High frequency type sensing device |
摘要 |
A sensing device in which a high frequency signal is transmitted from an oscillator to a sensor through a transmission path, a reflection signal generated according to a variation of an impedance of the sensor sensing the presence or absence of an article is detected by a reflected wave sensor, and the presence or absence of the article is detected by the presence or absence of the reflection signal and a level of the signal, whereby the presence or absence of an article other than metal and the kind of the article can be detected regardless of whether a container holding the article is transparent or opaque.
