DO7442TC/T DO Sensor Lead Anode, 10ft, TL, TC= by Sensorex

Your Dissolved Oxygen (DO) sensor is a galvanic electrochemical device; i.e. it does not require power from your meter or controller to generate its signal. The DO sensor will provide a millivolt signal proportional to the concentration of oxygen in the water (model DO7400, DO7400TC) or 4-20mA current output (models DO7441 and DO7442). The signal output is proportional to ppm of oxygen for probes with millivolt signal output or changes linearly with ppm of oxygen sensors with 4-20mA output. The partial pressure of oxygen, which is directly proportional to the percent saturation of oxygen in a specified sample, can be calculated based upon the oxygen solubility which is a function of temperature, salinity, total atmospheric pressure, etc.

Your Dissolved Oxygen sensor consists of an cathode, anode and an electrolyte separated from your process fluid by an oxygen permeable membrane. The oxygen passing through the membrane reacts at the cathode, giving up electrons, which produces an electrical current.
