Abstract

An apparatus for the measurement of moisture comprises a compound sensor pointer element formed by axially bonding together a pair of different, flexible materials, at least one of which responds to moisture by contracting or extending, whilst the other remains constant or responds in reciprocal fashion. The tip of the pointer moves over a graduated scale; its opposite end is inserted in test soil. An independent claim is included for a compound moisture sensor element.

Description

Die vorliegende Erfindung bezieht sich auf eine mechanische Messeinheit zur kontinuierlichen Erdfeuchtigkeitsüberwachung von Topf-, Balkon- oder Gartenpflanzen.The The present invention relates to a mechanical measuring unit for continuous soil moisture monitoring of pot, balcony or Garden plants.

Anwendungsgebieteapplication areas

Mechanische Überwachung der Erdfeuchtigkeit von Topf- oder Balkonpflanzen, Foyerbegrünungen oder Grabbegrünungen.Mechanical monitoring the soil moisture of potted or balcony plants, Foyerbegrünungen or Grave plantings.

Stand der TechnikState of technology

Bekannt ist nur bei der so genannten Hydrokultur die Bewässerungsüberwachung von Pflanzen mit einem durchsichtigen Röhrchen, das den Wasserfüllstand durch einen Schwimmer anzeigt. Hierbei handelt es sich jedoch nicht um eine Anzeige der Erdfeuchtigkeit.Known is only in the so-called hydroponic the irrigation monitoring of plants with a transparent tube, that the water level indicated by a float. This is not the case an indication of the earth's moisture.

Aufgaben der ErfindungTasks of invention

Die mechanische Bewässerungsüberwachung zeigt bauartbedingt die Erdfeuchtigkeit mittels eines Zeigers und einer dahinter angebrachten Skala an. Die Verschiebung des Zeigers an der Skala entsteht dadurch, dass das eine Material, des aus zwei unterschiedlichen Materialien bestehenden Feuchtigkeitsfühlers, sich stärker ausdehnt oder zusammenzieht, als das andere Material.The mechanical irrigation monitoring shows the nature of the soil moisture by means of a pointer and a scale attached behind it. The displacement of the pointer The result of this is that the one material consists of two different ones Materials existing moisture sensor, expanding more or contract, than the other material.

Ähnliches ist bei Temperaturregelung durch das sogenannte Bimetall bekannt.something similar is known in temperature control by the so-called bimetal.
