PERISTALTIC PUMP WITH PRESENCE OF LIQUID SENSOR |
摘要 |
The present invention provides a highly universal out-of-liquid sensor that allows an out-of-liquid condition to be accurately detected for a long time, and provides a liquid supply device using the same. The out-of-liquid sensor (1), that is mounted in a liquid supply route for supplying a liquid to a predetermined location and forms a part of the liquid supply route, comprises a light-transmissive tubular body (2), the opening at one end of which is formed into a connecting section (4) capable of communicating with an upstream piping (16) of the liquid supply route, and the opening at the other end of which is formed into a connecting section (5) capable of communicating with a downstream piping (16') of the liquid supply route, and in which an internal bore section (6) communicating between the two connecting sections (4) and (5) is formed in the liquid-transmitting channel; and also comprises a photosensor (3) mounted on the tubular body (2), the detector (11) of the photosensor (3) being constructed to sense, through the light-transmissive wall surface of the tubular body (2), the presence or absence of a liquid flowing through the internal bore section (6). |
