GPVT-W1-1 application field and working principle

GPVT-W1-1 (Gravity Potential and Voltage Transmitter) is a gravity potential and voltage measurement device. It is designed to measure the earth gravity potential and the potential difference between two points. It works in a wide range of temperature and pressure, and is widely used in Earth gravity potential and potential difference measurements. This article will discuss the applications and working principle of GPVT-W1-1.

Application Fields

GPVT-W1-1 is mainly used in research fields related to Earth gravity potential and potential difference measurements. It is an important instrument in many fields, such as geophysics, aerospace, and sea bottom survey. It can be used to measure the gravity potential on various surfaces and the potential difference between two points. In addition, GPVT-W1-1 is used to measure the gravity potential of boreholes and deep voids. Moreover, it is used in GIS (geographic information systems) to determine the height and location of an object.

Working Principle

GPVT-W1-1 uses three different working principles for its measurements. The first is the "gravity anomaly method", where the instrument is placed on a surface and the gravitational potential is measured by calculating the difference between the measured field and the expected field. The second working principle is the "bending magnitude method", where the instrument is placed between two points and the voltage is measured to determine the potential difference. The last working principle is the "ellipsoidal approach", where a reference ellipsoid is used to calculate the differences in earth\'s gravitational potential over various surfaces.

GPVT-W1-1 is composed of two parts- the main unit and the external unit. The main unit is composed of a sensor, a control board, and a transmitter. The electronic part of the system consists of a voltage-controlled oscillator, a power amplifier, and a digital-interface board. The external unit is designed to measure the ambient temperature and electromagnetic radiation. The voltage-controlled oscillator and power amplifier produce oscillating signals and amplifying them, respectively. The amplified signals are then processed by the digital-interface board. Finally, the processed signals are mechanically converted to provide potential and voltage values.

Conclusion

GPVT-W1-1 is a gravity potential and voltage measurement device with wide-ranging applications. It works using three different working principles- the gravity anomaly method, the bending magnitude method, and the ellipsoidal approach. The device is composed of two parts- the main unit and the external unit. This article has discussed the applications and working principles of GPVT-W1-1.
