53 | 53A Auto Safety Testing Accelerometer
Small, compact triaxial Accelerometer designed for vehicle impact and road testing
About the 53 | 53A Auto Safety Testing Accelerometer
The Model 53 Accelerometer is a small, compact triaxial device designed for vehicle impact and road testing. The accelerometer incorporates gas-damped MEMS sensing elements with mechanical stops for high overload protection. Featuring ranges from ±50g to ±2000g and frequency response to 5000Hz, this sensor is easily mounted in hard to reach places on vehicles under test.
