What is Advanced Galvanic Sensor Technology?

All galvanic type sensors work on the same principle and are very specific to oxygen. The sensors measure the partial pressure of oxygen from low PPM to percentage levels in gaseous hydrocarbons, inert gases, hydrogen, helium, ambient air, acid gas streams, and mixed gases.

The fuel for this electrochemical transducer is oxygen, which diffuses into the sensor and chemically reacts at the sensing electrode to generate an electrical current output proportional to the oxygen concentration in the gas phase. The signal output of the sensor is linear and stays almost constant throughout its service life. The sensor does not require any maintenance and can be easily and safely replaced at the end of its service life.

Proprietary improvements in the chemistry and design add considerable benefits to a highly adaptable oxygen sensing technology. Sensors intended for low PPM analysis recover from air to low PPM levels in minutes and have longer service life, exceptional compatibility with CO2 and other acid gases (XLT series sensors only), extended operating temperature range of −20 °C to 50 °C, and reliable quality, being beneficial over other competitive devices.

The anticipated service life of the new generation of percentage range sensors ranges from 5 to 10 years with greater stability and quicker response times. Other important developments are the first galvanic oxygen sensor with the ability to continuously measure oxygen purity and expand the operating temperature range from −40 °C to 50 °C.
