Oxygen Sensor FAQ
What is a galvanic oxygen sensor?
A galvanic oxygen sensor is an electrochemical device that measures oxygen concentration through a chemical reaction between oxygen and internal electrodes immersed in an electrolyte. This reaction generates a millivolt (mV) signal proportional to the oxygen level, making it ideal for both medical and industrial use.
How does a galvanic oxygen sensor work?
Oxygen diffuses through a membrane into the sensor, where it reacts with the electrodes. This chemical reaction produces a small voltage (typically ~14.5 mV in air), which correlates directly to the oxygen concentration.
What is the standard output of a galvanic oxygen sensor in air?
Under standard atmospheric conditions (20.9% oxygen), the typical output is approximately 14.5 mV. This output can be customized for compatibility with specific OEM devices.
Can the sensor output be customized for specific equipment?
Yes, we offer calibration services to adjust the sensor’s mV output to match the specific input requirements of your medical or industrial equipment.
What are the key advantages of galvanic oxygen sensors?
- Accurate and rapid oxygen level detection
- Long-term output stability
