A pH sensing bioreaction system is provided. The system includes a bioreaction container having a plastic wall and a pH sensor attached to the plastic wall. The pH sensor includes a sensor body having a flange that is sealingly attached to the plastic wall. The sensor body has a reference electrolyte therein and a first sensing element disposed in the reference electrolyte. The first sensing element is configured to contact both the reference electrolyte and a sample solution inside the bioreaction container. A second sensing element is positionable into an interior of the bioreaction container. The pH sensor has a plurality of configurations that include a booted configuration in which at least one sensing element is isolated from the interior of the bioreaction container, and a service configuration in which the at least one sensing element is fluidically coupled to the interior of the bioreaction container.

pH sensor integration to single use bioreactor/mixer

A pH sensor is provided. The pH sensor includes a body, a glass electrode, a reference electrode and a solution ground. The glass electrode is disposed on the body to contact a liquid sample. The reference electrode has a reference fill solution disposed within the body. The solution ground electrode is operably coupled to the body and has a portion of the solution ground electrode that is disposed within a harbor such that a portion of the solution ground electrode is configured to contact the liquid sample. The body has a passageway that extends from the reference fill solution to an aperture proximate the liquid sample.

High purity water pH sensor with shielded flowing liquid junction

An industrial process sensor includes a proximal end, a distal end, a longitudinal axis and an outer diameter surface. A cam follower surface is recessed into the outer diameter surface. A diameter reduction is formed on the outer diameter surface, between the cam follower surface and the distal end. The diameter reduction defines an annular process sealing shoulder that faces the distal end and lies in a plane intersecting the longitudinal axis. A sensor element is carried at the distal end. A cable is electrically coupled to the sensor element and extends from the proximal end.

Quick-connect industrial process sensor

An inductive conductivity sensor is immersed in a liquid to measure its conductivity. The sensor comprises a transducer for generating a changing magnetic field and for inductively measuring an electric current induced in the liquid by the changing magnetic field. The transducer has an external surface facing the liquid. A elastic membrane separates the external surface from the liquid. The elastic membrane is periodically inflated and deflated to deform its outer shape and thereby remove deposits formed on the membrane.
