Source, sensor probe, protective resistance and data collecting instrument.Sensor probe need to be put to specific bit at the scene during measurement moisture content
Put, measure the position resistivity, measurement data is gathered by data collecting instrument, different resistivity can cause different measurement electricity
Pressure, correspondence moisture content is measured finally by voltage-plot of water cut.
The Chinese patent of Publication No. 103837501B discloses a kind of analysis method of moisture percentage in sewage sludge.The method includes
Light signal transmitter, fluorescence detector.Send the light of specific wavelength during measurement moisture percentage in sewage sludge to tested sludge using light source
Source signal, while collecting detection sludge into the reflection angle position of regulation in detection signal and light signal using fluorescence detector
The light signal of reflection, is contrasted by receiving lightwave signal, determines the moisture content of sludge.
The Chinese patent of Publication No. 103592248A discloses a kind of colorimetric estimation method of soil moisture content.The method
Organic solution including 0.1~30g/L CoCL2 6H2Os, absorbance-soil moisture content standard curve.Measurement soil moisture content
When the organic solution of 0.1~30g/L CoCL2 6H2Os is extracted into pedotheque to be measured, remove solid matter, obtain solution to be measured
Absorbance, surveyed absorbance is brought into the absorbance-soil moisture content calibration curve equation set up, and tries to achieve corresponding soil
Moisture content.
In sum, to solve disadvantages described above, it is made that following improvement.
