Self Calibration by ABCLogic
Virtually all gas sensors are subject to some sort of drift. The degree of drift is partially depending on the use of quality components and good design. But even with good components and excellent design a small amount of drift can still occur in the sensor that may ultimately result in the need for a sensor to be recalibrated.Generally, recalibration involves a maintenance person visiting each sensor in a building and performing a 5 minute to 20 minute recalibration routine using gas bottles and plastic tubing.
The calibration process is simple but it can turn into a significant expense if recalibration is required frequently. If the wrong choice of sensors is made, the expense of sensor maintenance may wipe out any potential energy savings that could come from CO2 based demand controlled ventilation.
How Thermokon sensors are differing from other devices?
Thermokon sensors have an automatic self-calibration counteracting this behaviour by an intelligent software and a dynamic offset evaluation. Thus, there is in principle no necessity for a re-calibration of the sensor duringoperation.
Many years of experience with the self-calibration ABCLogic? prove the good features of the sensors.
