Regarding detection.
この種の液体検知のために用いられるテープ状

As a tape-shaped liquid sensor used for this type of liquid detection, a ``conductive liquid detection sensor'' described in Japanese Utility Model Application Publication No. 58-96248 has been proposed.
This sensor has at least two sensing conductors spaced apart and sandwiched between two pieces of insulating tape, and a large number of through holes are provided in at least one of the insulating tapes at positions corresponding to the sensing conductors. By bridging the sensing conductors, the presence or arrival of liquid is electrically detected.

However, in order to obtain quick detection, these conventional tape-shaped liquid sensors are used by being attached to bare floor surfaces or equipment surfaces that require liquid detection, so other parts may come into contact with the sensor. The sensor is more likely to be damaged, and since it is exposed to the surface of equipment, the sensor deteriorates more quickly due to ultraviolet rays and oxidation, which shortens the sensor's lifespan.
そこでこの考案は、上記の欠点に鑑み、破損を
防ぎ、経年劣化を少なくした寿命の長い液体検知
装置を提供することを目的とするものである。 In view of the above-mentioned drawbacks, the object of this invention is to provide a liquid detection device that prevents breakage, reduces deterioration over time, and has a long life.

In order to solve the above problems, according to this invention, at least a pair of sensing conductors substantially juxtaposed,
A tape-shaped liquid sensor sandwiched between tapes having through-holes that can be bridged by incoming liquid is brought into surface contact so as to cover one side of the tape-shaped liquid sensor, and the tape-shaped liquid sensor is movable. The gist of the liquid sensing device is a liquid sensing device comprising at least one support piece that supports the liquid sensing device, and a holding band having locking means formed at both ends.

都合である。 In addition, in this configuration, if the tape of the tape-shaped liquid sensor is formed using a material with a low coefficient of friction, the sensor can be easily displaced, and the concentration of breakage stress due to expansion and contraction in response to environmental changes is eliminated, further reducing breakage. Furthermore, if this tape is formed using a fluororesin, it will have excellent weather resistance and thus have a long service life, which is advantageous.

標準品として便利になる。 In addition, in the configuration according to this invention, if locking means are provided at both ends of the retaining band and connectors are provided at both ends of the tape-shaped liquid sensor, it will be convenient to attach the liquid detection device alone. In addition, it can be used as a standard product because it can be connected in series with other devices, and can be attached to various types of equipment.

According to this invention, one side of the tape-shaped liquid sensor is covered with a retaining band, so if this sensor is placed on the side of various devices and the protective band is placed on the side exposed to the external environment, this retaining band covers the sensor. The liquid detection device can be protected from mechanical shock, aging deterioration caused by ultraviolet rays, oxidation, etc., and a liquid detection device with a long life can be obtained. Furthermore, since the sensor is movably supported within the holding band, it is possible to allow the sensor to expand and contract due to environmental changes, thereby eliminating stress concentration that could lead to damage, and extending the life of the sensor. In particular, forming the sensor tape using a material with a low coefficient of friction such as fluororesin is suitable for eliminating this stress concentration. In addition, if locking means are provided at both ends of the retaining band and connectors are provided at both ends of the sensor, it will be convenient to attach the liquid detection device.
In addition, it is convenient as a standard product because it allows such devices to be connected in series.
