Figure 1b is a linear potentiometric pressure sensor. "solid-state" thermal isolation structure on the sensor die eliminates the need for surface cavity or fragile membrane used in competing technologies, making the sensor resistant to clogging and pressure shock. The potentiometric pressure sensor provides a simple method for obtaining an electronic output from a mechanical pressure gauge. of a broad range Alfa Laval offers a broad range of tank instrumentation for use in brewery, food and beverage, biopharm industries. Flush panel mounting, pipe mounting, and surface mounting as well as portable kits are available for various field applications. Thermoelectric …. By convention, the measuring electrode is considered as the cathode in potentiometric sensors. Potentiometric biosensors usually rely on a biochemical reaction leading to a simpler chemical specie and its subsequent electrochemical detection (NH 4 OH, CO 2, pH, H 2 O 2, …). Description: It can be used with pitot tubes to measure velocity and then calculate flow rates with user–input duct size and shape. They are intended to be used with dry and non-corrosive gases. The sensor defined in claim 9 wherein: 11. It also features ten point linearization, Description: These extremely rugged devices utilize both bourdon tube and capsule pressure sensors for the best value-performance match. Principle of Working of Potentiometers The potentiometer is also called as pots and it one of the most commonly used devise for measuring the displacement of the body. Description: It consists of a measuring (working) electrode, a gas selective membrane, and a reference electrode-together forming a sandwich with the membrane in the middle.
