törmäysantureilla

Törmäysanturit, also known as crash sensors or impact sensors, are devices designed to detect physical impacts or collisions. They are commonly used in various safety systems to trigger protective measures. In automotive applications, törmäysanturit are integral to airbag systems. When a significant impact occurs, these sensors register the deceleration and send a signal to the vehicle's control module, which then deploys the airbags to protect occupants. The sensitivity and placement of these sensors are crucial for timely and effective airbag deployment.

Beyond vehicles, törmäysanturit find use in industrial machinery to prevent damage from unexpected collisions. For instance, in robotics, they can halt a robot's arm if it encounters an obstacle, averting damage to the robot, the object, or surrounding personnel. They are also employed in security systems, such as in safes or vaults, to detect forceful attempts at entry.

The technology behind törmäysanturit varies, but common types include mechanical switches that close upon impact, piezoelectric sensors that generate a voltage when stressed, and accelerometers that measure rapid changes in velocity. The data from these sensors is processed to distinguish between a genuine collision and minor vibrations or jolts, ensuring that protective systems are activated only when necessary. This prevents false alarms and ensures reliability in critical situations.
