An accelerometer is a device that measures acceleration or gravity. Accelerometers are used in oil and gas exploration, in spacecraft and satellites, in rockets, aircraft, drones, ships, automobiles and other vehicles to detect acceleration, deceleration, or orientation with respect to the gravity of the earth. Accelerometers can also be used to measure vibration and shock. Quartz hinge Accelerometers employ a closed loop force balance system by which the proof mass is kept in place which makes them very accurate and repeatable. Open loop designs, such as those employed in MEMS accelerometers, lack this force balance and are more prone to failure but offer a performance to cost ratio suitable for a wide array of applications.

Examples include:

• Model 80 Accelerometer Sensor
• Model 60 Accelerometer Sensor
• Model 760 Directional Sensor (utilizes quartz hinge accelerometers)
• Model 544 Logging Sensor (utilizes MEMS accelerometers)

A magnetometer is a device that measures the direction, strength, or relative change of magnetic or electrical fields. There are many types of magnetometers and their use is spread across a wide spectrum of industries. Some of the applications in which magnetometers are utilized are for oil and gas exploration, in spacecraft and satellites, in rockets, aircraft, drones, ships, automobiles and other vehicles. Magnetometers are also used in laboratory, medical and other research applications to measure the magnetic fields of things as varied as a human brain, electrical currents or the magnetic properties of ancient rocks.

Examples include:

• Model 428D Magnetometer/Milliammeter
• Model 1540 Digital 24 Bit 3-Axis Fluxgate Magnetometer Sensor
• Model 536 High Accuracy 3-Axis Fluxgate Magnetometer

An azimuth is an angular measurement of the angle of an object in a spherical coordinate system. The vector from an observer to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane, such as true north, is called the azimuth.

An inclination is an angular measurement above or below the gravity horizon. Inclination is measured by an inclinometer, traditionally a spirit level that uses a bubble, but more accurately by using an accelerometer to measure gravity.

Gamma, or gamma ray or radiation is a form of electronic radiation arising from the radioactive decay of atomic nuclei. Gamma rays are the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (30×1018 Hz), it imparts the highest photon energy. Gamma rays are measured by a Geiger counter which detects ionizing radiation. Different materials emit different levels of gamma radiation and thus measuring gamma radiation indicates the nature of the material.
