B1, B2 or B3 

The sensors B1, B2 and B3 are capacitive spring-mass accelerometers with integrated electronics. Resonant peaks are minimized by a special gas-dynamic damping in the primary transformer. The sensors are manufactured with an analog DC output. The sensor electronics require only small amounts of power and are in conjunction with the capacitive primary transformer and characterised by low errors and high long-term stability.


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 stabilitySmall temperature drift
• Integrated sensor electronics
• Analog DC or pulse width modulated or frequency modulated output
• Low power consumption
• Very short on-transition delay
• Multiple housing options
   
   
 
 
 
BDK3, BDK10, BDK100 

BDK3, BDK10 or BDK100 

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 characterised by low error and high long-term stability.

Features
