Description

SL-2 CNC logging system ground integrated host

Abstract

SL-2 CNC logging system ground integrated host, it is use a single core cable connected with all kinds of exploring tube, the depth system of the winch and logging data upload computer. It is characterized by high strength, high impact resistance, sealing and waterproof, moisture-proof and dustproof, so as to meet the requirements of logging in horrible environmental conditions.

Features & Benefits

● Lightly and portable

● Positive and negative correction function the depth

● Match different pulse counts disks

● USB communication interface

● All connector interfaces adopt military-grade waterproof electrical connectors

FAQ

In gravity exploration (SI), what is the unit of gravity? How to convert gravity units between SI and CGS?

What are gravitational field and gravitational potential?

What is the normal gravity field of the earth? What are the rules for the change of the normal gravity field with latitude and altitude?

① The normal gravity field of the earth: Assuming that the earth is a rotating ellipsoid (reference plane), the surface is glossy, the internal density is uniform, or it is distributed in concentric layers, the density of each layer is uniform, and the deviation of the shape of the ellipsoid from the geoid is very small, then the gravity field generated by the earth is the normal gravity field.
② The normal gravity value is only related to the latitude, the smallest at the equator and the largest at the poles, with a difference of about 50,000 g.u.; the rate of change of the normal gravity value with latitude is the largest at 45° latitude, and zero at the equator and the poles; the normal gravity value decreases with increasing altitude, and its rate of change is -3.086 g.u.. The main feature of the long-term change is the "westward drift" of the geomagnetic elements, both the dipole field and the non-dipole field drift westward, and have a global nature.
