Description
The B1, B2, and B3 sensors are capacitive spring mass accelerometers with integrated sensor electronics. Requiring very low power consumption these are characterized by a high degree of long-term stability. Resonant peaks are minimised by means of a special gas-dynamic damping in the primary transformer.
Manufactured with an Analog DC output, the integrated sensor electronics require only minimal power and are in conjunction with the capacitive primary transformer characterized by high accuracy, linearity, and long-term stability.
Applications
The B Series are used for applications requiring high overload tolerance, high long-term stability, small lower cut-off frequency down to measurement of static acceleration, very short on-transition delay and low power consumption.
Typical applications include:
measurements on vehicles, machinery, buildings, and plants for process control and error diagnosis
seismic measurements
inclination measurements (i.e. ±90º)
safety engineering
dynamic measurement of position & velocity
Features
Compact housing, less than 1” diameter
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 gravity (inclinations) or radial acceleration (centrifugal force)
Linear frequency response 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
Small temperature drift
Integrated sensor electronics
Analog DC or pulse width modulated or frequency modulated output
Low power consumption
Very short settling time Multiple housing options
