Description

The Seika BA Series accelerometer of high overload resistance with integrated electronics and normalised voltage output for measuring static and dynamic acceleration in the frequency range 0 to several 100Hz. BA1, BA2 and BA3 are capacitive spring-mass based accelerometers with integrated electronics. The resonant peaks are minimised by gas-dynamic dampening in the primary transformer.

MAIN FEATURES for Seika BA Series Accelerometer

• Very high overload resistance
• Insensitive to interference by magnetic and electric fields
• Lower limiting frequency is zero; hence suitable for measuring static acceleration such as gravity (inclination) or radial acceleration (centrifugal force)
• Integrated sensor electronics including normalising amplifier and low pass filter
• Hermetically sealed
• High long-term stability
• Linear frequency response without (BA1) or with only small (BA2, BA3) resonance peak at the high end of the frequency range
• Excellent signal to noise ratio
• Small temperature drift
• Low distortion
• No measurable hysteresis
• Small transverse sensitivity
• 9 to 30V operating voltage, short turn on delay, low current consumption
• Normalised 0 to 5V voltage output

BA Series accelerometers are used for applications requiring high overload tolerance, high long-term stability, low limiting frequency of 0Hz enabling static acceleration measurements, very short turn on delay, low power consumption and normalised output signal. Typical applications include:

• Measurements on vehicles, machinery, buildings and constructions for process control and surveillance
• Seismic measurements
• Inclination and acceleration measurements on moving objects likes vehicles, ships and aircraft
• Seismic measurements
• Dynamic determination of location and velocity

SEIKA develops, manufactures and distributes sensors for measurement of physical quantities and electronic and mechanical accessories for sensors. Inclinometers for nearly all existing tilt measurements and a series of robust accelerometers with integrated sensor electronics are SEIKA’s standard products. Next to these, SEIKA also manufactures a number of customer specific sensors.

Next to these standard products, Seika also manufactures level and humidity sensors for special applications as well as electronic components and sensor accessories.
