Title: Detection apparatus, detection method and sensor
Inventor: KASAI EIJI
IPC: G01N27/02
Filed: 1995-06-19
Abstract: PURPOSE: To detect an object, to be detected, with high accuracy irrespective of whether it is transparent or opaque even when it is a substance, e.g., such as a liquid, a pulverulent body or the like other than a metal by a method wherein an oscillation part which emits a high-frequency signal and a sensor part which contains a resonance circuit are installed. CONSTITUTION: A high-frequency signal is supplied to a sensor part 1 by an oscillation part 2 via a transmission line 4. When an object to be detected does not exist, the impedance of the sensor part 1 is matched with the impedance of the transmission line 4. As a result, the reflection of the sent high-frequency signal is nearly zero, and an output from a reflected-wave sensor 3 becomes zero. As a result, it is possible to detect that the object does not exist. When the object exists, the sensor part 1 is subjected to a magnetic infuence due to the difference in a permeability between the air and the object, and an impedance is changed.  When the impedance of the sensor part 1 is deviated to be larger than a matching impedance, a reflected signal becomes large, and the reflected signal is detected by the reflected-wave sensor 3, thereby detecting the existence of the object can be detected.
