Kimessa GSE401 Oxygen O2 Gas Sensors

GSE401 Oxygen O2 Gas Sensors Description

The principle of the measurement cell used is based on the diffusion of oxygen. The O2 diffuses through the gas-permeable diaphragm onto the gold cathode, and is reduced on it.
The current flowing between the electrodes is proportional to the concentration, and will then be amplified and be led to the evaluation device by the transmitter.
The measured gas concentration is linear to the electrical output signal of the gas measurement probe. The potentiometers and the 3.5 mm jack connection for the calibration are accessible from the outside, and permits a "one-man" calibration.
When used in a pump system, the service life can be heavily reduced, as the electrolyte evaporates more quickly through the porous diaphragm. The measurement cell is sensitive to solvent vapours.
