Displacement measurement is the measurement of changes in directed distance (displacement). Devices measuring displacement are based on displacement sensors, which can be contacting or non-contacting. [1] Some displacement sensors are based on displacement transducers, [2] devices which convert displacement into another form of energy. [3]
A displacement receiver, also known as a displacement sensor, displacement transducer, or displacement gauge, is a device that responds to or is sensitive to directed distance (displacement). [ citation needed ]
A gyroscope (from Ancient Greek γῦρος gŷros, "round" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientation and angular velocity. [1] [2] It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself.

A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
is the displacement vector – the distance from its equilibrium length. F {\displaystyle F} is the resulting force vector – the magnitude and direction of the restoring force the spring exerts k {\displaystyle k} is the rate , spring constant or force constant of the spring, a constant that depends on the spring's material and construction.
Many indicators have a mounting lug with a hole for a bolt as part of the back plate. Alternatively, the device can be held by the cylindrical stem that guides the plunger using a collet or special clamp, which is the method generally used by tools designed to integrate an indicator as a primary component, such as thickness gauges and comparators.
A seismometer is an instrument that responds to ground displacement and shaking such as caused by quakes, volcanic eruptions, and explosions.They are usually combined with a timing device and a recording device to form a seismograph. [1]
