Automotive Decelerometers – Are?
BrakeCheck is a decelerometer but what is a decelerometer ?
Decelerometers, also known as deceleration sensors or deceleration meters, are devices used to measure and quantify deceleration or negative acceleration. Deceleration refers to a decrease in velocity over time, and it is commonly associated with the braking or slowing down of an object or vehicle. Decelerometers are widely used in various applications, particularly in the automotive industry for safety and performance monitoring. They are often integrated into vehicles, specifically in systems such as airbags and electronic stability control (ESC) systems. These sensors play a crucial role in detecting sudden deceleration events, such as collisions or rapid braking, and triggering appropriate safety measures. The working principle of decelerometers typically involves the use of microelectromechanical systems (MEMS) technology. MEMS decelerometers consist of a tiny mass suspended on a spring-like structure. When subjected to deceleration forces, the mass moves relative to the sensor housing, causing a change in electrical output. This change is then measured and converted into acceleration or deceleration values. The output of a decelerometer is usually expressed in units of acceleration, such as meters per second squared (m/s²) or gravitational force (g). Some advanced decelerometers may also provide additional information, such as the direction of deceleration or rotational acceleration. Besides automotive applications, decelerometers can be found in other fields where the measurement of deceleration is important. For example, they are used in aerospace engineering to monitor the deceleration forces experienced during spacecraft re-entry or landing. They are also utilized in sports science to assess the impact forces on athletes during various activities, such as running or jumping. Overall, decelerometers are valuable tools for measuring and analysing deceleration forces in different contexts, contributing to safety, performance evaluation, and research in various industries. aide automotive market the BrakeCheck Decelerometer for automotive use in the UK MOT garages and HGV Brake testing.
