Sampling System

The EC2000 needs an external sampling system able to deliver an almost clean sample gas to the analyser at the proper temperature, pressure and flow rate.

ADEV has a wide experience in process and can provide the EC2000 analyser combined with a sample and condition system designed for the specific application requirements. Contact ADEV for details.

Measuring Principle

The sensors are specific for Oxygen. They measure the partial pressure of Oxygen from low ppm to 100% levels in inert gases, gaseous hydrocarbons, helium, hydrogen, mixed gases, acid gas streams and ambient air.

Oxygen, the fuel for this electrochemical transducer, diffusing into the sensor reacts chemically at the sensing electrode to produce an electrical current output proportional to the Oxygen concentration in the gas phase. The sensor’s signal output is linear over all ranges and remains virtually constant over its useful life.
