GSM-19T proton precession magnetometer

The proton of a hydrogen nucleus is a positively charged particle that continuously spins and possesses a certain degree of magnetism. Under the influence of an external magnetic field, spin protons will align in a certain direction, known as nuclear paramagnetism. But its magnetism is very weak, only reflected in some diamagnetic substances with very low magnetic susceptibility, such as certain carbon hydroxide compound liquids(Water, alcohol, glycerin, etc)In these samples, protons are excited by a strong magnetic field and exhibit—By arranging in a fixed direction and removing the external magnetic field, protons under the influence of the geomagnetic field will be arranged in the same direction—Phase around geomagnetic fieldTRotation frequencyfThe unit is gamma. When the frequency is measuredfIn the future, the total magnetic field strength can be calculatedTThe numerical value. The instrument made using this principle is called a proton precession magnetometer, also known as a nuclear precession magnetometer(proton—precession magnetometer ).

The proton precession magnetometer has good stability. Low temperature impact, no zero point grid drop, high accuracy, no need for accurate orientation when observing weak magnetic anomalies, suitable for observation in motion.

GSM－19TMain advantages of standard magnetometer:

l It integrates high precisionGPS(Optional)

l Real time display of observed magnetic field images on the host screen

l pass throughRS232Interface, fast download of observation data, download speed up to115kbaud

l High resolution up to0.01nT,Sensitivity up to0.05nT

l The standard memory is32MB

l It has a unique programmable base station observation function. For example, the field magnetometer is connected to the base station to automatically calibrate daily variations; Flexible setting of observation schedule and sampling rate series; When you leave the base station for a long time, this function becomes particularly important

l useGSM－19TofWalking　MagThe acquisition mode ensures that the operator can collect magnetic field data while walking in the field, thereby obtaining continuous observation profiles

l GSM－19TAnother innovation is that users can input their designed observation routes and points into the officeGPS(Optional), and thenGPSCommand operators to observe in the field according to the design

l High precision time synchronization between base station observations and field flow observations is crucial for ensuring high-precision observation results in areas with magnetic interference

l Equipped with observation quality monitoring function, if a low quality observation value is detected during the measurement process, the operator will hear a warning signal.
