Oxygen concentration sensor GSK2

The GSK2 sensor is an electronic device designed for measuring oxygen (O₂) concentration in the air. Its primary use is in residential spaces, laboratories, and various technological operations where continuous oxygen concentration monitoring is required.

The output is a current signal compliant with the industrial standard – a 4–20 mA current loop. GSK2 sensors are connected to a supervisory system (control computer, evaluation unit, etc.), transmitting a proportional signal corresponding to the measured concentration. The connection is made via a two-wire setup, where the output signal corresponds to the current drawn by the sensor.

The electronic board features two adjustment elements that allow setting the baseline output current level and the correct current corresponding to the measured gas concentration. The sensor's electronics are housed in a plastic enclosure designed for mounting on a solid surface using two screws.
