Features
very high overload resistance
insensitive to interference by magnetic and electric fields
lower cut-off frequency is zero, hence suitable for measuring static acceleration, such as gr***ity (inclinati***) or radial acceleration (centrifugal force)
linear frequency resp***e with little or no resonant peak at upper cut-off frequency
low non-linearity
high signal-to-noise ratio
no measurable hysteresis of signal
hermetically sealed
high long-term stability
***all temperature drift
integrated sensor electronics
analog DC or pulse width modulated or frequency modulated output
low power c***umption
very short on-transition delay
multiple housing opti***
Description
The sensors B1, B2 and B3 are capacitive spring-mass accelerometers with integrated electronics. Resonant peaks are minimized by special gas-dynamic damping in the primary transformer.
The sensors are manufactured with an analog DC output. The sensor electronics require only ***all amounts of power and are in conjunction with the capacitive primary transformer characterized by low error and high long-term stability.
Application
The accelerometers B1, B2 and B3 are used for applicati*** requiring high overload tolerance, high long-term stability, ***all lower cut-off frequency down to measurement of static acceleration, very short on-transition delay and low power c***umption. Typical applicati*** include:
measurements on vehicles, machinery, buildings and plants for process control and error diagnosis
sei***ic measurements
inclination measurements
safety engineering
dynamic measurement of position and velocity
