TDK Product Features

TDK's portfolio of level sensors includes piezoelectric powder level sensors, which employ piezoelectric sensor elements.
These sensors feature a built-in oscillating circuit, which causes them to vibrate.
The sensor elements are able to detect the presence of powder when they come into contact with powder and their vibrational conditions are altered.
The portfolio of level sensors is rounded out with PTC level sensors, which are designed to indicate the presence or absence of various liquid media.
