Description
The dynamic accelerometers BDK3, BDK10, and BDK100 are capacitive spring-mass accelerometers with integrated sensor electronics. Resonant peaks are minimized by dynamic gas damping in the primary transformer.
The sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by low error and high long-term stability.
Application
The accelerometers BDK3, BDK10, and BDK100 are used for applications requiring high overload resistance, high long-term stability, small lower cut-off frequency, light weight and low power consumption. Typical applications include:
measurements on vehicles, machinery, buildings and plants for process control and error diagnosis
seismic measurements
vibration measurements
safety engineering
dynamic measurement of position and velocity
