The Walker Art Center is home to an in-depth collection of Oldenburgâs work, ranging from early performance-related objects to large-scale outdoor sculpture to drawings, prints, multiples, and rare studies.
Chemoreceptors detect the levels of carbon dioxide in the blood by monitoring the concentrations of hydrogen ions in the blood. Learning Objective. Describe the role of chemoreceptors in the regulation of breathing. An increase in carbon dioxide concentration leads to a decrease in the pH of blood due to the production of H+ ions from carbonic acid.
Potentiometric Position sensors. Potentiometric position sensor use resistive effect as the sensing principle. The sensing element is simply a resistive (or conductive) track. A wiper is attached to the body or part of the body whose displacement is to be measured. The wiper is in contact with the track.
