The gas sensor KSPC 121 is used for the detection of explosive gas/vapour/air mixtures with a range of 0-100 % LEL.

The complete range of gases and vapours that the KIMESSA KSPC 121 can detect is provided in the Kimessa Detector Catalogue that can be downloaded here.

The principle of the measurement element used is based on the catalytic combustion caused by the detected gas/vapour/air mixture. The reaction heat that is released causes an increase in the temperature of the platinum wire to which the catalyst is attached. The current flowing through the platinum wire increases, and is proportional the measured gas concentration up to approx. 10 Vol. % methane. The signal then reduces again as a result of the shortage of oxygen.

Depending on the use and the application, the required measurement element will be integrated into the measurement probe, i.e., various measurement elements are available, which must be taken into account when replacing them.

The potentiometers and the 3.5 mm jack connection for the calibration are accessible from the outside, and permits a “one-man” calibration.
