Capacitance type level limit detection has been widely used in the past to solve level detection problems in various applications. Their successful operation used to depend on the knowledge and experience of site conditions and skill of calibration. Vector series of compact capacitance switches have this intelligence built into the system and so do not need complicated skilled calibration. It is simply plug and play , fit and forget concept.
The moment the instrument is installed and switched and switched ON it evalutes the initial capacitance and waits for the material level to rise. When covered, it detects the material and indicates the status. When the level recedes it automatically tunes to the ne value of capacitance that may have occurred occurred due to change in environment in the vicinity of the probe, or due to residual material coating.
It is now ready to detect the next rise in level. The auto tuning is refreshed every emptying cycle, thus, maintaining appropriate sensitivity throught.
Slow changes due to changes in moisture, humidity and temperature are also taken into account by the long term filtering and averaging algirithm thereby making the system very reliable.
