THY-KB-gravity detector product information
The surface of the Earth any objects are subject to the Earth's
gravity, the surface of the Earth's gravity changes the location.
Changes in gravity and density of underground uneven distribution
of the material, and material density and distribution of mineral
and geological structure and distribution are closely linked, study
and understanding of gravity anomaly can infer the structure of the
earth, the tectonic, the exploration of mineral resources.
The application of the law of gravity to a large extent depend on
the gravity measurement equipment used by. In the oil and mineral
exploration and structural studies in areas such as the use of the
gravity detector is the relative gravity detector, this product is
the relative Gravimeter quartz spring.
The equipment for its reliability and ease of operation and has
been recognized throughout the world. Because of the low human
consumption, high output data characteristics, its operating costs
low. In many inaccessible areas, from an economic point of view,
the gravity measurement instrument that has become more practical.
Seismic quartz components:
Gravimeter flexible system from a quartz. It is a three-spring
device, and the length of the main spring for the pre-tension
structure, to provide the necessary measurement sensitivity. It's a
very low moment of inertia. Light quartz improve the quality and
flexibility so that the quality of a gravity-a relative seismic
equipment. In the process the need to prevent the movement of the
damage caused by clamping apparatus. Quartz components are sealed
in a vacuum part of the device in order to protect their free from
pollution and to eliminate as a result of changes in atmospheric
pressure caused the error.
Superb technical, technological and quality assurance:
Under the conditions of processing in the laboratory scale, to
ensure that all instruments are consistent in the whole range of
scale. Small grid value in the whole range of linear and are in the
field measurements grid value will not change.
All components for the manufacture of gravity in the technology and
strict quality control. Through long-term and unremitting the
design and performance specifications of the improved and the
continuous development of technology and technical personnel in the
manufacturing, testing and maintenance of the experience
accumulated instrument to ensure that its gravity-all in the
leading position. Instrument testing and manufacturing equipment
and the special conditions in any place are the most sophisticated
and extensive.
