlock is defined as any device that is used to prevent an undesired state in a machine or piece of equipment. The information contained in this paper will focus on...

Energy Conflicts and Differential Profits
2014-11-03 01:11:22| Energy - Topix.net
During the late 1980s and early 1990s, we identified a new phenomenon that we called 'energy conflicts' and showed that these conflicts were intimately linked to the differential profitability of the leading oil companies. Figure 1 below, which was first published in 1995, adds new data to bring this connection up toA date.
