A newer technology using microelectromechanical systems (MEMS) sensors enables tilt angle measuring tasks to be performed conveniently in both single and dual axis mode. Ultra-high precision 2-axis MEMS driven digital inclinometer/ tiltmeter instruments are available for speedy angle measurement applications and surface profiling requiring very ...
Two-axis inclinometers that are built with MEMS tilt sensors provides simultaneous two-dimensional angle readings of a surface plane tangent to earth datum. Typical advantages of using two-axis MEMS inclinometers over conventional single-axis "bubble" or mechanical leveling instruments may include:
Sometimes tilt sensors are incorrectly called inclinometers because the sensors simply generate a signal (as opposed to inclinometers that generate a reading and a signal). A basic circuit using a tilt sensor is shown here. For this assembly, the components used are: a tilt sensor, a 470 Ohms resistor, a LED and a 3V power supply.

Liquid capacitive inclinometers are inclinometers (or clinometers) whose sensing elements are made with a liquid-filled differential capacitor; they sense the local direction of acceleration due to gravity (or movement). [1] A capacitive inclinometer has a disc-like cavity that is partly filled with a dielectric liquid.

The slip indicator is actually an inclinometer that at rest displays the angle of the aircraft's transverse axis with respect to horizontal, and in motion displays this angle as modified by the acceleration of the aircraft. [1] The most commonly used units are degrees per second (deg/s) or minutes per turn (min/tr). [citation needed]
Examples of this form of articulation are found in the hip, where the round head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis; and in the shoulder joint, where the rounded upper extremity of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.
