本考案は、水分計に関し、更に詳しくは、幅の
広い被測定物の水分含有度合の分布等を測定する
ことができる水分計に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a moisture meter, and more particularly, to a moisture meter that can measure the distribution of moisture content of a wide range of objects.
従来の水分計の一例を第２図に示す。 An example of a conventional moisture meter is shown in Figure 2.
この水分計１１は、接地電極１２と非接地電極
１３の間に被測定物Ｓを介在させて、その電極間

間容量を測定し、その電極間容量に基づいて被測
定物Ｓの水分含有度合を計測するものである。 This moisture meter 11 measures the inter-electrode capacitance by interposing the object S to be measured between the grounded electrode 12 and the ungrounded electrode 13 to form an AC bridge circuit 14 including the inter-electrode capacitance. The degree of moisture content of the object to be measured S is measured based on the capacitance.
このような水分計は、例えば抄紙工程や布の乾
燥工程等におけるプロセス制御用データを得るの
に用いられている。 Such moisture meters are used, for example, to obtain data for process control in paper making processes, cloth drying processes, and the like.
近年、プロセス制御技術が発達すると、従来の
ような全体的な水分含有度合のデータを得るだけ
にとどまらず、被測定物の部位毎の水分含有度合
を得たいとする要求が高まつてきた。
In recent years, with the development of process control technology, there has been an increasing demand for not only obtaining data on the overall water content as in the past, but also obtaining data on the water content of each part of the object to be measured.
そこで、接地電極１２と非接地電極１３の対を
被測定物の部位毎に多数設けることが提案された
が、構成が極めて複雑になる問題点があつた。 Therefore, it has been proposed to provide a large number of pairs of grounded electrodes 12 and non-grounded electrodes 13 for each part of the object to be measured, but this poses a problem in that the structure becomes extremely complicated.
また、電極対を被測定物に沿つて移動させるこ
とも提案されたが、接地電極と非接地電極とは被
測定物の両側にあるので、これらを同時に対向条
件を変えないで移動させるのは技術的な困難性が
あつた。 It has also been proposed to move the electrode pair along the object to be measured, but since the grounded and non-grounded electrodes are on both sides of the object to be measured, it is difficult to move them simultaneously without changing the opposing conditions. There were technical difficulties.
従つて、本考案の目的とするところは、実施容
易な構成によつて、被測定物の部位毎の水分含有
度合を測定できるようにした水分計を提供するこ
とにある。 Therefore, it is an object of the present invention to provide a moisture meter that can measure the moisture content of each part of an object with an easy-to-implement configuration.

The moisture meter of the present invention is a moisture meter that interposes an object to be measured between a grounded electrode and a non-grounded electrode to measure the capacitance between the electrodes and obtain the degree of moisture content. The structure is characterized in that it has a longer length than the non-grounded electrode, and the non-grounded electrode is configured to be movable in at least the one direction.
本考案の水分計では、接地電極は比較的サイズ

小さいのでこれも技術上の問題はない。さらに、
移動させるのは非接地電極だけであるから、高度

In the moisture meter of the present invention, although the ground electrode is relatively large in size, it is fixed and there is no technical problem. On the other hand, the non-grounded electrode is moved, but this is also not a technical problem since it is relatively small in size. moreover,
Since only the non-grounded electrode is moved, it can be easily carried out without requiring advanced techniques.
これら電極を用いて得られる水分含有度合は、
比較的サイズの小さい非接地電極の近傍の水分含
有度合である。従つて、非接地電極を所望の部位
に移動して測定すれば、被測定物の部位毎の水分
含有度合が得られる。 The moisture content obtained using these electrodes is
This is the moisture content near a relatively small non-grounded electrode. Therefore, by moving the non-grounded electrode to a desired location and performing measurement, the degree of moisture content for each location of the object to be measured can be obtained.
また、接地電極は固定であるから、重量を気に
することなく堅固に製作でき、測定の安定性も向
上する。 In addition, since the ground electrode is fixed, the device can be manufactured robustly without worrying about its weight, and the stability of the measurement is improved.
以下、図に示す実施例に基づいて本考案を更に
詳しく説明する。なお、これにより本考案が限定

Hereinafter, the present invention will be explained in more detail based on the embodiments shown in the drawings. Note that the present invention is not limited thereby.
第１図は本考案の一実施例の水分計１を概念的
に示したものである。 FIG. 1 conceptually shows a moisture meter 1 according to an embodiment of the present invention.
接地電極２は、固定されていて、比較的大きな
サイズ（例えば１ｍ×15cm）である。 The ground electrode 2 is fixed and has a relatively large size (for example, 1 m x 15 cm).
これに対し、非接地電極３は、比較的小さなサ
イズ（例えば15cm×10cm）であり、ホルダ５で支
持され、そのホルダ５はロツド６に沿つて移動可
能になつている。ホルダ５の移動はドライブ回路
７によつて制御される。 On the other hand, the non-grounded electrode 3 has a relatively small size (for example, 15 cm x 10 cm) and is supported by a holder 5, which is movable along the rod 6. Movement of the holder 5 is controlled by a drive circuit 7.
接地電極２のサイズは、非接地電極３の移動方
向について非接地電極３より例えば５cm以上大き
くするか又は1.5倍以上の大きさにしなければ、
非接地電極３を移動式とするメリツトは小さい。 The size of the grounded electrode 2 must be, for example, 5 cm or more larger than the non-grounded electrode 3 in the moving direction of the non-grounded electrode 3, or 1.5 times or more larger.
The advantage of making the non-grounded electrode 3 movable is small.
被測定物Ｌは、例えば連続した布であつて、ロ
ツド６と直交する方向に走行して１る。 The object to be measured L is, for example, a continuous piece of cloth, and runs in a direction perpendicular to the rod 6.
このような水分計１で、所望の部位に非接地電
極３を移動し、交流ブリツジ回路４によつて電極
間容量を測定すると、非接地電極３の近傍の被測
定物Ｌの水分含有度合を得ることが出来る。 In such a moisture meter 1, when the non-grounded electrode 3 is moved to a desired location and the inter-electrode capacitance is measured by the AC bridge circuit 4, the moisture content of the object L near the non-grounded electrode 3 can be determined. You can get it.
被測定物Ｌの異なる部位における水分含有度合

５を移動し、そこで電極間容量を測定し、水分含
有度合を得ればよい。 If it is desired to obtain the degree of moisture content in different parts of the object L, the holder 5 may be moved by the drive circuit 7, the capacitance between the electrodes may be measured there, and the degree of moisture content may be obtained.
この時、移動させるのはサイズの小さい非接地
電極３だけなので、特に高度の技術を必要とせず
に移動させることが出来る。 At this time, only the small-sized non-grounded electrode 3 is moved, so it can be moved without requiring particularly sophisticated techniques.
接地電極２は、移動させる必要がないので、重
量を気にせずに堅固に作られており、安定であ
