Description
Technical field
The utility model belongs to sensor technical field, is specifically related to the much higher function soil sensor of a kind of precision.
Background technology
Soil is the important component part of natural ecological environment, with human lives and activity in production closely related.As porous medium, soil is by solid, liquid, gas three phase composition, and mineral matter and organic matter form its solid-phase construction, the hole in water and air filling structure.In Agricultural Activities, the holard is the important leverage of plant life, not only affects the effective utilization of crops to fertilizer, and relevant with the series reaction occurred in soil.Soil moisture content is the important parameter determining soil physics, chemistry and biological character and process.The flow of water of the holard determines the validity of its moisture.At present, the measuring method that characteristic curve of soil moisture is conventional is: utilize distinct device to measure soil matrix gesture and soil moisture content respectively to same soil sample, and it is not only loaded down with trivial details that it measures program, and time-consumingly takes a lot of work.Although domestic and international many scholars did specific aim research, location observation while also not having a kind of technology can realize soil matrix gesture and soil moisture content at present.
When the kind of the pressure transducer of pre-test water is a lot, main typical piezoresistive silicon sensor, has certain defect for the pressure survey of water in thickness mud and soil; Because piezoresistive silicon sensor is silicon microchip structure, cannot directly measure water in thickness mud and soil, and harder particle shape destructible 316L stainless steel diaphragm sensitive surface in them, may be had, to such an extent as to affect the measuring accuracy of sensor.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide the much higher function soil sensor of a kind of precision, sensor miniaturization, the feature that corrosion-resistant, measurement range is wide and stability is good, by the mode of Real-Time Monitoring, hydraulic pressure in soil being detected, causing loaded down with trivial details, the time-consuming problem of taking a lot of work of mensuration program to solve legacy equipment because measuring respectively.
The technical scheme that the utility model is taked is:
The much higher function soil sensor of a kind of precision, it is characterized in that, Silicon pressure core body " O " RunddichtringO is arranged on armouring inside pipe casing, the top of armouring sleeve pipe is provided with compression fittings by screw thread, pressure ring is connected compression Silicon pressure core body by screw thread with compression fittings, signal processing circuit board is fixed on pressure ring by mounting screw, and housing and compression fittings pass through argon arc welding integrally, this whole interior embedding silica gel; Porous cup is closely contacted on one end of described armouring sleeve pipe, the built-in hollow circular-tube of porous cup, and the deionized water in hollow circular-tube is outwards overflowed by porous cup; Induction contact is arranged on the other end of armouring sleeve pipe, the internal pressure change of induction hollow circular-tube.
Further, described armouring sleeve pipe is made up of stupalith.
The beneficial effects of the utility model are:
The utility model utilizes an equipment can measure soil moisture content and soil matrix gesture simultaneously, directly exports characteristic curve of soil moisture, and process of measurement is simple, and measurement result is objective and accurate.This sensor has that permeance property is good, volume is little, lightweight, all steel watertight structure, withstand voltage etch-proof feature; The advantages such as stability is good, and synthesis precision is high, and error is little.
