An accelerometer measures physical acceleration experienced by an object. An accelerometer provides an accurate measurement of acceleration, stress levels, load factors, transmissibility coefficients and fatigue values. Accelerometers are used in many industries as well as in everyday objects such as smartphones, digital cameras, and video game controllers. For accelerometers in aircrafts, AMETEK produces Piezoelectrical, and Inertial.
How does an Accelerometer work?
An accelerometer uses electromagnetic sensing that measures the vibration of a structure, in our case, an aircraft. The force that is caused by the vibration causes the accelerometer to produce an electrical charge indicating how much force was exerted. Accelerometers simplify the acceleration by converting it to measurable signals.
What types of Accelerometers are offered by AMETEK?
Piezoelectrical:
Piezoelectricity is electricity resulting from pressure. These accelerometers are available in three operating modes:
AMETEK supplies bolted shear type accelerometers for applications up to 350°C and compression type accelerometers for applications up to 600°C. Given a maximum mounting temperature of 490°C and maximum surrounding air temperature of 378°C.
Inertial:
Inertial accelerometers are used in military and commercial aircrafts that are equipped with digital flight data recorders, or DFDR. These provide input to the aircraft “black box” and can be analyzed if the airplane crashes. It provides lateral, longitude and vertical acceleration data.
SFMS OVERVIEW
AMETEK Sensors and Fluid Management Systems (SFMS) is a global leader in the design, test and manufacturing of sensing products for the commercial, military-defense, business-jet and space markets. These sensors support applications related to temperature, pressure, fluid level, fluid flow, position, and acceleration/speed, many of which need to operate in harsh operating environments. SFMS has been producing product for systems operating on the most critical commercial and military aircraft programs in aerospace history.
