Lots of explanation about the signal output, pressure, and temperature compensation are presented inside the application note. In this application note you can learn description regarding sensors, output signal, and oxygen.
This application note contains explanation like output range, compensation, and signal. Below are selected from this application note:
Liquid/Moisture: Condensation on the sensing surface of the sensor reduces the signal output by blocking the diffusion of oxygen into the sensor and is mistakenly categorized as a sensor defect. e) repeated exposure to CO2 of 3-4 hours can result in a temporary loss of signal output, see Carbon Dioxide CO2 Diving sensors are then equipped with a PCB that includes the appropriate electrical connector and the temperature compensation network which converts the current (µA) signal output to (mV) output. As illustrated below, individual test reports are generated for every sensor and identify the sensor by model, serial number, date and time tested, accompany every sensor shipped.
Furthermore, this application note tells us more such as circuit, and sensor.
