Abstract

A contacting-type conductivity sensor (10) includes an electrically-insulative plastic body (20) and a plurality of electrodes (12, 14, 16, 18). The plurality of conductive electrodes (12, 14, 16, 18) is disposed in the plastic body (20). Each electrode (12, 14, 16, 18) is constructed of plastic and fused with the electrically-insulative plastic body (20). A method of manufacturing the conductivity sensor is provided along with a single-use bioreactor (50) employing the sensor (10).

Description

technical field

[0001] Liquid conductivity measurement systems are used to measure the conductivity of water and aqueous or non-aqueous solutions in environmental, medical, industrial and other applications where an indication of the ionic content of the liquid is required. Background technique

[0002] Liquid conductivity was measured in each case to provide a parameter that may be related to bulk ionic concentration. In cases where a single type of ion is present, the conductivity may actually be related to the specific ion concentration. Even in the presence of several different ionic compounds, the measurement of the bulk conductivity of a liquid can still provide very useful information. Accordingly, conductivity measurements have been widely adopted and utilized by industry for a variety of different purposes.

[0003] Typically, a contact conductivity measurement system includes a conductivity cell and an associated conductivity meter. figure 1 Such a system is ill...
