0~3 V Whole temperature range self-testable Triaxial Accelerometer
Sensor Module
1. Product Description
Instruments designed to measure acceleration, commonly found in
vehicles like automobiles, ships, aircraft, or spacecraft, as well
as in structures or machinery experiencing vibrations. These
accelerometers are equipped with analog voltage output and possess
features such as small size, light weight, a broad measuring range,
impact resistance, and reliable vibration performance.
An Accelerometer, also known as an Acceleration Sensor, is
specifically designed to quantify the force associated with
accelerated motion, often expressed as a relative ratio to the
acceleration of gravity (G). These accelerometers, leveraging
advanced iMEMS technology, exhibit high stability, compact
dimensions, lightweight construction, and instant startup
capabilities. They find applications in both vibration measurement
and static inclinational angle measurement.
Accelerometers, or acceleration sensors, play a crucial role in
measuring the force associated with the accelerated motion of
objects. Here are some additional details about accelerometers:
Principle of Operation: Accelerometers operate on the principle of
sensing changes in acceleration through the use of various
technologies. Common types include piezoelectric, piezoresistive,
capacitive, and micro-electromechanical systems (MEMS).
Acceleration Units: Acceleration is often measured in units of
gravitational force, denoted as "G," where 1 G is equal to the
acceleration due to Earth's gravity (approximately 9.8 m/s²).
Accelerometers provide readings as a multiple of G.
Applications:
Vibration Measurement: In industrial settings, accelerometers are
used to monitor and analyze vibrations in machinery, helping to
identify potential issues or improve performance.
Automotive: Accelerometers are integral to vehicle safety systems,
such as airbag deployment and stability control.
Aerospace: In aviation and space applications, accelerometers
assist in navigation, guidance, and control systems.
Consumer Electronics: Many devices, like smartphones and game
controllers, use accelerometers for features such as screen
orientation and motion sensing.
MEMS Technology: Modern accelerometers often leverage MEMS
technology, which allows for miniaturization and integration into
various devices. MEMS accelerometers are known for their small
size, low power consumption, and cost-effectiveness.
Vibration Measurement: Accelerometers are widely used in predictive
maintenance strategies, where changes in vibration patterns can
indicate potential equipment failures before they occur.
Inclinational Angle Measurement: In addition to measuring
acceleration, accelerometers can be utilized to determine the angle
of tilt or incline with respect to gravity. This is particularly
useful in applications requiring precise angular measurements.
Output Signals: Accelerometers commonly provide analog voltage
output or digital signals, making them compatible with a range of
data acquisition and processing systems.
Calibration: Proper calibration is essential for accurate
accelerometer readings. Calibration processes account for factors
like sensitivity, cross-axis sensitivity, and temperature effects.
Accelerometers have become integral components in various
industries and applications, contributing to advancements in
technology, safety, and predictive maintenance.
