Document Type and Number:
Japanese Patent JP7376375
Kind Code:
B2
Abstract:
To provide a soil moisture measurement sensor that can set a flat detection area inside an earthwork structure by a grid-like integrated structure and a capacitance type moisture meter using this sensor.SOLUTION: A soil moisture measurement sensor 1 comprises: a grid section 10 consisting of a plurality of wires 11 arranged in parallel, wherein the plurality of wires 11 includes a plurality of first and second detection wires 11a and 11b, which are substantially parallel, connected by a plurality of spacing retaining materials 12; and a wire-like conductive portion 20 extending inside the first and second detection wires 11a and 11b. It also comprises a reinforcing section 30 that covers at least a part of the outer circumference of the conductive section 20. The capacitance type moisture meter comprises an analysis device that electrically connects the soil moisture measurement sensor 1 with the conductive portion 20 of the first detection wire rod 11a and the conductive portion 20 of the second detection wire rod 11b, and has a measuring unit that detects the capacitance in the detection area located between the first detection wire 11a and the second detection wire 11b and measures the amount of water in the detection area based on the capacitance.SELECTED DRAWING: Figure 1
