Abstract
A leaf thickness sensing device (1) having mounting apparatus (9, 10) for flexibly mounting the device adjacent a leaf whose thickness is to be sensed, a leaf support element (4) coupled to the mounting apparatus, a displaceable leaf abutting (6) juxtaposed with respect to and biased towards the leaf support element so as to be in firm, non-destructive abutting contact with a leaf to be releasably retained on the leaf support element; a displacement transducer element (11) responsibly coupled to the leaf abutting element and serving to generate a signal corresponding to displacement of the second element relative to the first element.
Claims5
A leaf thickness sensing device comprising mounting means for flexibly mounting said device adjacent a leaf whose thickness is to be sensed, a leaf support element coupled to said mounting means, a displaceable leaf abutting element juxtaposed with respect to and biased towards said leaf support element so as to be in firm, non-destructive abutting contact with a leaf to be releasably retained on said leaf support element;
- a displacement transducer element responsibly coupled to said leaf abutting element and serving to generate a signal corresponding to displacement of said second element relative to said first element.
An irrigation system comprising a leaf thickness sensing device according to any one of the preceding claims, an irrigation controller responsively connected to an output of said transducer and a main irrigation valve coupled to said controller and adapted to be actuated in response to sensed variations in said leaf thickness.
