The new model BST 24C is a triaxial accelerometer based on piezo resistive technology. With a four-active arm Wheatstone-Bridge (4 wire system) configuration and a damping ratio 0.7 helps to connect the sensor on all data acquisition systems. The light weight and small size of the sensor makes it easy to mount it on difficult places. The sensor is useable for crash test and flatter test. Do to the anodized aluminium housing the mounting is easy with a glue. The sensor has 6 m very high rugged and flexible 4-wire per axe cable. As an option, we supply the sensor with a Dallas ID and a Shunt resistor in the connector if it possible.
