Key Differences
Gravimeters are specialized instruments used primarily by geophysicists to measure variations in Earth's gravity, which helps in identifying underground structures. On the other hand, gravitometers can refer to any device that measures gravitational forces, which includes not only gravimeters but also other types of instruments used in various fields such as physics and astronomy.
Gravimeters are highly sensitive and provide precise measurements, which are crucial for tasks such as oil and mineral prospecting, and understanding geological formations. Whereas gravitometers can vary in their sensitivity and applications, depending on their design and the specific nature of the gravitational measurements they are intended to capture.
In practical use, gravimeters are often portable and used in field studies to assist in the mapping of geological variations. Conversely, gravitometers might be found in more diverse settings, from laboratory environments for fundamental physics experiments to industrial applications where gravitational measurements are needed.
Technically, all gravimeters are gravitometers, but not all gravitometers are gravimeters. This distinction highlights that while gravimeters have a specific application related to geophysical surveys, gravitometers encompass a broader category of instruments.
Both devices are crucial in their respective domains, with gravimeters playing a key role in earth sciences and gravitometers extending their use into broader scientific and industrial applications.
