Description
The SEIKA B Series accelerometer sensors B1, B2 and B3 are capacitive spring-mass accelerometers with integrated electronics. Resonant peaks are minimised by special gas-dynamic damping in the primary transformer. SEIKA sensors are manufactured with an analogue DC output. The sensor electronics require only small amounts of power and are in conjunction with the capacitive primary transformer characterised by low error and high long-term stability. The B Series accelerometer is of high overload resistance with integrated electronics for measurement of acceleration in the frequency range 0 to several 100 Hz.
MAIN 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 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
- Analogue DC or PWM or FM output
- Low power consumption
- Very short on-transition delay
- Multiple housing options
The B Series accelerometers 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 application include:
- Measurements on vehicles, machinery, buildings and plants for process control and error diagnosis
- Seismic measurements
- Inclination measurements
- Safety engineering
- Dynamic measurement of position and velocity
