Telemetering remote-reading surface type nucleon moisture density meter

Abstract

The telemetering remote-reading surface type nucleon moisture densitometer includes gamma-source positioning rod on which a handle is mounted and source rod which are fixed on the machine shell. The gamma-ray source is placed in the base end portion of source rod, the neutron ray source is fixed in bottom portion of machine shell, the gamme-ray detector and neutron ray detector are placed in the bottom portion of machine shell, and the panel on which the display screen and operation keyboard are mounted is placed on the panel of the machine shell, and the telemetering on-palm controller whose interior is equipped with wired control circuit of wireless control circuit is connected with keyboard of moisture densitometer by means of interface, and the computer and printer are connected with moisture densitometer keyboard by means of interface.

Description

Technical field: [0001] The remote measurement and remote reading surface type nucleon moisture density meter of the invention belongs to the engineering construction quality detector. Background technique: [0002] The surface-type nuclear moisture density meter is a test instrument used for moisture and density measurement in road, railway, water conservancy projects and other projects. The instrument uses gamma rays, neutron rays and corresponding detectors to measure the density and moisture of the medium, that is, it uses the principle of absorption in the process of transmission and scattering when gamma rays interact with substances to measure density; The water content is measured by the principle that the interaction between fast neutrons and hydrogen atoms is moderated. The instrument has the function of fast and non-destructive measurement. The inspectors can directly read the wet density, dry density, water content, water content, compaction and other soil mecha...

Problems solved by technology

Sometimes the ambient background light is too strong, such as under the sun, or the light is too weak, such as at night, the LCD screen is often difficult to see, so data recording errors often occur

For the construction inspection of the test section of a large-scale project, many design, research, and construction personnel often need to know the test results of the test data and discuss and study the construction plan at the construction site of the project. Sometimes there are many people watching the instrument. , reading data and construction are inconvenient, and at the same time, people around the instrument will be exposed to unnecessary radiation
