Product Details
AOX3100 Full Range Lead-free Oxygen Sensor Electrochemical Oxygen
Concentration Sensor With Temperature Compensation
The AOX3100 is a full - range lead - free oxygen sensor. It is an
electrochemical sensor that detects oxygen concentration based on
the principle of voltage - division electrochemistry. Unlike
traditional sensors using lead (Pb) - based materials, the AOX3100
adopts environment - friendly materials, avoiding lead pollution to
the environment and complying with the RoHS standard.
Features:
- Fast Response: It has a quick response speed, which can quickly
detect the change of oxygen concentration and provide timely
measurement results.
- Long Service Life: With excellent durability, the service life of
the AOX3100 is relatively long, reducing the frequency of sensor
replacement and maintenance costs.
- No External Power Supply Required: The sensor does not need an
external power supply during operation, which is convenient for
installation and use, and can be directly applied to relevant
equipment.
- Pre - calibrated and Temperature - compensated: Each AOX3100 is
professionally and accurately calibrated and temperature -
compensated before leaving the factory, ensuring measurement
accuracy in different environmental temperatures.
Working Principle:
Based on the voltage - division electrochemical principle, when the
oxygen concentration in the environment changes, the
electrochemical reaction inside the sensor will change accordingly,
and the generated electrical signal will also change. By detecting
this electrical signal, the oxygen concentration can be calculated.
Application Fields
It can be used as a sensing component of oxygen analyzers, such as
oxygen - generator control devices, medical ventilators, anesthesia
equipment, incubators, etc.
Technical Parameters:
- Measurement Range: 0 - 100% oxygen concentration (full - range
measurement)
- Output Signal: The specific output signal is related to the oxygen
concentration, and it can output a corresponding electrical signal
within a certain range, which can be used for the subsequent signal
processing circuit to convert into an oxygen concentration value.
- Operating Temperature Range: Usually can work in a certain
temperature range, such as 0 - 40℃ (the specific value is subject
to the product manual, and generally there will be corresponding
temperature compensation within this range to ensure measurement
accuracy).
- Response Time: The response time is relatively short, for example,
the T90 response time (the time required for the sensor to reach
90% of the final value) is less than 5 seconds (the specific value
may vary depending on the product model and actual working
conditions).
