Title: Photoelectric displacement gage
Inventor: TANI YOSHIHEI
IPC: G01F23/30
Filed: 1981-06-05
Abstract: PURPOSE:To obtain the compact and light weight displacement gate, by providing an optical means wherein a light reflecting body, light emitting and receiving elements, and the like are used, and detecting the displacement. CONSTITUTION:A light emitting diode 1 and phototransistors 2 and 3 are arranged on the same straight line so as to face the light reflecting body 4. The change of a float 8 is transmitted to a cam 10 by a linking rod 9. The cam 10 is rotated by DELTAtheta by the displacements DELTAh of a liquid surface, and the light reflecting body 4 is moved by DELTAl. When said reflecting body 4 is moved by DELTAl, the rate of change in the output of the phototransistor 2 reflecting body 4 is different from the rate of change in the output of the phototransistor 3 with respect to the displacement DELTAl of the light deflecting body 4. Therefore, by obtaining the output ratio, the distance to the light reflecting body 4 can be found. In this way, since almost negligible number of mechanical elements is used in the constitution of the detectors, the device can be made compart and light weight.
